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...

the currently reactor wreckage in fukushima raised the following important questions: is our knowledge of the possible dangers of ionizing radiation sufficient to warrant special action? what is the role of the medical community in technical radiation accidents from windscale to fukushima? what is the role of the medical community in terrorist radiation attacks? are we prepared for those challe...

naturally occurring radionuclide of terrestrial origin (also called primordial radionuclide) are present in various degrees in all media in the environment, including the human body itself. their concentrations in environment decrease continually by decaying. the main objective of this study is to evaluate the radioactivity levels and health risks due to terrestrial radionuclide in soil of yal...

background: to evaluate the risk involved, there is need to know the quantum of personnel exposures in whole service. dose reports from an oncology centre over 7 block periods, 5 years each from 1979 till 2013 are analyzed. materials and methods: personnel monitoring (pm) reports till 1990s with film badges and later thermoluminescent (tl) badges (caso4.dy) were evaluated. 35 years total servic...

background: the sporadic cases of radiation-activated multiple sclerosis (ms) has been previously described, with a few studies focused on the relationship between radiation and the risk of ms. the aim of our study was to evaluate the association between history of x-ray radiation and ms.   methods : this case-control study was conducted on 150 individuals including 65 ms patients and 85 age- a...

background: coronary angiography is a commonly performed diagnostic procedure with life saving benefits for the patient. however, this procedure involves relatively high radiation dose. the purpose of this study was to determine the average effective dose of patients undergoing coronary angiography and to estimate the associated radiation risk in terms of fatal malignancy. materials and methods...

Background: This study aimed to investigate dose area product (DAP), effective dose, and radiation risk in newborn infants hospitalized in neonatal intensive care units in Isfahan and Kashan. Materials and Methods: During a period of six months, DAP for chest X-ray examinations for newborn infants hospitalized in NICUs of five special hospitals including Beheshti (in Kashan), Al-Zahra, Imam Hos...
