    Article - En anglais

    . The risk from environmental radon levels is not higher now than in the past, when residential exposures were not considered to be a significant health hazard. . The majority of the radon dose is not from radon itself, but from short-lived alpha-emitting radon daughters, most notably 218Po (T1/2 3 min) and 214Po (T1/2 0.164 msec) along with beta particles from 214Bi (T1/2 19.7 min). . Radon gas can penetrate homes from many sources and in various fashions.

    Measuring radon in homes is simple and relatively inexpensive and may be accomplished in a variety of ways.

    Although it is not possible to radon-proof a house, it is possible to reduce the level.
