The development of new radiation detectors of low cost but with adequate materials is a very important task for countries that have to import ionization chambers such as Brazil. A special double faced ionization chamber was developed for use in conventional diagnostic radiology beams and computed tomography energy ranges. The results show that this new chamber present applicability in conventio...

Introduction: Most of people are exposed to ionizing radiation sources during their lifetime including background, cosmic or man-made beams like radiation used in nuclear medicine and radiology. Due to unavoidable use of ionizing radiation in diagnosis and treatment of diseases, designing and correct implementation of radiation protection principles in order to reducing its har...

Introduction Application of quality control (QC) programs at diagnostic radiology departments is of great significance for optimization of image quality and reduction of patient dose. The main objective of this study was to perform QC tests on stationary radiographic X-ray machines, installed in 14 hospitals of Kerman province, Iran. Materials and Methods In this cross-sectional study, QC tests...
