Coping with radon problem in a private house

摘要

In one of the 50 houses in which, during a national radon survey of 1000 homes in Slovenia, indoor radon concentrations exceeded 1000 Bqm~(-3), radon was further investigated. Except in the attic, elevated radon concentrations were found everywhere in the home, ranging from 0.5 to 12kBqm~(-3). Applying ICRP 65 methodology, an annual effective dose in the range from 9 to 35mSv was estimated for an inhabitant for different exposure scenarios. The radon problem was successfully mitigated and radon concentration reduced below 200 Bq m~(-3).
