摘要

In interventional radiology (IR) procedures, radiation doses received by both patient and staff are relatively high. The objectives of the study are: (1) determine/measure entrance surface dose (ESD) to patient using nanoDot optically stimulated luminescence (OSL) dosimeter, (2) verify that patient doses do not exceed established international guidance levels set by IAEA and ICRP Report 103, as stated in the BSS, applied in the Philippines, (3) estimate the effective dose E to operator and using InLight OSL dosimeters, (4) estimate the annual effective dose E for the operator and staff performing interventional cerebral angiography procedure, (5) determine who among the staff have training in radiation protection in interventional radiology/cardiology, and if so, if such training is applied in practice, and (6) verify that staff doses do not exceed established dose limits set by the IAEA and ICRP Report 103, as stated in the BSS, applied in the Philippines. Clinical data and technical factors were gathered from interventional cerebral angiography procedures (4-vessel angiogram/6-vessel angiogram) performed at the University of Santo Tomas Hospital (USTH). It was found that none of the ESD values approach the dose thresholds for induced skin injuries (erythema or epilation). The estimated weighted annual dose for all the interventional medical workers is 5.9 mSv which is lower than the dose limit given by the IAEA and ICRP Report 103, as stated in the BSS. However, the primary operator has exceeded the investigation level of 30% of the annual dose limit of 20 mSv (13.44 mSv in the case of research badge #3). The computation of the annual dose for this study was based on a survey for the maximum number of IR procedures performed per year.
