Health Canada printed and distributed a brochure in the Kingston Ontario area… “Radon: Is it in your home” My brother Bill Marston brought this to my attention because it seems alarming.
“Exposure to radon and tobacco use together can significantly increase your risk of lung cancer. For example, if you are a lifetime smoker but are not exposed to radon, your risk of getting lung cancer is one in eight. If you add exposure to a high level of radon, your risk becomes one in three.” According to Bill Marston this is alarmist.
And so according to the

annual radon concentration exceeds 200 Bq/m3 in the normal occupancy area.

**Also the OBC div B part 9…section 184.108.40.206 talks about 3 specific areas in On where Radon 222 might exceed 250millibecquerels per litre of air. If so, then specific construction measures would be mandated. **
Of course you can purchase a test kit, for around $50.00 and in about a week you can receive the results. Unlike water testing, which is free in the Kingston Ontario area these tests cost money. For water, according to Bill Marston, you simply pick a test bottle at 221 Portsmouth, or 181 Barrie St, follow the instructions, take the sample, return the bottle, and the results are returned to you for no cost in about 7-10 days.
Have a great day
