ABSTRACT
Indoor radon levels were measured in 221 homes in rented accommodation. In addition, buildings were registered for a
series of variables describing building characteristics and used materials. The mean year value
of the indoor radon level
was 30.7 (1~250) Bq/m3.
The indoor radon level exceeded 100 Bq/m3 in 5.9% of the homes. Of the
investigated variables, only homes in
single-family terraced houses, were statistically significant. Approx. 75% of homes exceeding
100 Bq/m3 indoor radon level had levels between 100 and 200 Bq/m3 and 25% had indoor radon
levels exceeding 200 Bq/m3. Significant differences in indoor radon
levels were found in homes located in multi-occupant houses. Additionally, the
risk of indoor radon levels exceeding 100 Bq/m3 in homes in
multi-occupant houses was found to be very low, but the risk was the highest on the
ground floor in a building constructed with slab on ground.
