To evaluate detection characteristics by means of an analysis of γ-ray spectra, it is necessary to set a probability distribution for the number of counts that contains their mathematical expectation. In measurements, the mathematical expectation is

It is found that in the presence of several barriers the emanation of radionuclides from a sunken object always has a maximum as a function of time. Its position depends on the time constant of radionuclide emanation from the fuel elements and the tr

The concept of the rate of transport of exchange and non-exchange forms of radionuclides over river catchment is introduced. On this basis, a differential transport equation is proposed for finding the radionuclide content in soil and radionuclide fl
