Radon: Air
built 285 days ago
Radon 222 is a decay product from the U-238 decay chain, illustrated in Fig. 1. The external dose from Rn-222 and its airborne progeny is a very small fraction of the natural external radiation dose received by individuals. However, inhalation of radon and its daughters may be followed by deposition of potentially large amounts of energy, i.e. absorbed dose in the tracheobronchial epithelium from the short-lived a- and b- particle emitting decay products, primarily from Po-218, Pb-214, Bi-214, and Po-214.

Radon emanation from the soil varies with soil type and with surface uranium content, so outdoor radon concentrations can be used to track air masses to a limited degree. This fact has been put to use by some atmospheric scientists.

Radon was sometimes used in hospitals to treat cancer and was produced as needed and delivered in sealed gold needles. Radon is used in hydrologic research, because of it's rapid loss to air. It is ... used in geologic research and to track air masses.

Radon cannot be seen, smelled or tasted, but it exists in the air you breathe. You are likely to gain the most exposure to Radon in your own home, where you spend most of your time.
