Estimation of Exposure Level of Radioactive Waste in Elnileen Medical Diagnostic Center

Abstract

Many studies have shown that the vulnerability of nuclear medicine technologists to radiation is evident from the radioactive waste. We in this study have drawn upon the existing activities in the nuclear medicine department at the centre of Elnilain for medical diagnosis, where continued study for more than 8 days, and the purpose of this study was to estimate the level of the dose to technologist , nurses and other persons who were present in the hot lab from the Department of Nuclear Medicine during the elution process of the generator of TC-99m, and then compare the results of the dose that subjected them to the standards of the International Radiation Protection (ICRP). In this study, using of survey meter type (Victoreen 451) to measure doses of radiation, and of which we found that the cumulative dose of the hands of technologist approximately 9.4 mSv per year and this dose is less than the limits of dose permitted 500 mSv per year, also found that the dose to technologist 3.6 mSv per year and this is also less than the dose limit with 20 mSv per year, and the dose to the nurse was 1 mSv per year, less than allowed by 20 mSv, the patient also we found that it is exposed to dose of 0.8 mSv and this value concern near to the 8 ‫‪allowed 1 mSv the non-working people(public). And the co- patient exposed‬‬ ‫‪to a dose of 0.3 mSv, and this value is less than the allowable limit 1 mSv for‬‬ ‫‪.public‬‬
