Abstract
Geo-referenced datasets of indoor radon concentrations and radium concentrations in
soil are available for the Republic of Macedonia. However, the indoor 222Rn data are
spatially strongly clustered as the measurements were essentially confined to major
towns and cities. Hence, the estimation of the geographical distribution of 222Rn
concentration based only on the 222Rn data is difficult to be made. On the other hand,
geochemical measurements 226Ra are quite well distributed over the country. Since
226Ra is the source of 222Rn, one may think of using 226Ra as a predictor for 222Rn.
In this paper we present a method for modelling the stochastic dependency of indoor
222Rn of soil 226Ra. The method is new in the area on 222Rn assessment and still needs to
be validated by more case studies.
It must be born in mind that the indoor 222Rn depends, in some cases more strongly, on
controlling factors other than the 226Ra in soil, so that its estimation from 226Ra alone is
inevitably imperfect. The results must therefore be understood as estimates in absence
of other information, and as a motivation to carry out measurements in regions where
the model predicts higher 222Rn levels, but for which no measurements are available so far.
