Status of routine monitoring methods for internal radiation contamination of transuranic nuclides in urine
For the purpose of radiation protection, individual monitoring of internal exposure provides the nec-essary means to protect occupational safety and health of nuclear workers. The most commonly used methods for routine monitoring of transuranic nuclides are in vitro measurements of those concentration in urine sam-ples. Due to the interference from complex matrix and extremely low emission of transuranic nuclides in urine, accurate measurement of ultra-low level of transuranic nuclides in urine remains a major bottleneck. In this pa-per, the routine monitoring methods of transuranic nuclides for internal radiation contamination was investiga-ted, and the difficulties and bottlenecks were pointed out in view of the research progress of radiochemical a-nalysis methods and measurement techniques.
