Radon and its daughters are, taken together, often the single largest contributor to an individual's background radiation dose, but due to local differences in geology, [6] the level of exposure to radon gas differs by location. A common source of environmental radon is uranium-containing minerals in the ground; it therefore accumulates in ...
Radon compounds are chemical compounds formed by the element radon (Rn). Radon is a noble gas, i.e. a zero-valence element, and is chemically not very reactive. The 3.8-day half-life of radon-222 makes it useful in physical sciences as a natural tracer. Because radon is a gas under normal circumstances, and its decay-chain parents are not, it ...
To address the more common problem of breathing in radon released from water used during showers and other household activities, a point-of-entry solution may be more reliable. [109] Point-of-entry systems usually involve a granular activated carbon filter, or an aeration system; both methods can help to remove radon before it enters the home's ...
The radon levels in some of the mines can reach 400 to 700 kBq m −3. [17] A common unit of exposure of lung tissue to alpha emitters is the working level month (WLM), this is where the human lungs have been exposed for 170 hours (a typical month worth of work for a miner) to air which has 3.7 kBq of 222 Rn (in
Radon mitigation is any process used to reduce radon gas concentrations in the breathing zones of occupied buildings, or radon from water supplies. Radon is a significant contributor to environmental radioactivity and indoor air pollution. Exposure to radon can cause serious health problems such as lung cancer. [1]

), which is the most common naturally occurring isotope of uranium. It undergoes alpha decay to radon-222, which is also radioactive; the decay chain ultimately terminates at lead-206. Because of its occurrence in the 238 U decay chain, 226 Ra exists naturally at low concentrations in uranium-containing minerals, soil, and groundwater. [3]
