Radon Activity Radon impacts on the lungs Lost miners and millers in communities due to radon exposure Radon continues to be an issue

Radon Odorless, colorless Radon in air is ubiquitous Found in outdoor air and indoor air of buildings of all kinds No known safe level of radon

Radon (cont.) Red alert - radon level above 4 pCi/L (pico Curies per Liter) Yellow alert - radon levels between 2 pCi/L and 4 pCi/L Average radon indoor air is about 1.3 pCi/L

op Radon “Daughters” Radon, Polonium, Lead, Bismuth, and Polonium have short half-lives Results in several exposures in a short time

Radon in Lungs Radon or decay products inhaled Particles irradiate lungs Irradiation can cause lung cancer Cigarette smoking synergistic impact Radon

Radon in Buildings From the soil Lower parts of building at greatest risk “Stack effect”

Radon Testing

Radon Mitigation
