A Study on the Introduction of Dose Constraints for Occupational Exposures: Focusing onExperts’ Opinions by Field of Radiation Industry. The International Commission on Radiological Protectionsuggests Justification, Optimization, and Dose Limits as the three principles of radiological protection,among which, as a means of protection optimization, ICRP 103 recommends to set dose constraints. Inthis study, opinions are collected from experts in each category of radiation industries for stakeholderparticipation to qualify dose constraints. A guidance and questionnaire for analyzing the dose constraintshave been developed for their collection, and opinions were collected from radiation protection expertsin selected categories. 20 out of 22 experts, consisted with 91%, have assessed the dose constraintssetting is necessary, and 2 experts, consisted with 9%, assessed it is unnecessary. The average of doseconstraint presented by experts for RI production institutions is to be the highest level of 15.3 mSv, andlight-water reactors (14.6 mSv), non-destructive inspection (14.4 mSv), heavy-water reactor and medicalinstitutes (13.9 mSv) is to be above the overall average dose constraint. In case of public institutions, theaverage dose constraint is to be 8.6 mSv, and research institutions (8.8 mSv), educational institutions (9.6mSv), waste disposal sites (9.7 mSv), and general industries (10.6 mSv) are resulted to below the overallaverage dose constraint. As for the means of setting dose constraints, 8 experts out of 22 suggestedsetting dose constraints for each specific industry or task. And, 5 experts especially suggest settingdose constraints for the specific groups with relatively high exposure, such as workers with above therecord levels. As a countermeasure for workers who exceed the dose constraints, 15 experts out of 22expressed that the cause analyses for them and preparation for a plan of reducing them are necessary.
