Abstract

Fundamental data on the safety status is necessary to develop and operate the additional policies related to the radiation safety, however, few studies have been conducted to investigate the status quantitatively. In this study, out of the areas related to radiation safety, the status of the radiation worker, ambient radiation and the environmental radiation were examined in the quantitative aspect using diverse statistical methods. In the results of that, following information were obtained. First, out of the radiation workers engaged in 9 businesses as of end of 2014, the business having highest exposure dose is NDT showing significantly high than other businesses. Second, the average difference of the exposure doses in radiation workers in 9 businesses in 2014 compared to that in 2010 was not statistically significant at significance level of 5% (p=0.221). Third, the average of the environmental radiation in Gyeonggi-do was high than the Jeollabuk-do. The results of this study are anticipated to assist to utilize the basic data for the workers on radiational works, daily living radiation, and the safety control related to the environmental radiation, and to establish the policy of radiation protection in the future.

방사선 안전과 관련된 추가적인 정책을 수립 운영하기 위해서는 안전현황에 대한 기초적인 자료가 필요한데, 계량적인 관점에서 현황을 고찰한 연구는 많지 않다. 이에 본 연구에서는 방사선 안전과 관련된 영역 중, 방사선작업종사자, 생활 주변방사선 그리고 환경방사선 현황을 중심으로 다양한 통계적인 방법을 활용하여 계량적인 측면에서 고찰하였으며. 그 결과 다음을 알 수 있었다. 첫째, 2014년도 말 기준으로 9개 업종에 종사하는 방사선작업종사자 중 피폭선량이 가장 높은 업종은 NDT로서 다른 업종에 비하여 유의적으로 높게 나타났다. 둘째, 9개 업종의 방사선작업종사자에 대한 2010년 대비 2014년 피폭선량의 평균차이가 유의수준 5%에서 통계적으로 유의하지는 않은 것(p=0.221)으로 나타났다. 셋째, 전라북도 지역에 비하여 경기도 지역의 환경방사선량의 평균이 높은 것으로 나타났다. 본 연구의 결과는 향후 방사선작업종사자, 생활주변방사선, 환경방사선 관련 안전관리를 위한 기초자료로의 활용 및 방사선방호정책의 수립에 도움이 되기를 기대해 본다.
