Abstract: For the purpose of radiation protection, individual monitoring of internal exposure provides the necessary 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 samples. 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 paper, the routine monitoring methods of transuranic nuclides for internal radiation contamination was investigated, and the difficulties and bottlenecks were pointed out in view of the research progress of radiochemical analysis methods and measurement techniques.

Key words: transuranic nuclides, internal exposure, routine monitoring, radiochemical analysis method, measurement technology
