[Radon concentration in living accommodations in the Ukrainian S.S.R. in 1989]
Abstract:
The authors relate the tentative measurement data on radon-222 concentrations in different buildings situated in the Ukrainian bedrock geological region. The mean Rn222 concentration was found to be about 87 Bq/m-3 for single-family buildings and 31 Bq/m-3 for many-story sectional and brick buildings. The maximum concentrations were recorded in one-story adobe houses in the Zaporozhye and Kirovograd Regions (about 500 Bq/m-3), which corresponds to the effective equivalent dose about 40 m3b per year.
