目的确保核医学科同位素应用安全,增强医护人员的防护意识。方法按照国家相关标准对核医学科进行辐射水平监测,并估算操作医护人员的年最大辐射剂量。结果①操作技师累计年最大辐射剂量为1.245 mSv/a②操作护士累计年最大辐射剂量为1.289 mSv/a③操作护士手部位(未戴铅手套)为12.67 mSv/a。结论日常工作必须规范化、制度化,认真准备、熟练操作,合理运用时间、距离、屏蔽三种防护手段,可以降低医护人员的年辐射剂量,保证医护人员的身体健康。
Objective To ensure the safety of isotope application in nuclear medicine department and enhance the protection awareness of medical staff. Methods To monitor the radiation level of the nuclear medicine department according to relevant national standards and to estimate the annual maximum radiation dose of the operating medical personnel. Results ① The accumulated annual maximum radiation dose of operating technicians was 1.245 mSv / a. The cumulative annual maximum radiation dose of operating nurses was 1.289 mSv / a. The operating nurse hand position (without lead gloves) was 12.67 mSv / a. Conclusion Daily work must be standardized, institutionalized, carefully prepared and proficient in operation. Reasonable use of time, distance and shielding means of protection can reduce the annual radiation dose of medical staff and ensure the health of medical staff.
