The major human health problem related to radon accumulation is
Radon and its decay products are the major contributors to human exposure from natural radiation sources. ... However, the problem of the health effect of radon ...For that reason, the term “radon” identifies mainly the 222 Rn and this is the convention followed thereafter. Radon ( 222 Rn) is released primarily from soil and approximately 10% of it is released into the atmosphere ( 3, 4 ). 218 Po, 214 Pb, and 214 Bi are radon’s most significant progeny in terms of radiation dose.This radiation can damage lung cells and eventually lead to lung cancer. Cigarette smoking is by far the most common cause of lung cancer in the United States, but radon is the second leading cause. Scientists estimate that about 20,000 lung cancer deaths per year in the US are related to radon.

Radon is a gas that you cannot smell, taste, or see. Radon forms naturally when uranium, radium, and thorium break down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes. Breathing in radon can cause health problems.Radon is produced as the metal radium naturally decays. Radium is a naturally-occurring element, made as the elements uranium and thorium decay into lead. Radon gas emissions from bedrock and soil vary greatly based on the local geology. Radon is an inert, colorless, odorless, and tasteless gas. It doesn’t react with other elements.The only established human health effect currently associated with residential radon exposure is lung cancer.
