The most elaborate case-control epidemiologic radon study performed by R. William Field and colleagues identified a 50% increased lung cancer risk with prolonged radon exposure at the EPA's action level of 4 pCi/L. [77] Iowa has the highest average radon concentrations in the United States and a very stable population which added to the ...
Radon concentrations can vary daily, and accurate radon exposure estimates require long-term average radon measurements in the spaces where an individual spends a significant amount of time. [ 174 ] Radon levels fluctuate naturally, due to factors like transient weather conditions, so an initial test might not be an accurate assessment of a ...
Radon is measured in picocuries per liter of air (pCi/L) or becquerel per cubic meter (Bq m-3). Both are measurements of radioactivity. The World Health Organization (WHO) sets the ideal indoor radon levels at 100 Bq/m-3. [97] In the United States, it is recommend to fix homes with radon levels at or above 4 pCi/L.

The Iowa Radon Lung Cancer Study, which was overseen by Field, is widely considered the most comprehensive residential radon study ever performed. The study [ 3 ] found a 50% increased lung cancer risk at the EPA's radon action level of 4 pCi/L. Field is considered one of the leading advocates in the world for the reduction of radon exposure in ...
Toxic chemicals called PFAS are in pesticides sprayed on food and included in pet flea treatments and home bug repellants, a new study found. Toxic ‘forever chemicals’ found in pesticides used ...
