A COMPARISON OF OCCUPATIONAL DOSES IN CONVENTIONAL AND INTERVENTIONAL RADIOLOGY IN IRAN.

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.
