이 연구의 목적은 일반방사선촬영에서 입사표면선량에 대하여 나노도트선량계의 측정값과 Non Dosimeter Dosimetry-Method(NDD-M)의 계산값과 비교 평가하는 데 있다. 입사표면선량들의 측정과 계산은 두부(AP), 복부 (AP), 골반(AP), 흉추(AP)와 요추(AP)에 대하여 수행하였다. 결과로서, 계산값에 대한 측정값의 상대비들은 각 부위에 대하여 1.5-2.1을 얻었다. 재현성은 변동계수로서 0.035를 얻었다. The purpose of this study is an assessment between the measured value of the nanoDot dosimeter and the calculated value of Non Dosimeter Dosimetry-Method(NDD-M) for entrance surface dose in general radiography. Measurement and calculation of the entrance surface doses were performed for head(AP), abdomen(AP), pelvis(AP), thoracic spine(AP) and lumbar spine(AP). As a result, the relative ratios of the measured value to the calculated value were acquired 1.5-2.1 for each region. Reproducibility acquired 0.035 as a coefficient of variation.
