Radon Testing and Prevention
What is radon?
Radon is a radioactive gas. It is colorless, odorless, tasteless, and chemically inert. Unless
you test for it, there is no way of telling how much is present.
Radon is formed by the natural radioactive decay of uranium in rock, soil, and water.
Naturally existing, low levels of uranium occur widely in Earth's crust. It can be found in
all 50 states. Once produced, radon moves through the ground to the air above. Some
remains below the surface and dissolves in water that collects and flows under the
Radon has a half-life of about four days—half of a given quantity of it breaks down every
four days. When radon undergoes radioactive decay, it emits ionizing radiation in the
form of alpha particles. It also produces short-lived decay products, often called progeny
or daughters, some of which are also radioactive.
Unlike radon, the progeny are not gases and can easily attach to dust and other particles.
Those particles can be transported by air and can also be breathed.
The decay of progeny continues until stable, non-radioactive progeny are formed. At each
step in the decay process, radiation is released.
Sometimes, the term radon is used in a broad sense, referring to radon and its radioactive
progeny all at once. When testing measures radiation from the progeny, rather than radon
itself, the measurements are usually expressed in working level (WL) units. When
radiation from radon is measured directly, the amount is usually expressed in picocuries
per liter of air (pCi/L).
