Radiation Dose to Staff during Cardiac Interventional Procedures (Khartoum-Sudan)

The aim of this study was to measure and evaluate the staff radiation dose during cardiac procedures, such as coronary angiography (CA), percutaneous coronary interventions (PCI). Measurements were performed on Staff doses in (65) 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 0.45, 0.47, 0.99mGy respectively and for the assistant operator's chest was 0.324mGy depending on TLD method indicating an increment by 28.8% relative to MPD. The monitoring of radiation workers is not established properly. It is obvious that high patient and staff exposure is due to the lack of experience and protective equipment's. The results presented are comparable with those published by other authors.
