Understand your risk from elevated radon exposure
Radon Level (Bq/m3) Health RISK
150 Bq/m3 Equals 200 chest x-rays per year
8 cigarettes per day
300 Bq/m3 Equals 400 chest x-rays per year
16 cigarettes per day
375 Bq/m3 Equals 500 chest x-rays per year
20 cigarettes per day
560 Bq/m3 Equals 750 chest x-rays per year
30 cigarettes per day
750 Bq/m3 Equals 1000 chest x-rays per year
40 cigarettes per day
1500 B/m3 Equals 2000 chest x-rays per year
80 cigarettes per day
3750 Bq/m3 Equals 5000 chest x-rays per year
200 cigarettes per day
Health Canada's RADON Action Guideline = 200 Bq/m3
Health Canada recommendations for mitigation are as follows:
-
radon levels between 200 Bq/m3 and 600 Bq/m3 should be mitigated within two years
-
radon levels above 600 Bq/m3 should be mitigated within one year
