background: radioactive iodine is widely used for the treatment of various thyroid disorders. safety issues are often a source of worry and anxiety for the patients, their families and comforters. the patients are advised to restrict their social and work related activities. the work presented in this study describes the results of a structured survey conducted on patients visiting our hospital...

abstract  introduction: recently uses of medium and high energy x-rays has been increased in iran and radiotherapy centers along with a variety of accelerators have been installed in some provinces. in the other hand there is no sufficient skill in designing and making radiotherapy treatment rooms. this study was conducted to evaluate the efficacy of different mixtures of barite concrete for sh...

objective: reporting some biological side effects with special attention to reproductive points which were seen after different experiments in laboratories of the plasma physics & nuclear fusion in atomic energy organization of iran. materials and methods: dosimeter analysis and interpretation of biological side effects of research studies in nuclear fusion laboratories. results: in the last 3 ...

Skin cancer caused by ultraviolet (UV) radiation has risen to prominence in the occupational disease sector. When establishing the work-related preconditions for recognition of occupational diseases, it is important to investigate of the sick person’s exposure to UV radiation. Employees engaged in welding work in particular may be exposed to a high level of UV radiation. Although it is possible...

Background Probability of causation (PC) is a reasonable way to estimate causal relationships in radiation-related cancer. This study reviewed the international trend, usage, and critiques of the PC method. Because it has been used in Korea, it is important to check the present status and estimation of PC in radiation-related cancers in Korea. Methods Research articles and official reports re...

today, nuclear medicine has rapidly been developed so that in some cases, plays a unique role in diagnosis but unfortunalty in spite of diagnostic and therapeutic advantages, the term “nuclear” can induce worries in patients and society. in this article, base on new documents, we intend to show that this worries has no scientific basis. to produce a realistic view, regarding to radiation protec...

PURPOSE OF REVIEW To review the recent literature on the implications of occupational radiation exposure in anesthesia practice. RECENT FINDINGS Wide variation and lack of reduction in operator doses of medical radiation strongly suggests that more attention must be paid to the factors influencing radiation dose exposure. The eye is likely the most sensitive organ for radiation injury. Radiat...

A Joint Working Group was established in April 1995 by the President of the Atomic Energy Control Board (AECB) and the Assistant Deputy Minister of the Health Protection Branch of Health Canada to examine the similarities, disparities and inconsistencies between the levels of risk considered acceptable for regulating ionizing radiation and those considered acceptable for regulating chemical and...

Introduction: The aim of this study was to design a standard questionnaire facilitating the evaluation of the knowledge and attitude of medical students regarding radiation protection. Methods: At first, a 30-item questionnaire was prepared. The scale construction procedure was performed using content validity assessment. Considering objectives, some items were...

The information for the present discussion on the uncertainties associated with estimation of radiation risks and probability of disease causation was assembled for the recently published NCRP Report No. 171 on this topic. This memorandum provides a timely overview of the topic, given that quantitative uncertainty analysis is the state of the art in health risk assessment and given its potentia...
