摘　　要：内照射污染监测是保障放射工作人员职业安全和健康的必要手段,最常用的方式是测量尿液中的放射性核素。然而,尿液基体复杂,超铀核素进入体内排泄缓慢,如何准确测量尿液中低水平超铀核素含量是个人内照射污染常规监测的难点。本文调研了目前尿液中超铀核素内照射污染常规监测方法,从放射化学分离方法及测量技术的研究方面提出对尿液中超铀核素进行准确测量。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.
