Estimation of the effective dose to the radiologists during fluoroscopy or angiography of abdominal viscera
ABSTRACTBackground: as fluoroscopy or different angiographies are usually evaluated using TL dosimeter. Thismethod is a time-consuming procedure therefore, radiologists are usually worried and unawareof their exact radiation dose received during each fluoroscopy or angiography. In this study, anew trend for quick estimation of effective dose based on measuring air-absorbed dose of thescattered ...
متن کاملEstimation of Annual Effective Dose Due to Ingestion of Natural Radionuclides in Cattle in Tin Mining Area of Jos Plateau, Nigeria
Contamination of land could occur during the extraction and handling of materials containing high levels of naturally occurring radionuclide materials. These radionuclides find their ways into the food chain. The activity concentrations of natural radionuclides 40K, 226Ra, and 232Th in heart, liver, kidney, lungs, spleen and beef of cattle slaughtered and consumed in a tin mining area of Jos Pl...
متن کاملEffective dose conversion coefficients for radionuclides exponentially distributed in the ground
In order to provide fundamental data required for dose evaluation due to environmental exposures, effective dose conversion coefficients, that is, the effective dose rate per unit activity per unit area, were calculated for a number of potentially important radionuclides, assuming an exponential distribution in ground, over a wide range of relaxation depths. The conversion coefficients were cal...

متن کاملDetermination of 40K concentration in milk samples consumed in Tehran-Iran and estimation of its annual effective dose
Background: Since 40K is the most important natural radionuclide in the environment, its concentration was measured for all milk and milk powder samples consumed in Tehran-Iran. Milk was chosen, since because it is a reliable indicator of the general population intake of certain radionuclide, and many environmental programs have been applied for its safety. Materials and Methods: Measu...
