방사선 작업종사자 안전을 위한 실시간 능동형 안전관리 플랫폼과 데이터 수집 디바이스 개발 연구

Abstract

Radiation work always carries the risk of radiation exposure, so regulatory agencies manage it throughlicensing when high exposure is expected. However, due to passive management methods using TLD, etc., thereare cases where risk management is done after an incident occurs or the incident is covered up. In this study, wedeveloped a system to manage the location of radiation work and the risk of workers in real time through a safetymanagement platform and a location-based personal dosimeter. The safety platform server receives data from thedeveloped personal dosimeter in real time and manages risks in three steps for each worker using location and doserate, and can predict risks and generate alarms in real time. The personal dosimeter transmits the location and doserate of the worker in real time using GPS and LTE communication. The developed safety management platform andpersonal dosimeter were verified through a field test to receive real-time data of the location and dose rate data of theworker, and the risk management function according to the individual dose rate was verified.
