The exposure of the public to radon and its daughters in housing is an additional exposure of the natural radiation source to the public. According to its controllable degree, the housing is divided into built and newly built two categories, respectively, given the concentration of radon and its progeny control standards. This standard has been implemented since July 1, 1996.
