Radon is a natural radioactive gas produced by the decay of uranium and thorium, which are present in all rocks and soils in small quantities. There are several isotopes of radon, the most important of which are 222Rn (produced from 238U) and 220Rn (produced from thorium). 220Rn is also known as thoron because of its parent radionuclide. In the United Kingdom, it has been shown that 220Rn deliv...
A survey was carried out to determine activity concentration levels and associated dose rates from the naturally occurring radionuclides 232Th, 238U and 40K, in the various geological formations of Cyprus, by means of high-resolution gamma ray spectrometry. A total of 115 representative soil samples were collected from all over the bedrock surface of the island, based on the different lithologi...
Background: Natural background radiation of a particular region is one of the distinctive factors defining the status of environment. Eloor Island is an industrial area in Ernakulum District of the state of Kerala, India. The indoor and outdoor gamma level measurements have been carried out for the region for evaluating the annual effective dose to the population residing in this area. Mate...
This article presents the results of studies content natural (228Ra, 226Ra, 232Th, 40K, 210Po, 210Pb, 238U) and technogenic (137Cs, 90Sr) radionuclides in drinking water from centralized (wells) decentralized supply sources observation area Belarusian NPP, performed 2016 to 2020 within framework radiation hygienic monitoring at stage construction NPP.
The study investigates commercially available negative ion clothing, and evaluations are made using gamma-ray spectroscopy Geant4 Monte Carlo simulations. Observed to contain naturally occurring radioactive material (NORM), of the radiological risk arising from use these as items everyday wear, undergarments in particular. Organ doses were simulated MIRD5 mathematical female phantom, with incor...
Measurements of natural radionuclide (NORMs) and artificial in airborne particulates obtained from around prospective site area Nuclear Power Plant (NPP), West Kalimantan, Bengkayang have been carried out. In the NPP development plan, data potential sites should be measured to determine baseline environmental data. The objective research was obtain ambient air quality radiological aspects gamma...
