They emit Radon-222 and Thoron (Radon-220) but only 0.1 - 0.3 pCi/L each in a typical basement. The very short half-life of Thoron (96 seconds) reduces its typical concentration in homes to 0.3 pCi/L.

Typically, when we speak of radon, we are speaking of radon 222 which has an half life of 3.8 days. This means that if a volume of radon is sealed into a container and left on its own, half of the radon will decay into SLRDs and be gone in four days. it was assumed that drafty houses would have less radon than "tight" houses. Your home traps radon inside, where radon levels can build up. Any home may have radon problems. This means new and old homes, well-sealed and drafty homes, and homes with or without basements.
