  1. Recent Swedish experiences in 222Rn control.

    Article - En anglais

    Swedish local authorities are responsible for decreasing 222Rn progeny concentrations in homes in their municipalities.

    To obtain an overall view of their experiences, concerned national authorities sent a questionnaire in 1986 to local authorities.

    One result of the survey was an enhanced interest in the Rn problem among Swedish politicians and the mass media.

    This increased attention resulted in new plans for continued work to decrease Rn levels indoors using 1987-1989, on both a national and a local level.

    The experiences of the local authorities show that Rn progeny concentrations decreased to below the design level in 95% of newly built houses investigated.

    It was also found that Rn progeny concentrations were below the limit for reconstruction in 53% of existing homes that previously had levels exceeding the limit.
