    Abstract

    BACKGROUND:
    With increasing use of medical radiologic procedures, wearing proper protector should be emphasized to reduce occupational radiation exposures. This research describes the rates of lead apron wearing for radiation protection and assessed occupational factors related to wearing rates for various types of healthcare professionals.

    METHODS:
    We conducted a self-administered questionnaire survey through a website, on-site visits, fax, and mail. Of the 13,489 participants, 8858 workers who could not completely separate themselves from radiological procedure areas. Their general characteristics (sex and age), work history (job title, duration of employment, and hospital type), and practices (frequency of radiationprocedures, ability to completely separate from radiation, and frequency of wearing protective lead aprons) were examined.

    RESULTS:
    The mean rate of lead apron wearing during radiologic procedures was 48.0 %. The rate was different according to sex (male: 52.9 %, female: 39.6 %), hospital type (general hospital: 63.0 %, hospital: 51.3 %, clinic: 35.6 %, dental hospital/clinic: 13.3 %, public health center: 22.8 %), and job title (radiologic technologist: 50.3 %, doctor: 70.3 %, dentist/dental hygienist: 15.0 %, nurse/nursing assistant: 64.5 %) (p < 0.001). By logistic regression analysis stratified by job title, use of lead aprons by radiologic technologists and nurses/nursing assistants was associated with hospital type and exposure frequency score. For doctors, apron wearing was associated with employment duration. For dentists/dental hygienists, apron wearing was associated with the exposurefrequency score.

    CONCLUSIONS:
    To improve working environments for healthcare professionals exposed to radiation, it is necessary to consider related factors, such as job title, duration of employment, and hospital type, when utilizing a planning and management system to prevent radiation-related health problems.

    2018년 Radiation Protection Dosimetry 저널에 수록된 본 논문은 의료기관에서 근무 중인 방사선 작업종사자의 피폭선량 평가를 위해 종사자의 작업 특성과 안전 준수 방법에 대한 상관관계를 조사하였음.
    이를 위해 국가 선량 등록 기록부를 참고하여 작업 특성에 따른 방사선 피폭선량이 조사되었고, 다중회귀 분석을 통해 주어진 위험 요소와 작업절차간의 상관관계가 평가되었음. 또한 이를 수치학적으로 평가하기 위해 % 초과 위험도(% excess risk explained)라는 개념이 사용되었음.
    평가 결과 병원에서 일하는 30세 미만의 작업 종자사가 진단 X-선, 휴대용 X-선 및 C-arm을 사용할 경우 가장 높은 수준의 % 초과 위험도가 평가되었고, 여성보다는 남성에게서 약 2배 높은 %초과 위험도가 평가되었음.
