Introduction Quality control (QC) techniques are used in monitoring and maintenance of the components of an x-ray system. QC of radiology devices plays a significant role in reduction of medication dose and optimization of image quality. This study aimed to conduct QC tests on randomly selected radiology devices, installed in diagnostic imaging departments of Iran. Materials and Methods In tota...

Background and Aim: One of the main steps of optimization process in diagnostic imaging is quality control of X-ray devices. If the control quality process and the quality of X-ray equipment are not ensured through a systematic procedure, it can increase the risk of unnecessary exposures among the population. Therefore, this study can reduce the risk of unnecessary exposures in the entire popul...

Control rods are used in nuclear reactors to control fission the core. Different reactor designs must use different rod materials because of neutrons that can be found at various energies. These materials, which made chemical compounds such as B4C, ZrB2, TiB2 or HfB2 absorb neutrons, have absorption properties for In this study, Akkuyu Nuclear Reactors were investigated. It has been taken into ...
