Depth profiles of absorbed gamma dose were obtained by numeric calcula
tions in the frame of the model proposed. The radionuclide composition
, characteristic for polluted regions in the town of Pripyat, as well
as specific geometry of sample location were used on model calculation
s. The results obtained proved good shielding characteristics of main
building materials and correlate closely with the data obtained by exp
erimental methods of retrospective accident dosimetry.
