Ongoing research on monitoring of internal exposure of nuclear medical staff / 中华放射医学与防护杂志

ABSTRACT

With the wide application of nuclear medicine and the increase in the number of related staff, the potential occupational health problems should receive enough attention. At present, the personal dose monitoring of most radiation workers in nuclear medicine is mainly based on the information on external exposure provided by thermoluminescence dosimeters whereas the routine internal exposure monitoring has not fully been carried out, thus resulting in underestimating their annual effective dose. Comprehensive personal dose monitoring is not only an important part of occupational health monitoring, but also a crucial means of occupational health management. In this paper, the characteristics of internal exposure in nuclear medicine were analyzed, the monitoring techniques and dose estimating method were introduced, and several commonly used softwares were listed, so as to comprehensively and objectively learn about the current internal radiation exposure of nuclear medicine workers, and to provide reference for health administration departments to formulate regulatory policies and protection requirements.
