The Radon Reduction Sweepstakes is a Canada-wide contest run by Take Action on Radon (TAOR) in conjunction with the Canadian Association of Radon Scientists and Technologists (CARST). The contest provides 10 prizes of up to $1,000 each to homeowners who have tested their home for radon and used a C-NRPP professional to reduce levels to below Canada’s recommended guideline of 200 Bq/m3. A key part of TAOR’s mandate is to encourage Canadians to take action on radon, and the Sweepstakes does just that with the possibility of a cash reward.
Analyzing the data from figure 1 reveals that C-NRPP professionals reduced radon levels to below 100 Bq/m3 over 93% of the time, and to below 50 Bq/m3 80% of the time. These levels are well below Canada’s action level. The remaining 7% of homes were also lowered to below Canada’s action level of 200 Bq/m3
.
Analyzing the cost data, it is apparent that although there is a large disparity between the highest and lowest cost of radon mitigation systems installed, there is good consistency among the average cost of systems between provinces.

About the Sweepstakes
The Sweepstakes is an excellent source of actual mitigation effectiveness and cost data and compelling testimonials from participants. Being able to reference actual numbers when estimating the cost of a radon mitigation system is very helpful, both to homeowners and to policymakers. The data comparing the pre- and post- mitigation radon levels in homes mitigated by certified professionals shows that they are routinely reducing radon levels to well below both Health Canada and the World Health Organization’s guidelines.
