目的 对呼和浩特地区进行放射卫生监督监测。方法 按照国家标准规定的统一方法。结果 共监测医用诊断X射线机 3 8台 ,3 1台合格 ,合格率为 81.6% ;监测含密封源仪表 13台 ,放射工作人员的外照射个人剂量在安全范围之内 ;监测工业X射线探伤机 14台 ,操作位空气比释动能率为 (6.19± 3 .8) μGy·h-1;监测放射工作人员外照射个人剂量 10 0人次 ,均远小于 5 0mSv的年剂量限值。结论 经过近几年监督监测力度的加大 ,呼和浩特地区的放射卫生防护工作基本符合国家的放射防护相关标准
Objective To monitor the radiation health in Hohhot area. Method in accordance with the provisions of national standards for a unified approach. Results A total of 38 sets of medical diagnostic X-ray machines were detected, with 31.1 pass. The qualified rate was 81.6%. Thirteen units with sealed source were monitored, and the external dose of radiation workers was within the safe range. Monitoring industrial X-ray inspection 14 sets of machines, and the rate of kinetic air kerma (6.19 ± 3 .8) μGy · h-1 at the operation site; and the individual radiation dose of 10 0 for radiation workers was far less than the annual dose limit of 50 mSv. Conclusion After the intensification of surveillance and monitoring in recent years, the radiation protection work in Hohhot basically conforms to the national standards for radiation protection
