CNSC follow-up response to a letter to the editor in the Chronicle Herald

Setting the record straight

Dr. Nancy Covington’s rebuttal to my response regarding uranium mining forces me to set the record straight. I would expect a medical professional to be better informed before making such false and inaccurate statements.

Dr. Covington contends that radon levels in the environment increase as a result of uranium exploration. In the open air, the concentration of radon gas is very small and does not pose a health risk. It dissipates rapidly and does not “flow downhill, accumulating in people’s homes” as Dr. Covington suggests. Studies have shown that uranium mining activities do not increase radon levels in the environment away from a mine site and that the level of radon near uranium mines is similar to natural radon levels monitored in background locations.
