Abstract:
Objective:To understand the current status of thyroid 131I internal exposure of nuclear medicine staff in Jiangxi province and analyze its influencing factors. Methods:An survey was conducted for the years 2022 to 2023, involving 211 nuclear medicine staff who had received 131I treatment in Jiangxi province. The 131I activity in thyroid was measured by in vitro monitoring measurement, and the committed effective dose was estimated. Results:In 2022, 14 nuclear medicine staff were detected to have 131I in thyroid, with activities ranging from 121.32 to 2 859.09 Bq, including four staff who were estimated to have received committed effective doses above 2 mSv. In 2023, there were 21 nuclear medicine staff who were detected to have 131I in thyroid, with activities ranging from 81.75 to 1 482.21 Bq, in which 10 staff were estimated to have the committed effective dose above 2 mSv. There were no statistically significant differences between the two years in detection rate, measured activity, and committed effective dose to thyroid from 131I ( P>0.05). The highest valure of detection rate was found in cleaning staff, and there were no statistically significant differences between different position types ( P>0.05). There was no statistically significant difference in the detection rate of 131I between those who only have received hyperthyroidism treatment and those who have received both hyperthyroidism and thyroid cancer treatment ( P>0.05). Conclusions:The issue of internal exposure of nuclear medicine staff should receive attention. It is necessary to further carry out internal exposure monitoring. Meanwhile, it is suggested that the management of radiation protection should be strengthened in nuclear medicine workplaces on the part of hospitals.
