    September 2017 

    It’s September, and as the nights get cooler and the students return to school, we leave summer behind and gear up for a productive fall season.  As we all know, the heating season is the best time to test for radon.  The challenge, of course, is to promote radon awareness and increase testing.

    Each year, as the radon testing season comes around, we find ourselves brainstorming new and improved promotion ideas.  However, sometimes it’s best to return to the basics.  To remember what has worked in the past and apply it to the future.  To look at our client base, understand what motivated them to test or mitigate, and reach out to their peers.

    To this end, CARST is pleased to offer a new webinar: Build Your Own Radon Awareness Campaign.  Our inaugural webinar dealt with social media, and met with good success this past August.  With our next webinar, we aim to take the mystery out of radon promotion by walking through the process step by step with professionals sharing some of their successful ideas.

    By the end of the webinar, you should have identified who your target audience is, how to reach them, and where to find the necessary resources to help you on the way.  So why wait?  Sign up for the webinartoday, and start this testing season off on the right foot. 

    Psst… Been to the CARST website lately? We’re sporting a fresh new look!  We’ve taken your feedback to heart to create a site that’s easier to navigate and contains more resources than ever; both for CARST members and for all Canadians.  Our homeowners’ pages aim to take the mystery out of radon and steer citizens to our C-NRPP professionals to test and mitigate their homes.  With links to government publications, radon in the news, videos and more; we really are Canada’s Radon Authority.

    Are you getting the most out of your membership? Login to our members-only section to access a variety of tools and resources designed to help you run and expand your radon business.  While you’re there, take a moment to update your member profile, which now includes space to list your additional qualifications to increase networking opportunities.  As ever, CARST’s strength lies in our members, and our diversity adds to our strength.

    August 2017 Newsletter: Unmasking the Faces of Lung Cancer

    Lack of public awareness is an all-too familiar challenge to all of us in the radon industry.  We’ve come a long way in the last 10 years, but to a great extent the general public is still by and large unaware of radon and the associated health risks.  It can be hard to answer the question “What’s radon?” over and over and not feel as though we’re running a single-handed public awareness campaign on top of running our radon businesses.

    However, for all our frustrations, there is another group of people who are even more keenly aware of the dangers of radon than we are.  Many of us have met these people in the course of our work; lung cancer victims, lung cancer survivors, and their loved ones. 

    As radon professionals, we all know the dangers posed by radon.  We know the statistics by heart and quote them frequently.  For those affected by lung cancer, the dangers of radon are more than statistics; they’re real, and they’re personal.

    For your average Canadian, “lung cancer” probably brings to mind the dangers of smoking and second-hand smoke.  Too few Canadians are aware that radon follows smoking as the second-leading cause of lung cancer, and that radon and smoking combined pose an even higher risk.  There can be no stronger advocates for radon awareness than those who have battled radon-induced lung cancer and survived.  With that in mind, CARST is pleased to be launching a new public awareness campaign; Unmasking the Faces of Lung Cancer.

    The goal of this campaign is to give those affected by lung cancer a voice, and in turn, give a face (in fact, many faces) to the dangers that most of us know only as statistics.

    For this project to succeed, CARST needs your help.  Have you met a lung cancer survivor in the course of your work?  Do you know someone who’s had their home tested or mitigated after a lung cancer diagnosis?  The project is a simple one: each participant will be asked to answer a short questionnaire, and submit a photo of themselves as one of the many faces of lung cancer.  Those who are interested may also be interviewed on camera to create a video.

    Each person who shares their story will help to gradually unmask the true face of lung cancer.  From those who “never smoked a day in their lives”, to those for whom years of smoking combined with high radon exposure proved deadly.  Victims, survivors, family members; each story becomes part of the bigger picture.

    The success of this campaign depends on your involvement.  Here is a link, to a short list of interview questions we’ve put together.

    Unmasking the Faces of Lung Cancer v3.pdf

    We encourage you to reach out to any contacts you may have either directly or by forwarding them our contact information.   They can email us a picture and the answers to the questions or they can enter the answers online on our website here.

    Finally, just in case you’re in the mood for some summer shopping, CARST has negotiated a special deal with HILTI, see details below in the Membership Discount.

    ACSTR/CARST Bulletin

     2017 Août

    Un message du président

    Bulletin de Août 2017 : Démasquer les visages du cancer du poumon

    La sensibilisation du public présente des lacunes et constitue un défi bien familier pour nous, les professionnels de l’industrie du radon. Nous en avons parcouru du chemin au cours des dix dernières années, mais de manière générale, la population reste encore largement non informée sur le radon et les risques de santé qui y sont associés. Il s’avère difficile de répondre sans cesse à la question « Qu’est-ce que le radon? » sans avoir l’impression que nous menons en solitaire une campagne de sensibilisation du public en plus de mener nos propres projets relatifs au radon.

    Toutefois, malgré toutes nos frustrations, nous devons nous rappeler qu’un certain groupe de personnes est particulièrement au courant des dangers du radon. Nombre d’entre nous en avons rencontré en raison de notre travail : les victimes du cancer du poumon, les survivants et leurs proches.

    En tant que professionnels du radon, nous connaissons les dangers liés au radon. Nous connaissons les statistiques par cœur et nous les citons fréquemment. Pour les gens touchés par le cancer du poumon, les dangers liés au radon constituent plus que des statistiques : ils sont réels et ils les vivent.

    La plupart des Canadiennes et Canadiens diront que le cancer du poumon est principalement causé par le tabagisme et la fumée secondaire. Peu de nos concitoyens savent que le radon suit le tabagisme en deuxième position des causes du cancer du poumon, et qu’ensemble, le radon et le tabagisme constituent un risque encore plus élevé. Personne ne peut présenter les risques liés au radon mieux que ceux qui se sont battus contre un cancer du poumon causé par le radon et qui ont survécu. C’est pourquoi l’ACSTR est heureuse de lancer sa nouvelle campagne de sensibilisation Démasquer les visages du cancer du poumon.

    Cette campagne vise à donner une voix aux gens touchés par le cancer du poumon causé par le radon, et en retour, à mettre un visage (plusieurs visages, en fait) sur les dangers que la plupart ne connaissent qu’en statistiques.

    L’ACSTR demande votre aide pour la réussite de ce projet. Avez-vous rencontré un survivant du cancer du poumon dans le cadre de votre travail? Connaissez-vous une personne qui a fait tester sa maison ou qui a demandé une atténuation du radon après un diagnostic de cancer du poumon? Ce projet est simple : chaque participant(e) devra répondre à un court questionnaire et envoyer une photo le ou la représentant comme étant l’un des nombreux visages du cancer du poumon. Les participants qui le souhaitent peuvent également donner une entrevue filmée pour créer une vidéo.

    Chaque personne qui partagera son histoire aidera à démasquer progressivement les vrais visages du cancer du poumon. Pour les gens qui n’ont jamais fumé une cigarette de leur vie à ceux dont les années de tabagisme combinées à une exposition à un niveau élevé de radon se sont avérées fatales. Victimes, survivants, proches; chaque histoire s’inscrit dans une vue d’ensemble.

    Le succès de cette campagne dépend de votre participation.  Voici un lien, Démasquer les visages du cancer du poumon Projet de sensibilisation au radon.docm vers une courte liste de questions d’entrevue que nous avons préparée.  Nous vous encourageons à communiquer avec vos contacts directement ou en leur transférant nos coordonnées pour nous joindre.  Ils peuvent nous envoyer leur photo et les réponses au questionnaire par courriel, ou encore inscrire leurs réponses dans le questionnaire en ligne sur notre site Web ici.

    Pour terminer, si vous avez une envie de magasinage estival, l’ACSTR a négocié un prix spécial avec le manufacturier HILTI. Consultez les détails ci-dessous concernant un rabais pour les membres.

    Des nouvelles du PNCR-C :

    En avril, le PNCR-R a recueilli des données de nos professionnels par l’intermédiaire de notre évaluation sur l’atténuation du radon. Il s’avère que parmi nos répondants, 76% d’entre eux mènent les atténuations du radon avec une dépressurisation du sol sous la dalle, et 18% utilisent la dépressurisation à l'aide d'un puisard. De plus, grâce aux données amassées, nous pouvons constater que la dépressurisation du sol sous la dalle reste la méthode d’atténuation du radon la plus efficace.

    Nous continuons la cueillette de données pour notre évaluation sur l’atténuation. Si vous n’avez pas encore participé, vous pouvez remplir le sondage ici.

    Si vous voulez partager des données sur vos atténuations pour les recherches du PNCR-C, vous pouvez utiliser la feuille de calcul Excel pour entrer vos données et l’envoyer par courriel à

    Our vision is to be the authoritative voice on radon in Canada and help Canadians reduce radon risk in their home, workplace and public environment by promoting public awareness, and supporting the transfer of radon information for the benefit of members, consumers and public at large.

    This summer, CARST and C-NRPP are pleased to be announcing a new level of partnership: as of July, all certified C-NRPP professionals will become members of CARST.  Joining forces with CARST will allow C-NRPP professionals to:

    • Benefit from CARST’s nation-wide partnerships and professional support programs
    • Clear up confusion on what is CARST and what is C-NRPP
    • Obtain preferred membership rates
    • Acquire increased access to the annual CARST conference, continuing education courses, and a growing number of webinars.  

    Bringing over 200 radon professionals into the fold means that the CARST community will grow that much stronger, allowing for greater sharing of ideas, resources and research.  The increased membership numbers will help CARST continue to grow and develop new initiatives to support all radon professionals.

    A simplified renewal process for both C-NRPP professionals and CARST members will make it easier for all members to stay up-to-date on their membership status,and not risk having their membership lapse unintentionally.  The membership fee structure has been revised with new membership packages available to help companies of all sizes find the membership package that works for them.

    Un autre congrès terminé! Les participants de cette année pourront le confirmer, le congrès 2017 de l’ACSTR s’est avéré un succès retentissant! C’est avec l’idée de solutions pratiques bien ancrée dans nos esprits que nous avons commencé le congrès avec une expérience pratique qui consistait en une sortie d’une journée sur le terrain le samedi. Ce nouvel ajout au congrès s’est révélé très populaire. Tellement que les places avaient toutes été réservées bien avant l’événement (prenez-en note pour l’an prochain!). Malgré les époustouflants panoramas de Banff qui captivait le regard de tous les participants, les cours de formation continue du dimanche n’ont pas du tout été délaissés. Au contraire, les participants étaient présents et motivés, si bien que nous avons parfois même manqué de chaises!

    Le lundi, nous avons vu avec un grand plaisir le président de l’ACSTR, Alan Whitehead, remettre le tout premier prix Reconnaissance Arthur G. Scott au Dr Dana Schmidt pour son travail à Castelgar, en Colombie-Britannique. Après le décès de sa femme en 2009, morte d’un cancer des poumons provoqué par le radon, le Dr Schmidt et son fils ont créé la Donna Schmidt Cancer Prevention Society, avec comme mission de réduire les cas de cancers des poumons provoqués par une exposition au radon à la maison et au travail, et ce, partout dans la région. Le Dr Schmidt est un militant et activiste passionné dans la lutte contre le radon, et a convaincu avec succès son conseil municipal d’apporter des modifications au Code du bâtiment. Ces modifications sont ensuite devenues des mesures de prévention du radon dans le Code du bâtiment provincial de la Colombie-Britannique. C’est pour nous un honneur de reconnaître le travail du Dr Schmidt et de lui remettre le tout premier prix Reconnaissance Arthur G. Scott.

    Autre nouveauté cette année, les Olympiques du radon! Cette activité très divertissante nous a permis de suivre quatre équipes de concurrents qui ont tout donné dans des compétitions qui allaient des jeux-questionnaires sur le radon à la coupe de tuyaux, en passant par le nettoyage de fosses de succion, le tout animé en grand par les commentaires de Bill Rounds et Mike Holmes Jr.  Une compétition intense, mais amicale, dont nous sommes tous sortis gagnants au final, puisque les événements nous ont fait bondir de nos chaises tant nous voulions plonger dans l’action.

    Revenons aux choses sérieuses! L’Assemblée générale annuelle s’est tenue le mardi 25 avril.  Le procès-verbal de l’Assemblée est accessible dans la section des membres du site de l’ACSTR.  Les élections du Conseil d’administration ont permis la réélection d’Alan Whitehead et de Rob Mahoney, ainsi que l’élection de Bruce Decker et Mark Donohue.  Nous souhaitons la bienvenue à Bruce et Mark au sein du Conseil et nous remercions ceux et celles qui ont pris le temps de voter.

    Enfin, l’ACSTR a le plaisir de vous annoncer que Pam Warkentin occupe maintenant le poste de directrice exécutive. Puisque l’ACSTR continue de croître et d’évoluer, ce nouveau poste reflète mieux ses tâches et responsabilités. Pour lui offrir un soutien quant aux tâches administratives, Erin Curry a été nommée adjointe administrative. Erin est inspectrice en bâtiment, membre de l’ACSTR et habite près de Montréal, au Québec. En collaboration avec le Conseil d’administration et d’autres comités bien dévoués à la cause, l’équipe administrative déploie un maximum d’efforts pour soutenir l’ACSTR dans l’atteinte de ses buts, tout en améliorant les services et en augmentant les avantages de l’adhésion.

    Another conference is behind us, and as those of you who attended this year can attest, CARST 2017 was a resounding success! With the theme of Practical Solutions firmly in mind, this year’s conference began with hands-on experience during the day-long field trip on Saturday. This new addition to the conference was very popular, and sold out well in advance (heads-up for next year).   Despite the beautiful scenery of Banff vying for everyone’s attention, the continuing education courses on Sunday were well-attended and engaging; in some cases we even ran out of chairs!

    On Monday it was with great pleasure that CARST President Alan Whitehead presented the inaugural Arthur G. Scott Achievement Award to Dr. Dana Schmidt for his work in Castelgar, British Columbia. After losing his wife to radon-induced lung cancer in 2009, Dr. Schmidt and his son established the Donna Schmidt Cancer Prevention Society, with the mission to reduce lung cancer from home and workplace radon exposure throughout the region.  Dr. Schmidt is a passionate radon advocate and activist, and has successfully lobbied his local council to make changes to the building code.  These changes eventually resulted in radon prevention measures being introduced into the provincial building code in British Columbia.  It is an honour to congratulate Dr. Schmidt on his work, and present him with the first Arthur G. Scott Achievement Award.   

    Another new addition to this year’s conference was the Radon Olympics!  This highly entertaining event saw participants form 4 teams to compete in everything from radon trivia to cutting pipe and clearing suction pits, with commentators Bill Rounds and Mike Holmes Jr. broadcasting the action.  The competition was intense but friendly, and ultimately we all came away winners as the events got us out of our seats and into the action.

    On a more serious note, the Annual General Meeting was held on Tuesday, April 25.  The minutes from the meeting are available in the Members section of the CARST website.  The results of the Board of Directors Election are as follows: both Alan Whitehead and Rob Mahoney were re-elected, and Bruce Decker and Mark Donohue have been added as new members of the board.  A warm welcome to both Bruce and Mark, and a thank you to all those members who took the time to vote.

    Finally, CARST is pleased to announce that Pam Warkentin has now moved into the role of Executive Director.  As CARST continues to grow and evolve, this new position better reflects her tasks and responsibilities.   Joining her to offer administrative support as Executive Assistant is Erin Curry.  Erin is a home inspector and CARST member based near Montreal, Quebec.  Together with the Board of Directors and various devoted committees, the administrative team is working hard to help CARST achieve our goals, all the while improving our services and increasing membership value.

    CARST/ACSTR & Lung Association-Ontario Urges Wynne Government To Protect Residential

    Tenants/Homeowners Lungs

    Protect residential homeowners and tenants from the dangers of radon

    Toronto- Now that the Ontario government is making housing more affordable, let’s make sure it’s safe. There is an invisible, radioactive gas which, according to Public Health Ontario, is linked to almost 850 deaths in Ontario per year.  It’s not expensive to test, not expensive to fix, but action is needed.  Radon gas needs to be included in these discussions of housing in Ontario.

    We have put a lot of effort into educating homeowners to test their homes and reduce their radon exposures, however not all Canadians are homeowners, and including radon testing as a requirement for landlords is an essential step in ensuring health equity when it comes to reducing radon risk and ensuring radon control measures are included in the building code will further reduce the future cost of reducing levels in all homes.    

    "People work hard to provide for their families. They should be able to rent or enter the real estate market without making great sacrifices or taking on a huge amount of risk. At the same time, we recognize the need to protect the significant investment homeowners have made. This plan balances those needs to stabilize the market and prevent a sharp correction that would be harmful to everyone."
     — Kathleen Wynne, Premier of Ontario


    Research conducted by Public Health Ontario researchers stated that 847 lung cancer deaths a year are attributable to radon. (Lung cancer risk from radon in Ontario, Canada: how many lung cancers can we prevent? August 2013) The researchers concluded that, “interventions that install effective radon-preventive measures into buildings at build may be a good alternative population prevention strategy to testing and remediation,” and “testing and remediation may also prevent a portion of radon-related lung cancer deaths.”

    “After listening to Virginia’s story-[below]- and knowing about the dangers of radon, we are highlighting the need for the Wynne Government to include in any Residential Tenancies’ Act or housing review, action concerning two policy options already on the table today to help protect Ontarians from the dangers of radon,” said Alan Whitehead, President and CEO, Canadian Association of Radon Scientists and Technologists (CARST/ACSTR).

    Ensuring Health Equity with Radon Risk Reduction needs to include changes in:

    1.  Residential Tenancies Act - Mandating ground contact units be tested for radon, protecting Ontario tenants.

    2. Building Code Amendments - Making changes to the building code to better protect home owners from the dangers of radon.

    “We know government wants to do the right thing, so we urge them to make sure that people like Virginia are protected from the dangers of radon,” said Alan Whitehead. “These two opportunities to save lives and protect Ontarians’ lung health are already on the table. What is needed now is leadership; leadership to bring these options to life through legislation and/or regulations.”

    You have probably heard the old saying “She/he has lung cancer? How is that possible? They never smoked a day in their life.”  This describes Virginia.  She is a non-smoker who gets enough exercise and has done everything right with respect to her lung health. The last thing she expected was to hear from her doctor that she had lung cancer.

    Please take a minute to listen to her tell her story in this short video.

    Backgrounder and facts:

    1. Radon enters buildings through contact with the ground.  In our well-sealed buildings it enters faster than it escapes, resulting in elevated levels and an increased health risk.  Any building has the potential for elevated radon levels including workplaces, schools, daycares and homes.

    2. Additionally, Health Canada warns that the risk to smokers is higher.  Combined effects of smoking and high radon levels can mean a smoker’s risk of developing lung cancer increases from 12% to 33%.

    3. Public Health Ontario confirms that Radon is an important contributor to lung cancer deaths in Ontario, and installing effective radon-preventative measures into buildings may be a good alternative population prevention strategy and testing and remediation may also prevent a portion of radon-related lung cancer deaths.

    4. Radon, as we have learned from TV stars Mike Holmes Sr. and Mike Holmes Jr. through their public service announcements, is an odourless and colourless radioactive gas that attacks our lung tissue.  This can and does lead to lung cancer.

    President's Message -March 2017 

    It’s already March, and the 2017 CARST Conference is fast approaching.  This year, along with the Annual General Meeting, we’ll have new appointments to CARST’s Board of Directors.  With that in mind, we’d like to take a moment to highlight the work of our two outgoing Directors.

    Michel Deschamps is one of the pioneers of radon measurement in Canada.  A founding member of CARST, he has sat on the Board of Directors since our inaugural meeting in 2010.  As a physicist experienced in radiation protection, he brought a scientific insight to the board.  As a French-speaking Quebecer, Michel also helped connect with CARST’s Quebec membership and spent countless hours translating documents and advocating for measurement professionals across the country.  Michel was Treasurer of the Board of Directors, and a valuable member of the CARST/C-NRPP Education Committee; providing valuable input as part of our course review team.  Michel provided great enthusiasm and support in the early days of starting CARST, which was a much-needed attitude. We all enjoyed Michel’s humour and insight and his contribution to CARST’s growth and development is greatly appreciated.

    Steve Mahoney was elected to the CARST Board of Directors at our annual conference in Winnipeg in 2013. His extensive political and public service experience at both the federal and provincial levels has been invaluable in helping CARST develop strategies to advocate for legislative change to building and labour codes. As the former President & CEO of the Canadian Radiation Safety Institute, Steve passionately campaigned to raise radon awareness in the workplace and successfully engaged a number of trade unions, most notably the Boilermakers, who are now strong radon advocates and generous supporters of CARST. The board will miss Steve’s contribution at our monthly meetings, along with his wit and wise counsel; not to mention his keen Irish sense of humour.

    As Michel and Steve step down, the Board of Directors looks forward to welcoming new members.  We had a great response to the call for nominations, and CARST members will have their pick among several highly-qualified candidates who have offered to bring a wealth of experience to work on CARST’s behalf.

    Involvement in CARST doesn’t end with the Board of Directors, however. We have several committees; each dedicated to putting CARST’s goals into action. Consider joining a CARST committee:

    • The Membership Committee is currently working on some changes that could bring many new faces to CARST.  An increased membership means increased benefits for all CARST members.  Join up and see how you can help!
    • Education Committee: are you passionate about keeping the standards for radon education high?  With every radon test and mitigation CARST members perform, we strive to maintain the highest standards in accuracy and radon reduction.  At the same time, we educate one more Canadian family.  Why not join the Education Committee and help to ensure that our education courses continue to push us to excellence?
    • The 2017 CARST Conference may be just around the corner in beautiful Banff, but we’ve already got some ideas brewing for the 2018 Conference.  The 2018 Conference Committee will need new ideas and fresh energy.  Why not join up and help put your own spin on another great event? 
    • C-NRPP Policy Advisory Board: Help shape the policies that govern the C-NRPP program.  As we strive for increased professionalism in the radon industry, we develop new policies to maintain the highest caliber of certified professionals.
    • Public Awareness Committee: New this year!  Do you have experience in marketing and public awareness?  Would you like to help CARST solidify our position as the radon authority in Canada?  If so, please sign up now and help this brand-new committee get up and running!

    Arthur G. Scott Achievement Award

    Finally, as many of you already know, the Canadian radon industry lost a founding father last September with the passing of Arthur G. Scott.  Arthur was a pioneer; developing soil depressurization systems and laying the groundwork for much of the work we do today.  In honour of his life’s work, CARST is pleased to be awarding the Arthur G. Scott Achievement Award for contributions to the radon industry.  The inaugural award will be presented at this year’s conference in Banff, and we ask that you send us your nominations for this award by March 31st at the latest.  As the name of the award suggests, nominees should be individuals who have made significant contributions to the radon industry in Canada.

    Radon awareness in Canada is growing, and CARST needs to grow as well if we’re to achieve our main goal of protecting Canadians.  Some exciting changes are coming to CARST as we adapt to meet the current needs of the radon industry.  It’s a challenging and important time, and we need your enthusiasm and involvement.  Don’t hesitate to step forward and participate!  Email us or drop by and see us in Banff!

    Planning your Travel?  Banff is a Unique Destination!

    Majestic, picturesque and breathtaking; the Rocky Mountains are really a destination like no other.   Banff is a wonderful, quaint mountain resort town that must be experienced to be appreciated.  If you have never been to Banff this is a great opportunity to discover a national treasure.  If you have been to Banff, then surely you don’t need a reminder of why you want to return.  As an added bonus, all National Parks are providing free entry this year to celebrate Canada’s 150th Birthday!

    A unique destination requires unique planning.


    The low Canadian dollar means that we expect a large number of American visitors, so make sure you book your hotel room soon!  The conference is being held at the Banff Centre.  Nestled on the side of Tunnel Mountain on 43 serene acres, this is not your standard hotel.  You won't find the centre on any online booking service, as they book only through their reservation service and rooms are only open to those attending conferences at their facility.  All guests enjoy property-wide WIFI, parking, admission to the Banff Centre's Walter Philips Gallery, and PLUS membership at their fitness and recreation facilities.  Let's face it, Banff has lots of options in hotel room, and we booked a smaller block of rooms this year, so if you want to get into the Conference Hotel, book now!  (Conference rate ends March 21, but we don't expect the rooms to last that long.)

    Book your room reservation here at the Banff Centre.

    Air Travel: 

    If you are planning on flying to the conference, you'll land at the Calgary International Airport. All of Canada's national airlines and many international airlines fly into Calgary.  The international section has just been renovated and this is one of the nicest airports in Canada!

    From the Calgary Airport you'll need to rent a car or take a shuttle bus 150 km (90 miles) to Banff.  Make sure you factor in the travel time between Banff and Calgary when you book your flights.
