Radon Gas: Indoor Air Quality Carolina Mann Main Public Health & Social Justice PHE /2/08

Background Info Radon is formed from the decay of Uranium. It is found in ground water and indoor air Radon is a radioactive gas that is odorless, invisible, and tasteless. You are at risk when your home measures at more than 4 pCi/L. USGS, US Geological Survey 6/21/ retrieved 11/6/2008www.usgs.gov/newsroom

Whos at Risk? Energy Efficient Homes Homes with basements Homes with cracked foundations Buildings with poor ventilation Homes with poor insulation

Worldwide Sweden China Spain W. Germany Netherlands United States To name a few countries.

Risk Radon exposure is second leading cause of lung cancer Second to smoking Smokers and ex-smokers are at 5 times greater risk than life-long non-smokers Connection made from studying miners Length of time of exposure Diagnosed through CT scans

Regulations The US government does not have any regulations regarding private residence radon exposure No regulations for public indoor air quality Policies are piecemealed together based on complaints

WHO Radon Meeting March 2008 Working on international framework to guide governments in creating regulations on construction and existing construction measurements to be taken when buying and selling homes
