“…Referring to IAEA Standards (IAEA, 2004), Chinese Taipei had developed a guide titled: "Administrative Regulations for Radioactive Waste below Certain Activity or Specific Activity" (ROC, 2004), as a basis for implementing the clearance of radioactive waste. In response to the decommissioning of the Taiwan Research Reactor (TRR), Chinese Taipei established the Clearance Measurement Laboratory, measuring instrument calibration and quality control techniques, radioactive waste drum counting techniques and completed related technical reports (Yuan et al, 2009;Yeh et al, 2012), operation procedures (ROC, 2014b), etc. In the period of 2007-2011, the release operation of 2 278 tonnes of concrete and 140 tonnes of scrap metal had been completed and that demonstrated Chinese Taipei's practical experiences and mature technical capabilities in implementing radioactive waste free release.…”

is a unique forum where the governments of 35 democracies work together to address the economic, social and environmental challenges of globalisation. The OECD is also at the forefront of efforts to understand and to help governments respond to new developments and concerns, such as corporate governance, the information economy and the challenges of an ageing population. The Organisation provides a setting where governments can compare policy experiences, seek answers to common problems, identify good practice and work to coordinate domestic and international policies.

“…The Institute of Nuclear Energy Research (INER) established two gamma radioactivity measurement systems which were respectively comprised of three HPGe detectors and 10 sets of scintillation detectors (4πmeasurement system) [1] [2]. The main critical radionuclides measured by the two systems are 137 Cs, 54 Mn and 60…”

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.
