The purpose of this study is an measurement of the skin dose of a patient by using the OSLD(optically stimulated luminescent dosimeter) under several irradiation conditions of the X-ray beam for diagnostic radiography. The measurements of skin dose were performed for head, chest, and pelvis. And test of reproducibility was carried out at the chest. As a result, we obtained the skin dose at forehead of head to be 1.30 mSv. The skin doses at xiphoid process, breast and apex of the lung of the chest were acquired 0.92, 0.52 and 0.70 mSv, respectively. And we obtained the skin doses at the left pelvis and the right pelvis to be 2.78 and 3.08 mSv, respectively. As for reproducibility, a coefficient of variation was 0.033. The skin doses were exhibited the values corresponding from 1/100 to 1/17 of the dose limit of the public(50 mSv) at the deterministic effect. In order to make accurate measurements of the skin doses for each tube voltage, the measured values have to multiply by the displayed values of reader by a correction factor. The energy response of the OSLD with the tube voltage will be studied in the near future.
