Abstract
This study is focused on the issues of remediation of sites and territories contaminated with radionuclides as a result of the past activities of the facilities. Actions performed at the territory of the «Mosrentgen» plant, contaminated by 137Cs after the radiation accident in 1962, are evaluated as an example. This paper provides a detailed description of the actions performed in 2012–2017 and the analysis of the mistakes made during the radiation survey, leading to the detection of the large volume of the radioactive wastes during the excavation at the construction of the industrial building at the decontaminated site. The authors propose a method of preliminary assessment of the 137Cs activity concentration in soil based on the gamma-radiation exposure rate on the surface of the soil batch. The results of the study indicate a necessity of development and implementation of the legislative base regulating the structure and types of surveys for remediation of facilities and territories.
