目的为了解某医院放射卫生防护情况。方法 2012年对某医院螺旋CT、多功能DR、高频胃肠机等X射线装置进行了监测并对该单位12名放射工作人员进行了个人剂量监测。结果机房周围环境监测显示为(0.06～0.18)μGy/h,放射工作人员个人剂量监测显示为(0.69～1.3)mSv。结论该医院机房周围环境监测屏蔽安全防护性能基本符合GB18871-2002的要求,该医院个人剂量监测符合GBZ 128-2002的要求。
Purpose To understand the radiation protection situation in a hospital. Methods In 2012, a X-ray device of a spiral CT, multi-function DR, high-frequency gastrointestinal machine in a hospital was monitored and 12 individual radiation workers in the unit were monitored for their personal dosages. Results The environmental monitoring of the engine room showed (0.06 ~ 0.18) μGy / h, and the personal dose monitoring of radiation workers showed (0.69 ~ 1.3) mSv. Conclusion The safety performance of the environment monitoring shield around the hospital room basically meets the requirements of GB18871-2002. The personal dose monitoring of this hospital meets the requirements of GBZ 128-2002.
