Radon Air Testing for Home, Business and Industry
Radon in Air (EPA Action Level = 4.0 pCi/L)In New England, the migration of radon up from the soil contributes the largest percent of radon found in the average home. Radon from a groundwater type water supply source, particularly a bedrock (artesian, drilled) well, contributes the next largest percentage of radon in the home.
The EPA has set an advisory "action level" of 4 pCi/L for radon gas in indoor air. While not a mandated health standard, this level is a guideline for people to use in assessing the seriousness of their exposure to radon. Studies show that exposure to radon gas over prolonged periods of time increases the risk of developing lung cancer.
