Abstract
[Objective] To observe the personal radiation doses of radiological staff in a cancer hospital in Jiangsu Province,so as to provide reference for the scientific management of radiation protection.[Methods] The occupational exposure doses of radiological staff in a cancer hospital from 2012 to 2016 were analyzed.A total of 1001 person-times were recorded,involving radiodiagnosis,radiotherapy,interventional radiology,and nuclear medicine departments.[Results] In the five years,the annual effective doses were between 0.16 mSv and 0.22 mSv,with an average of 0.18 mSv.All personnel doses were under the limit (20 msy) of Basic standards for protection against ionizing radiation and for the safety of radiation sources (GB 18871-2002).The annual effective doses were significantly different among departments (H=119.39,P＜ 0.01).In descending order,the annum effective dose was found in interventional radiology department (0.51 mSv),nuclear medicine department (0.28 mSv),radiodiagnosis department (0.19 mSv),and radiotherapy department (0.13 mSv).The highest maximum annual effective dose occurred in radiodiagnosis technician (2.73 mSv),and the lowest occurred in nuclear medicine physician (0.38 mSv).The personal annum effective dose of the interventional radiology staff visibly turned up since 2014 (P＜0.01),and was obviously higher than that of the staff of other departments (P＜ 0.01).[Conclusion] The annual average effective doses of selected radiological staff in the cancer hospital are under the limit stipulated by the national standard.Protection management of staff with duty of interventional radiological treatment deserves more attention.关键词
