蚌埠市2004～2007年放射工作人员个人剂量监测结果分析

目的掌握蚌埠市放射工作人员外照射个人剂量动态水平，为放射工作场所的安全防护以及职业人员的健康监护提供依据。方法于2004～2007年以蚌埠市放射工作人员为研究对象，采用热释光法监测，使用Excel等计算机程序对本地区的个人剂量数据分年度进行统计分析。结果4年总体人均剂量当量为2．321msv／a；年剂量当量〈5msv的人员占监测人员的87．28％。工业X线探伤工作人员的4年平均人均年有效剂量最高，为2．617mSv／a，医用X线诊断人数占放射工作人员的80．98％，人均年剂量当量为乡镇、县级医院高于省、市级医院，差异均有显著性。结论蚌埠市大部分放射工作人员的工作环境是安全的，今后要加强对乡镇卫生院和工业X线探伤防护的监督监测。
