Introduction:   Nowadays we are witnessing an exponential application of interventional radiology techniques in various communities as well as Iran. Radiological technique is regarded as  the  2nd  contributing  factor in  increasing  the  amount  of  public  doses  in various societies. So that related radiation protection organization has recommended measuring patient d...

Introduction The purpose of this study was to estimate organ and effective doses in patients undergoing some common X-ray examinations in Sabzevar, Iran. The effective dose is one of the best parameters for describing the amount of radiation dose received by a patient undergoing any diagnostic X-ray examination. The public dose from X-ray examinations depends on various factors, and its contrib...

Introduction: In 2000, the UNSCEAR reported that CT constitutes 5% of all the medical x-ray  examinations and it contributes 34% of the resultant collective dose worldwide. Children are more  sensitive to the ionizing radiations than adults. So, routine quality control tests are expected to be  carried out periodically on the CT scanners. The aim of this research was to estimate the effective  ...

Introduction: Assessment of occupational exposure to external radiation and the analysis of associated trends are imperative to observe changes that have taken place over time due to regulatory operations or technological advancements. Herein, we describe the occupational radiation exposure to workers employed in Nuclear Medicine (NM), Radiotherapy (RT), and Diagnostic Radiology (DR) department...
