The detonation of a nuclear device in a US city would be catastrophic. Enormous loss of life and injuries would characterize an incident with profound human, political, social, and economic implications. Nevertheless, most responders have not received sufficient training about ionizing radiation, principles of radiation safety, or managing, diagnosing, and treating radiation-related injuries an...

It is evident that there is a nuclear skills shortage within the UK, and logically it can be assumed that the shortfall extends to the radiation protection arena. Plans for nuclear new-build and the decommissioning of existing nuclear sites will require many more people with radiological knowledge and practical competencies. This converts to a nuclear industry requirement in the order of 1000 n...

Radon, an element of natural radiation, is considered one the leading causes lung cancer worldwide. In Bangladesh, radon has been clarified as a foremost source radiation exposure. Potential natural-radiation-induced elevated risks were estimated in Bangladesh previously for population. this survey, very preliminary study country, comparative indoor (222Rn, Rn) and thoron (220Rn, Tn) concentrat...

The magnitude of the risks from low doses of radiation is one of the central questions in radiological protection. It is particularly relevant when discussing the justification and optimization of diagnostic medical exposures. Medical X-rays can undoubtedly confer substantial benefits in the healthcare of patients, but not without exposing them to effective doses ranging from a few microsievert...

iran is one of several countries that has regions of high dose natural ionizing radiation. two wellknown villages in the suburb of ramsar town in the caspian sea strip, taleshmahaleh and chaparsar, have background radiation that is 13 times higher than normal. this radiation is the result of radium 226 and radon gas both of which are highly water soluble. while people living in these regions do...

Over the past few decades there has been some discussion concerning the increase of the natural background radiation originated by coal-fired power plants, due to the uranium and thorium content present in combustion ashes. The radioactive decay products of uranium and thorium, such as radium, radon, polonium, bismuth and lead, are also released in addition to a significant amount of 40K. Since...

All soils and rocks contain naturally occurring radioactive material (NORM). Many ores and raw materials contain relatively high levels of natural radionuclides, and processing such materials can further increase the concentrations of natural radionuclides, sometimes referred to as 'technologically enhanced naturally occurring radioactive material' (TENORM). Examples of NORM minerals include ur...
