| 目的 了解江西省核医学工作人员甲状腺131I内照射现状。方法 采取普查的方法,于2022—2023年对江西省开展131I治疗相关的工作人员共211人次,采用体外直接测量法测量甲状腺131I活度,并估算待积有效剂量。结果 江西省2022年检出甲状腺131I人员14人,活度为121.32~2 859.09 Bq,其中4人待积有效剂量>2 mSv;2023年检出甲状腺131I人员21人,活度为81.75~1 482.21 Bq,其中10人待积有效剂量>2 mSv;甲状腺131I检出率、检出活度和待积有效剂量两年之间的差异均无统计学意义(P>0.05)。检出率最高的为保洁人员,不同岗位之间的差异无统计学意义(P>0.05)。仅开展甲亢治疗与同时开展甲亢和甲状腺癌治疗131I检出率的差异无统计学意义(P>0.05)。结论 核医学工作人员内照射问题应受到关注,需进一步深入开展内照射监测工作,同时建议医院加强核医学工作场所的放射防护管理。 |

| 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. |
