Sažetak
The aim of this work was the determination of staff exposure during coronary diagnostic procedure and the investigation of the effect of some factors (working method, fluoroscopy time, physical characteristics of cardiologist) on the doses to personnel. The measured doses in this work were compared to the doses measured by the National Dosimetry Service. The doses were measured with LiF:Mg, Cu, P thermoluminescence and phosphate glass radiophotoluminescence dosimetry systems (GD-352M) under and over the apron on the chest, on the left eye (eyebrow), left shoulder out of the apron, and left wrist of 3 cardiology doctors. Each doctor carried out 5 diagnostic coronary angiography procedures. The annual effective doses Eeff, calculated from the measured values as well as the equivalent doses to the eyes, were in all cases below the required dose limit (20 mSv/y ear). Significant differences of the effective doses were found among the three doctors in this study (15.5 mSv, 10.4 mSv, 8.7 mSv), as well as in the earlier results of the National Dosimetry Service (9.2 mSv, 4.6 mSv, 1.3 mSv). It was found that a single dosimeter under the apron performed by the National Service underestimates the Eeff as compared to the double dosimetry carried out in this study. The doses depend on many factors in coronary angiography, such as fluoroscopy time, complexity and number of examinations, experience of the doctor, feature of the doctor (height) and patient himself.
