Now Is the Time to Test Your Home for Radon Gas

Nearly 40 percent of Idaho homes tested for radon have higher than recommended levels, according to the Idaho Department of Health and Welfare.The naturally occurring radioactive gas is the second leading cause of lung cancer, following smoking.

"Radon is a naturally occurring gas and it's created by the uranium that you would find from the soil, so uranium is normally associated with mountains which is why some states like Colorado would be considered to have more radon," explained Colby Adams, who is the environmental health director for the Idaho Department of Health and Welfare's Division of Public Health. "In Idaho, essentially what has happened over time the radon in the mountains has washed away and eroded and it's settled in different areas of the basin."
