In Radiation processing of products by high energy electrons, scattered electrons reduce at the edges of the product and the absorbed dose is low at this regions. Dose reduction in edges, affects some system parameters such as dose uniformity ratio, Energy utilization efficiency and mass throughput.In this paper,the 3-D dose distribution in the sample product was determined by MCNP computer cod...
OBJECTIVES This study sought to determine the efficacy of low rate fluoroscopy at 7.5 frames/s (FPS) versus conventional 15 FPS for reduction of operator and patient radiation dose during diagnostic coronary angiography (DCA) and percutaneous coronary intervention (PCI) via the transradial approach (TRA). BACKGROUND TRA for cardiac catheterization is potentially associated with increased radi...
Nowadays, the radiological risk from simple X-ray procedures is well known. The purpose of this work has been to estimate the population risk from digital angiographic and interventional procedures and to compare it with the one from simple procedures in the same population. The population risk has been estimated according to the following quantities: genetically significant dose, somatic signi...
