Gamma-spectrometric control method of activity and nuclide composition of low-active solid radioactive waste

The gamma-spectrometric control method of low-active solid radioactive waste, based on direct measurement of activity and nuclide composition has been developed. The measurements were carried out in the geometry of standard steel container of 200 l. volume, where low-active wastes were placed. To take into account distribution non-homogeneities of solid waste over the geometry measured a special rotating platform was used, the low-active radioactive wastes being placed on it. Metrological certification was performed and the main errors of this method for 95 % of confidence probability were determined
