خلاصه يا چکيده : ‭ray unite was Axiom Artis Siemens for both hospitals. Both unites were equipped with an integrated Dose Area Product meter system. Procedures were divided into two groups: diagnostic procedures (angiography, angiography with measurement of left or right ventricle and pulmonary artery pressure) and therapeutic procedures (angioplasty with or without dilatation or stent, angiography with angioplasty).Dose Area Product values, fluoroscopy time and cumulative dose at international reference point also were registered for each procedure. Results The mean value of MSD and DAP were respectively for diagnostic procedures 68.51mGy, 20.96Gycm2 and for therapeutic procedures 344.18mGy, 70.94Gycm2. The highest dose received by patients was observed related to Left Anterior Oblique angles. A good correlation found between MSD and DAP(R=0.88); but correlation between MSD and CDIRP was stronger (R=0.90). Conclusion For none of the cases MSD exceeded the 2000mGy dose threshold for deterministic effects. The highest MSD for diagnostic procedures was 229.40mGy and for therapeutic procedures was 820.50mGy. The results showed that CDIRP can be a fairly good estimator of MSD. Keywords Maximum Skin Dose (MSD), Interventional Cardiology, Thermo Luminescence Dosimeter. -Background The increasing use of interventional radiology in diagnosis and treatment of heart diseases has led to special attention to improving the quality of radiation protection of patients and cardiologists in these procedures which radiation dose is relatively high. Therefore there is an abundant emphasis on measurement of radiation dose received by patients and cardiologists. Methods Maximum skin dose of 90 patients in two hospitals in Mashhad was measured using a grid of 30 TLD. The X‬
