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:...
background: the number of interventional cardiology procedures performed has increased rapidly over the past years. while these procedures help physicians avoid using highly complicated invasive methods, it usually leads to high levels of exposure to ionizing radiation of both patients and cardiologist. the dose received by the cardiologist during interventional cardiology procedures is determi...
conclusions the state of observed radiation protection principles was relatively in the weak level in the studied radiology departments especially in facilities such as ventilation system, radiography entrance, and darkroom situation. more important reason was usage changing of sections as radiology billet from related organizations. results the mean of radiation protection in the studied radio...
