Abstract

This study was aimed to measure and evaluate the staff and patients radiation dose during cardiac catheterization procedures in Al-shab teaching hospital in Khartoum state, Sudan. Staff doses measured in (61) procedures (43) for diagnostic (CA) and (18) for therapeutic percutaneous Coronary Interventional (PCI) procedure using thermo-luminesces Dosimeters (TLDs) (LiF, Mg, Cu, P) at three anatomic locations (waist, chest and hand) for main operator and in the chest to assistant operator. While for patient; the dose measured using dose area product (DAP) meter. The radiation dose for the main operator's waist, chest and hand were 0.0608, 0.1127, 0.2125mGy respectively and for the assistant operator's chest was 0.0134mGy depending on TLD method indicating an increment by 28.8% relative to MPD. The patient dose as DAP measured as in mean 905.479± 6.7mGy. The dose measured in this study was lower than the previous reported studies in literature. This almost due to technical parameters reduction so it reduce the scattering radiation in all examinations which considered one of the major causes of received doses.
