The World Health Organization suggests mitigation systems starting at 2.7 pCi/L of radon in the air. The WHO’s recommendations are based on a review of research by 100 scientists from 30 countries.
The International Radon Project (IRP) is a World Health Organization initiative to reduce the lung cancer risk around the world. The IRP released their guidance to member countries in September 2009. [ 1 ]
Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium . [ 2 ] Radium may also be released into the environment by human activity: for example, in improperly discarded products painted with radioluminescent paint.
The School Health Policies and Practices Study (SHPPS), conducted by the CDC in 2012, found that of schools located in counties with high predicted indoor radon levels, only 42.4% had radon testing policies, and a mere 37.5% had policy for radon-resistant new construction practices. [59]
The Boise School District says it found radon in three classrooms at North Junior High School over the winter break. The school district said Thursday that it acted swiftly to ventilate the ...

Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium-40 (a long-lived beta emitter that is part of natural potassium on earth) and any of the products of the ...
Radon is thus assumed to be the second leading cause of lung cancer after smoking, and accounts for 15,000 to 22,000 cancer deaths per year in the US alone. [9] [better source needed] However, the discussion about the opposite experimental results is still going on. [10] About 100,000 Bq/m 3 of radon was found in Stanley Watras's basement in 1984.
