For five years from 2015 to 2019, the cumulative personal exposure dose of radiationworkers and radiation workers across the country was measured to analyze frequency, comparethe average number of radiation workers and radiation workers by year, quarter, age, gender,occupation, radiation workers and radiation workers, and the average number of radiationworkers. It was followed by 2016, 2019, 2018, and 2015. But the year-to-year trend is not visible. In the case of the quarterly average exposure dose, surface dose and heart dose were high in thesecond and third quarters, and low in the first and fourth quarters, but there was no quarterlytrend. Comparing the annual exposure dose by gender and the quarterly exposure dose bygender, it was found that men were received significantly more exposed than women. Comparingthe annual exposure dose by age, the average exposure dose of radiation-related workers overfive years increased with lower age. Comparing the annual exposure dose of each occupationalcategory was analyzed by occupational category, radiologists, nursing staff, doctors, other(research researchers, assistants), dental hygienists, and dentists were shown in the order. Whenthe average exposure dose by radiation-related workers, radiation workers, and others wasanalyzed in quartiles, radiation-related workers and radiation workers were found to be higherthan others. Furthermore, since stochastic effects may occur with long-term exposure to low levelradiation, individual exposure dose data was thoroughly managed and the principle of As Low asReasonably Achievable (ALARA) was implemented when establishing the design of this study.
