“…These two systems passed comparison programs on radioactive waste radioactivity measurements organized in Taiwan in 2009 and 2015 [3] [4]. The aim of this article is to discuss the difference of radioactivity analyses in various scenarios containing reference drums with homogeneous radioactivity distribution, waste drums with radioactivity similar to non-metal drums with homogeneous radioactivity distribution and metal drums with non-homogeneous radioactivity distribution, different filling ratios of whole-drum materials by using these two measurement systems.…”

Two measurement systems, one being comprised of three HPGe detectors and the other being a 4π measurement system of the assembly of 10 sets of scintillation detectors, were compared for their measurement performance in operations of radioactive waste drum radioactivity measurement and clearance and release operation of decommissioning. The system features of the former were high costs, capable of identifying radionuclides, a measurement time of about 1000 sec. The system features of the latter were high sensibility, capable of identifying hotspots, a measurement time of about 100 sec. Various comparisons were made for the differences of the two systems on reference drums, whole-drum homogeneous and non-homogeneous metal drums and non-metal drums, whole-drums of different filling rates. The aim was to compare the differences of the two measurement systems in measuring radioactivity of critical radionuclides of 137 Cs, 54 Mn and 60 Co.
