Abstract
Among various types of radiation practices, industrial radiography is one of the highest risk activities due to handling high activity sources. Thus, the exposure control of the radiographers is of great importance in this regard. In this study, while presenting the occupational exposure situation of this group in the period from the years 2007 to 2016 in Iran, the effectiveness of the measures taken for the workers who received doses higher than the investigation level has been evaluated. Moreover, a comparison between the averaged individual and collective doses of this radiation practice in Iran with those of some other similar counties has been performed. The results show that all the interventional actions in the field of optimization of protection have been significantly effective. However, to achieve a better level of radiological safety, establishment of a dose constraint can have a significant effect on the further and continuous reduction of this radiation practice
