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...

BACKGROUND Radiological examinations are commonly requested for patients to aid clinical diagnosis. However, many doctors do not realise how much radiation dosage their patients are exposed to during radiological investigations. This study aims to assess and compare the knowledge of radiologists and non-radiologists about radiation doses of common radiological investigations. METHODS A prospe...

In a (negative) multicenter randomized trial on management for inoperable critical lower limb ischemia, comparing spinal cord stimulation and best medical treatment, a number of pre-defined factors were analyzed for prognostic value. We included a radiological arterial disease score, modified from the SVS/ISCVS runoff score. The purpose of this analysis was to evaluate clinical factors and comm...

Uranium mining and milling industries are growing rapidly in many countries and this trend is likely to continue with the increasing demand for nuclear fuel. The problems of radiological hazards in this part of the nuclear fuel cycle have received considerable attention in recent years because of the epidenuological evidence of lung cancer among uranium miners, mainly smokers. The hazard is not...

background: although ionizing radiation is widely used to diagnose many diseases, the relevant hazards are known to be as an important limitation of its application. it is believed that the awareness of ionizing radiation dose values is one of the main stages in patient's radiation protection. the purpose of this study has been to investigate the level of physicians' knowledge about r...

The correlation of the medical and environmental data (i.e. the derivation of the dosage-response relationship) in a study such as the National Coal Board's Pneumoconiosis Field Research (P.F.R.) is subject to many complicating factors compared with the more conventional types of biological assay. Several methods have been developed within the Research to overcome these difficulties, and the ne...

This article assesses US government funding in 5 domains critical to strengthening health security: biodefense programs, radiological and nuclear programs, chemical programs, pandemic influenza and emerging infectious disease programs, and multiple-hazard and preparedness programs. This year's article also highlights the emergency funding appropriated in FY2015 to enable the international and d...
