“…However, our work is at variance with more recent work by G.M. Ardran et al ( 12) regarding principal operator exposures during cardiac catheterization (9,101. In reviewing Ardran's work, several points are in question.…”

With the increased utilization of portable image intensifiers for pacemaker insertions, an investigation of the radiation hazards to operative personnel was undertaken. The personnel were tested first utilizing a Rando phantom and later during actual pacemaker insertions. Studies of medical personnel show the critical organs to be the thyroid (approximately 15mR per procedure) and the lens of the eye (approximately 13mR per procedure). While the MPD/week was not exceeded, the radiation dosage was substantial and could increase under operating conditions other than those measured. Recommendations to insure safer operation of this equipment are presented.

“…There are other technical factors which can alter a direct comparison between our study and Ardran's work. Our fluoroscopic field size, for instance, was 176 cm2 while Ardran's study listed 117 cm' for fluoroscopy and 240 cmS for cineradiography (12). Image intensifier input phosphor size, focal spot to patient distance.…”

“…In cardioangiography the absorbed doses to the fingers of the radiologist were higher than those to the wrist measured by ARDRAN & FURSDON (1973) . Nevertheless, they remained well below the permissible doses (75 rad) recommended by I eRP ( 1966), even if all angiographic examinations (in our department some 1 500 per year) would be performed by the same radiologist.…”

“…The main beam carries the diagnostic information, and being of high intensity, constitutes the chief radiation hazard to the patient. Scatter consists of radiation of lower energy deviated in all directions, including backwards from the main beam measured by various studies [2][3][4][5][6] and radiation hazards to the cardiologists were reported in detail by a subcommittee of the British Cardiac Society in 1993. 7) With regard to the hazard of radiation doses, current assessment by the International Commission on Radiological Protection (ICRP) indicates at low doses and at low dose rates a fatal cancer rate of 4% for a working population age 24-62 years.…”

Evaluation of DNA Damage in Lymphocytes of Cardiologists Exposed to Radiation During Cardiac Catheterization by the COMET ASSAY

SUMMARYThis study was designed to evaluate the possible in vivo induction of DNA damage by exposure to radiation in cardiologists. The alkaline comet assay (single cell gel electrophoresis, SCGE), which appears to be a promising tool with which to estimate DNA damage at the single cell level, has been used. The assay was carried out on 30 cardiologists currently employed in a busy cardiac service and 30 healthy unexposed controls. Venous blood samples were obtained from the exposed and control subjects and SCGE was examined in 100 cells graded as undamaged, intermediate, and tailed nuclei. The number of undamaged nuclei was almost the same in control and exposed subjects. The extent of DNA migration (SCGE assay) did not distinguish between the samples in either the nonsmoker exposed or nonsmoker control subjects, which leads one to wonder whether a difference in DNA damage really exists. Previous studies reported increased DNA damage in blood lymphocytes of smokers. In our study, the percentage of damaged cells increased either with the frequency of smoking or exposure to radiation. A statistically significant difference was observed both in smokers and exposed subjects.In conclusion, the elevated grade of DNA damage in cardiologists exposed to radiation indicates a possible genotoxic hazard, therefore, careful measures and full cooperation between cardiologists and radiologists should be undertaken to reduce the exposure to radiation.
