Abstract

In this study, we analyzed the effects of radiation exposure, as compared to the hematological parameters change of medical radiation workers and the public. The mean value of all hematological parameters were in the normal range. Eosin mean value of the radiation workers($2.52{\pm}1.79%$) showed that a significantly lower than the control group($2.92{\pm}1.39%$). In the comparison of the results depending on the occupation period, it showed high value that the mean of the radiation workers group WBC, platelet, Lymph, Mono, Baso. Over 20 years of radiation workers WBC, Mono showed low values and less than 10 years of radiation workers mean value of Baso showed low values, there was no statistical significance. In the comparison of the results depending on the 4 years cumulative radiation dose, Over 5.0 mSv of Radiation works RBC($4.61{\pm}0.53$ vs $4.91{\pm}0.38$), Hct($41.51{\pm}4.07$ vs $43.97{\pm}3.40$), Eosin($1.74{\pm}1.14$ vs $2.92{\pm}1.39$) showed low value, it was statistical significance. 0.5~1.0 mSv radiation exposure workers Hb ($13.93{\pm}1.75$) showed a significantly lower value than that of the control group ($14.90{\pm}1.29$).

본 연구는 일개 종합병원 내 방사선 종사자의 피폭선량과 그에 따른 혈액검사를 일반인의 혈액검사결과와 비교하여 방사선피폭의 영향을 분석하였다. 대조군과 방사선 종사자군의 혈액검사 결과 모든 항목 평균 값은 정상범위에 포함되어 있었다. 호산구의 경우 방사선 종사자가($2.52{\pm}1.79%$) 대조군($2.92{\pm}1.39%$)에 비하여 낮으며 유의함을 나타내었다. 방사선 작업 종사기간에 따른 종사자군과 대조군의 혈액학적 검사결과 평균값은 백혈구, 혈소판, 임파구, 단핵구, 호염기구가 전체 평균에서 종사자군이 높은 값을 나타내었고, 20년 이상 종사자에서 대조군에 비하여 백혈구, 단핵구는 낮고, 혈소판은 높은 값을 나타내었으며, 10년 이하 종사자에서 호염기구가 대조군에 비해 낮은 값을 나타내었으나 전체 수치의 통계적 유의성은 없었다. 방사선 종사자의 4년간(2012년~2015년) 누적선량에 따른 검사항목별 평균차이에서 5.0 mSv 초과 종사자가 백혈구 평균값에서 대조군 및 5.0 mSv 이하 피폭군에 비하여 낮은 값을 나타내었고, 적혈구($4.61{\pm}0.53$), 적혈구용적률($41.51{\pm}4.07$) 및 호산구($1.74{\pm}1.14$)는 대조군의 적혈구($4.91{\pm}0.38$), 적혈구용적률($43.97{\pm}3.40$), 호산구($2.92{\pm}1.39$)와 저선량 피폭자의 검사결과에 비하여 유의하게 낮은 값을 나타내었다. 0.5~1.0 mSv 피폭 종사자의 혈색소($13.93{\pm}1.75$)가 대조군($14.90{\pm}1.29$) 및 타 피폭자에 비하여 유의하게 낮은 값을 나타내었다.
