Abstract:
Decommissioning of nuclear building structures usually leads to large amounts of low-level radioactive waste. Using a reliable method to determine the contamination depth, it is indispensable prior to the start of decontamination works and for minimising the radioactive waste volume and the total workload. This paper deals with the possibilities of determination of depth distribution of activity of 137Cs and depth of contamination. The method described in this paper is based on concrete core sampling and laboratory gamma-ray spectroscopy measurements.
