5. Monitor radon levels
Radon is a radioactive gas that is odorless and colorless and may be in the soil or water where you live. It can break down into solid radioactive elements and attach to dust particles which can be inhaled into your lungs. It can be found indoors as well as outdoors. Indoor exposure usually consist when the radon enters thru cracks in pipes or foundation. The highest levels can usually be found in basements or crawl spaces. In addition, it can be found in concrete flooring, wallboards, and the water supply. Outdoor exposure usually occurs from soil and rocks and usually does not pose a high risk. According to the EPA, indoor levels are usually around 1.3 picocuries per liter (pCi/L) while outdoor levels are about 0.4 pCi/L. People should take action when levels reach 4.0 pCi/L or higher.
