응급센터에 근무하는 의사의 방사선 피폭에 관한 연구 = Radiation Exposure to Physicians inthe Emergency Department

다국어 초록 (Multilingual Abstract)

Purpose: Emergency physicians (EP) are vulnerable to
radiation exposure while on duty in the emergency department
(ED). Although many studies have been reported
abroad, there have been few studies of radiation exposure
to EP in Korea. This study was performed to determine the
present radiation exposure conditions of EP in Korea.
Methods: A prospective study was conducted from April 1,
2007 to June 30, 2007 at ED in three teaching hospitals.
Eighteen interns and 19 residents were selected. Each
wore thermoluminescent personal radiation dosimetry monitors
at near the thyroid while working in the ED. We estimated
the radiation exposure dose of these EP for three
months and compared the results with those obtained for
radiologists.
Results: The average radiation exposure dose of EP over
three months was 0.257±0.391 mSv, and that of radiologists
was 0.184±0.273 mSv. These results were below the
recommended occupational dose limit of 5 mSv per 3
months. The radiation exposure dose of EP was higher
than that of radiologists, but the difference was not statistically
significant (0.280±0.303 vs 0.075±0.981 mSv,
p=0.042).
Conclusion: We recommend that the use of dosimetry by
EP needs to be reviewed. EP should be aware of radiation
exposure risks and minimize radiation exposure.
