Radon-222 is the most important and most stable isotope of radon. It has a half-life of only 3.8 days , making radon one of the rarest elements since it decays away so quickly. An important source of natural radiation is radon gas, which seeps continuously from bedrock but can, because of its high density, accumulate in poorly ventilated houses.

Results are presented from a statewide survey that measured annual 222Rn concentrations in over 2000 single-family, owner-occupied homes in New York state. The participants were selected by a random-digit-dialing telephone interview approach developed by Mitofsky-Waksberg which allows inferences to be made from the sample to the statewide population.

and fixed if the radon level is at or above 4 pCi/L, EPA’s national voluntary action level. EPA and the Surgeon General also recommend that schools nationwide be tested for radon. (Exposure to 5 pCi/L of radon-222, or 7.5 pCi/L of radon-220, corresponds to an approximate annual average exposure of 0.02 WL for radon decay products in the home.)

The EPA estimates that nearly 1 out of every 15 homes in the United States has elevated radon levels. Radon is a gas which can seep into our homes.
