摘要

The effective dose takes into consideration the amount of absorbed dose received by tissues, individual organs and also organ’s radiosensitivity. This study concentrates on the Commission’s regulations of 1991 and 2007 tagged ICRP 60 and ICRP 103 respectively, and seeks to suggest the better guideline for determination of detriment to patient especially from abdominopelvic computed tomography. With mean totals of 375.0 mSv for the ICRP 60 and 341.3 mSv for the ICRP 103 obtained from abdominopelvic computed tomography involving 20 different patients, a T-test calculated value of 6.716 was obtained and compared with the value in the T-table at 95% confidence limit and 18 degrees of freedom to confirm whether there is a significant difference in both ICRP 60 and 103 recommendations in the determination of the effective dose. Finally, it is concluded that there is a significant difference in the ICRP 60 and ICRP 103 as fewer effective doses are obtained from the ICRP 103 recommendations and this difference verifies that the ICRP 103 is more suitable for the determination of the effective dose.
