This research aimed to assess the levels of natural radionuclides in soil Riruwai mining area and evaluate radiological hazards associated with them. A total sixty samples were collected from four sampling sites during dry wet seasons. The concentrations uranium-238 (238U), thorium-232 (232Th), potassium-40 (40K) measured using an HPGe gamma-ray spectrometer, used estimate internal external gam...

cesium content and some other more radiologically important mineral elements were measuredby nuclear and non-nuclear analytical methods in iranian daily diets.this study was extended to a few moresimilar functioning elements such as sr, rb, i, k, mg and ca as well. though the 137cs and otherradionuclieds were not measured in these diets under planned regular investigation in this work, but inco...

a study on natural radioactivity in virgin and agricultural soil samples collected from sungai petani was conducted using high-purity germanium. the mean activity concentrations of 226ra, 232th, and 40k in virgin soils were 51.06±5.83, 78.44±6.42, and 125.66±7.26 bq kg−1, respectively, while those in agricultural soils were 80.63±5.78, 116.87±7.87, and 200.66±18.24 bq kg−1, respectively. the co...

Personal protective equipment (PPE) refers to clothing and equipment designed to protect individuals from chemical, biological, radiological, nuclear, and explosive hazards. The materials used to provide this protection may exacerbate thermal strain by limiting heat and water vapor transfer. Any new PPE must therefore be evaluated to ensure that it poses no greater thermal strain than the curre...

background: in response to the need for diagnosis and treatment, medical radiation has been increasingly used worldwide. this study investigated the medical utilization of radiation-related diseases among radiological technologists (rts) and factors that influence such diseases. materials and methods: data were collected from the taiwan national health insurance research database. a panel study...

There are three parts to this talk – related in rather tangential ways. First, I will give a recap of an argument developed in a couple of earlier talks – at IIiX in 2008 and at the SIGIR evaluation workshop in 2009. The gist of the argument is about thinking about IR as a science, and the consequences Appears in the Proceedings of The 2nd International Workshop on Contextual Information Access...

Resumo. Com a rápida evolução dos sistemas computacionais, simulações numéricas baseadas em modelagem computacional têm alcançado soluções cada vez mais realistas. Ainda assim, o processo de simulação é complexo, exigindo grande capacidade computacional e produzindo muitos arquivos auxiliares com os resultados das simulações. Uma grande quantidade de arquivos, como os produzidos durante o proce...
