Individual measurements of dose rate (DR) capacity values were performed on the outer surfaces (roof) of object “Ukryttya”, in local zone both before and after pitching of Arch construction (Arch) as well as study the characteristics of angular distribution of gamma radiation intensity at those areas. A comparative analysis of results obtained was performed. At all measuring points after Arch pitching a reduction of DR value, depending on area of research, was observed.Measurements were being performed during the period from 16.11.2016 till 18.01.2017.
Keywords: object “Ukryttya”, arch construction, device ShD-1 (sphere-detector), dose rate angular distribution, device "Ekran".
