Radon is responsible for the majority of public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location. Radon gas from natural sources can accumulate in buildings, especially in confined areas such as attics and basements.
Radium-228 is more likely to cause cancer of the bone as the shorter half-life of radon-220 compared to radon-222 causes the daughter nuclides of radium-228 to deliver a greater dose of alpha radiation to the bones. It also considers the induction of several forms of cancer caused by internal exposure to radium and its daughter nuclides.
Radon gas is a radioactive chemical element that is the largest source of background radiation, about 2mSv per year. [17] This is similar to a head CT (see table). Other sources include cosmic radiation, dissolved uranium and thorium in water, and internal radiation (humans have radioactive potassium-40 and carbon-14 inside their bodies from ...

This was from gold brachytherapy seeds that had held 222 Rn, which were melted down after the radon had decayed. [70] The presence of radon in indoor air was documented as early as 1950. Beginning in the 1970s, research was initiated to address sources of indoor radon, determinants of concentration, health effects, and mitigation approaches.
