background: the use of the ionizing radiation in the medical practice has evolved since its beginnings. their benefit for the patient is considerable in term of comfort, diagnostic and therapeutic effectiveness. it is estimated that 30% to 50% of critical decisions in medical approaches is based on x-ray examination. using the x-ray as a diagnostic means by clinicians requires appropriate and a...
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...
this paper presents the current activities on radiation protection in iran. according to the atomic energy organization law of iran the radiological safety is ascribed to the atomic energy organization of iran (a e o i) and the radiation protection department (r p d) is the responsible organ within aeoi. r p d since it's establishment in 1975, with the aim to ensure the protection of man and hi...
conclusions comprehensive protection programs with on-the-job training courses for staff members are strongly recommended, as well as, the provision of radiological shields and gonad shielding protocols in radiology departments to reduce the patient’s radiation dose during radiological examinations. materials and methods a retrospective, observational cross-sectional study on the application of...
Statement of Problem: A few decades have past from using radiographic technology as an accurate paraclinical method and always protective measurements is applicated against ionizing radiation. As dental radiography is a routine procedure in dentistry the importance of protective strategies is clear.Propose: The aim of this descriptive study is to evaluate the protection principles in centers wh...
background: the aim of the study was to estimate the radiation dose during emergency exposure to patients treated with iodine-131 during the isolation period. materials and methods: the dose rate from a sample of 192 patients administrated by three different radioactivity of 131i (3.7, 5.55 and 7.4 gbq) was measured, at 1 meter after 1, 24 and 48 hours post dose administration, at three differ...
