基于衡阳市放射性医疗检查的剂量调查

Based on the Doses of Radioactive Medical Examination Research in Hengyang

当前,放射性医疗受检者对放射性医疗检查所接收放射性没有足够的认识及相应的重视,导致其年受照剂量可能出现超标现象.因此结合《个人和环境监测用热释光剂量测量系统》,利用热释光法,对衡阳市区部分三甲级医院的X光机对受检者不同体位受照剂量进行调查,为受检者接受放射性检查提供参考.

Nowadays,adverse effect of radioactive medical examination are less recognized by patients and doctors.They don＇t attach enough importance to radioactive medical examination so that their annual dose value of radiation exposure is likely to be out of limitation.Therefor,this article,referring to Thermoluminescence dosimetry system for personal and environmental radiation monitoring,researched different body parts＇ dose value of radiation exposure on different model of medical x-ray machine in some tertiary care hospitals in Heng Yang,which will provide a reference to patients and doctors. The research shows：When patients receive radioactive medical examination,their lumbar spine is exposed to a higher radiation,their limbs are exposed to a lower radiation.
