일반병원과 치과병원과의 방사선 관계종사자 피폭선량 비교분석

Abstract

Research and investigation is required for the exposure dose of radiation workers towork in the dental hospital as increasing interest in exposure dose of the dental hospital recentlyaccordingly, study aim to minimize radiation exposure by making a follow-up study of individualexposure doses of radiation workers, analyzing the status on individual radiation exposuremanagement, prediction the radiation disability risk levels by radiation, and alerting the workersto the danger of radiation exposure. Especially given the changes in the dental hospital radiationsafety awareness conducted the study in order to minimize radiation exposure. This studyperformed analyses by a comparison between general and dental hospital, comparing eachoccupation, with the 116,220 exposure dose data by quarter and year of 5,811 subjects at generaland dental hospital across South Korea from January 1, 2008 through December 31, 2012. Thefollowing are the results obtained by analyzing average values year and quarter. In term ofhospital, average doses were significantly higer in general hospitals than detal ones. In terms ofjob, average doses were higher in radiological technologists the other workes. Especially, theyshowed statistically significant differences between radiological technologists than dentists. Theabove-mentioned results indicate that radiation workers were exposed to radiation for the past5 years to the extent not exceeding the dose limit (maximum 50 mSv y-1). The limitation of thisstudy is that radiation workers before 2008 were excluded from the study. Objective evaluationstandards did not apply to the work circumstance or condition of each hospital. Therefore, it isdeemed necessary to work out analysis criteria that will be used as objective evaluation standard. It will be necessary to study radiation exposure in more precise ways on the basis of objectiveanalysis standard in the furture. Should try to minimize the radiation individual dose of radiationworkers.
