Atomic Energy Aims and scope

Abstract

A method is presented for calculating the equivalent dose rate for the interior spaces in enclosures. The method uses the results of remote measurements, performed with a γ locator, of radioactive contamination levels. The spectral characteristics of photon radiation are taken into account. The results of a calculation of the equivalent dose rate in the reactor room of the No. 4 unit of the Chernobyl nuclear power plant, which are based on measurements performed in the fall of 1996, are presented as an example.
