“Simple dose models may be useful for preliminary, crude or conservative estimations of doses to the population. However, after the Chernobyl accident experts were faced with the practical task on assessing the most probable/real dose of external and internal exposure in different groups of population. And simplified models were not able to incorporate in and reflect a lot of site specific characteristics (inhomogeneity of contamination, the structure of land use, implementation of the countermeasures (CMs), behaviour of the population, etc.). In connection with this the further steps on development of special dose estimation methods taking into account the features of the Chernobyl contamination were undertaken.

“Description of original approaches on actual implementation of up-to-date information technologies – geoinformation systems (GIS) for estimation of doses to the local population in Bryansk region (Russia) are briefly presented in this paper.”
