High-level natural radioactivity, geochemical, geological, and radiological hazard assessment of the poorly investigated Wadi Gebeiy Dokhan volcanics rocks are discussed. located in Southwestern Sinai, Egypt, covering an area ~1.3 km2. represented by porphyritic dacite. Geochemically, they have medium-k characters originate from calc-alkaline magma within a arc environment. Along fault plane st...

background: turkey, especially the northern part of it, was one of the countries which were contaminated by the chernobyl accident.  rize is a city located in the northeastern district of turkey which was heavily influenced by the chernobyl nuclear accident. materials and methods: in this study, the activity concentrations of natural (226ra, 232th, 40k) and artificial (137cs) were measurements ...

The present study was carried out on commercial types of Aswan granite used as building and decorative materials. Nearly 29 granitic rocks samples from 11 classes (black Aswan, red dark Rosa, light yellow Verdi, grey Shirka, Gandolla, Forsan, Nefertiti, Royal, white Halayeb) were collected three stations near city for petrographical description assessment natural radioactivity. granites conduct...

Contaminated mass fatalities following the release of chemical, biological, or radiological agents pose a potential major health hazard. A United Kingdom government investigation has identified a number of areas of risk. This paper presents an outline of the findings of the study and describes specific pathways for the management of contaminated and non-contaminated fatalities. Factors determin...

INTRODUCTION The radioactive isotopes of ruthenium with mass numbers 103 and 106 are common fission products and may represent a radiological hazard for the population in case of their release into the environment and transfer to the food chain. Ru, having a half-life of 39.26 d, decays by β emission onto Rh. Ru (T1/2=374 d) is a pure β emitter, and its daughter nuclide, Rh, is radioactive as w...

human infection with avian influenza a h7n9 virus has emerged in china with high morbidity rates. patients usually present with severe and rapidly progressive pneumonia. therefore, radiological findings are important to diagnose and evaluate disease severity. the clinical characteristics of three new cases of h7n9 virus infection were analyzed, especially the radiological findings, and previous...

The ability to predict hazards in possible situations in a general X-ray examination room created for Kiken-Yochi training (KYT) is quantified by use of free-response receiver-operating characteristics (FROC) analysis for determining whether the total number of years of clinical experience, involvement in general X-ray examinations, occupation, and training each have an impact on the hazard pre...
