Abstract

Occupational exposures in conventional and interventional radiology were investigated over a period of 10 years for all radiation workers. The statistical analysis carried out on the refined data showed that the average annual effective doses in conventional and interventional radiology were 0.28 and 0.59 mSv for measurably exposed workers and 0.18 and 0.52 mSv for all monitored workers in 2014. More than 99.9 and 82.8% of radiation workers in conventional and interventional radiology received annual doses less than the public dose limit (1 mSv) in 2014. Comparing the occupational dose levels of different countries (including Iran) in conventional as well as interventional radiology showed a poor comparability among them. Regarding the doses above the investigation level, the analysis showed that majority of them were due to improper use of personal dosimeters (false doses) and only 0.01 and 0.12% of the dose records actually crossed the level in conventional and interventional radiology in 2014.

摘要

在10年的时间里，对所有放射工作人员在传统放射学和介入放射学中的职业照射情况进行了调查。对精炼后的数据进行的统计分析表明，2014年，在传统放射学和介入放射学中，可测量暴露工作人员的年平均有效剂量分别为0.28 mSv和0.59 mSv，所有受监测工作人员的年平均有效剂量分别为0.18 mSv和0.52 mSv。2014年，传统放射学和介入放射学中分别有超过99.9%和82.8%的放射工作人员接受的年剂量低于公众剂量限值（1 mSv）。比较不同国家（包括伊朗）在传统放射学和介入放射学中的职业剂量水平发现，它们之间的可比性较差。关于高于调查水平的剂量，分析表明，其中大部分是由于个人剂量计使用不当（假剂量）所致，2014年在传统放射学和介入放射学中，实际超过该水平的剂量记录仅分别为0.01%和0.12%。
