Background: Radiology tests are used to diagnose a variety of diseases. Performing such examinations has potential risks for patients and radiographers working in radiology departments. These risks can be minimized by compliance with safety practices. The aim of this study was to assess the knowledge, attitude, and practice of radiographers working in the radiology departments of Yazd about the...

To protect themselves, their patients and their coworkers, radiologic technologists should regularly refresh and reinforce their understanding of key radiation biology and protection principles. This article reviews the concepts of radiation physics, human biology and radiation protection strategies, with emphasis on how historical events and developing research affect radiation protection unde...

Background: Although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. One of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. The aim of this study was to determine the physicians' knowledge in radiological examinations. Materials and Methods:...

Reflecting the change in funding strategies for European research projects, and the goal to jointly improve medical radiation protection through sustainable research efforts, five medical societies involved in the application of ionising radiation (European Association of Nuclear Medicine, EANM; European Federation of Organizations for Medical Physics. EFOMP; European Federation of Radiographer...

Introduction: The ionizing radiation is increasingly applied in various fields for industrial and medical purposes due to its benefits. The aim of this study was to measure the radiation levels in six radiology departments of two educational hospitals in Ahvaz, Iran. Materials and Methods: The radiation levels were measured at six locations of six radiology departments, including behind the pat...

Introduction: Exposure to ionizing radiation can be through direct hit or water radiolysis lead to oxidation in biological systems. In this study, the protective effect of Myrtus Communis aqueous extract on structural changes and oxidative stress in red blood cells and plasma proteins was examined after receipt of ionizing radiation. Materials and Methods: wis...
