Human activities such as oil and gas production can enhance the natural level of naturally occurring radioactive materials (NORM) in by-product and waste streams. Iran has been among the top five oil producing countries since 2005. This high production rate emphasizes the importance of NORM management to ensure the safety of humans and wildlife. Petroleum storage and transport facilities are lo...

This paper summarizes technological advances in diagnostic radiography, fluoroscopy and computed tomography, mainly the developments in digital detectors and helical CT scanners with multiple-row detectors. It reviews dosimetric concepts and presents the most up-to-date information on the global patterns of use of radiological modalities as well as the trends in diagnostic medical exposure dose...

In 2010, the US National Council on Radiation Protection and Measurements (NCRP) established a scientific committee (SC5-1) to prepare a comprehensive report on the framework and approach for optimising decision making in late-phase recovery from nuclear or radiological incidents that lead to wide-area contamination. The NCRP report builds on recommendations from the International Commission on...

We predicted that adopting a performance-approach vs. performance-avoidance goal would lead to physiological responses characteristic of psychological states of challenge vs. threat appraisals, respectively. Furthermore, we predicted that these states would mediate the effects of goals on performance. Twenty-seven undergraduate females performed a task described as identifying either exceptiona...

abstract background: monitoring internal exposure of individuals handling significant amounts of iodine-125 (i-125) for iodination is of great importance. these individuals are potentially exposed to external contamination, and internal contamination through inhalation, ingestion and intact skin absorption, to i-125. considering radiological toxicity of this radionuclide its monitoring in the w...

This study evaluates pre- and post-clinical training radiation protection awareness knowledge among medical imaging students. A cross-sectional of 120 students from Malaysian public universities was undertaken. The survey is based on the developed Healthcare Professional Knowledge Radiation Protection (HPKRP) scale. There a significant difference between pre in their but no other radiological k...

Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this basic anatomical and physiological data for use in radiological protection the skeleton...

Interestingly, principles for intervention for protection of the public in a radiological emergency that you really wait for now is coming. It's significant to wait for the representative and beneficial books to read. Every book that is provided in better way and utterance will be expected by many peoples. Even you are a good reader or not, feeling to read this book will always appear when you ...
