Radon gas half-life

WebAs a rule of thumb, each 10,000 pCi/L of radon in water increases its level in indoor air by 1 pCi/L. Inhalation of the radon gas released into the air is much more dangerous than its ingestion with drinking water. In the U.S., the average radon concentration in the surface water is 10 pCi/L but 750 pC/L in well water. WebJan 25, 2024 · Radon is a naturally occurring radioactive gas which may be found in high concentrations in indoor environments, such as homes and workplaces. Radon is one of the leading causes of lung cancer. Radon is estimated to cause between 3% to 14% of all lung cancers in a country, depending on the national average radon level and smoking …
