Abstract:
Objective:To understand the current situation of occupational internal exposure dose research using direct measurement method in China, and to explore the occupational internal dose level of nuclear medicine staff.Methods:From 2023 to April 2024, search on platforms such as China National Knowledge Infrastructure and Chinese Medical Journal Network, to collect research literature on the internal exposure dose monitoring of nuclear medicine staff and discuss the internal exposure dose assessment method. According to the literature reported thyroid 131I activity level at the measuring time, the internal exposure dose level was estimated using the method recommended by GBZ 129-2016. Results:According to existing research reports on direct measurement using portable γ spectrometers, 6.1% of nuclear medicine workers may receive a 131I dose greater than 1 mSv/a. Conclusion:It is necessary to conduct periodic continuous monitoring for personnel whose internal exposure dose may greater than 1 mSv/a, and it is necessary to explore the feasibility of periodic internal exposure monitoring method carried out by hospitals.
