IMPROVED OPERATION METHOD OF NON-DESTRUCTIVE ASSAY FOR OVER-PACK DRUM CONTAINING COMPACTED DRUMS

摘要

The present invention relates to an operation method of a nuclide analysis apparatus, and more specifically, to an operation method of a nuclide analysis apparatus for improving accuracy of nuclide analysis of a multi-embedded drum, which expands a measurement range of an existing drum nuclide analysis apparatus, limited to a single-embedded drum, and selectively uses a projection source medium attenuation compensation method and a multi-efficiency medium attenuation compensation method to evaluate even radionuclide radioactivity of a multi-embedded drum, so that the radionuclide radioactivity of both the single-embedded drum and the multi-embedded drum can be evaluated.
