background: health hazards associated with exposure due to the natural radioactivity which is a part of our physical environment are of great concern. in order to assess the risks associated with exposure due to the natural radioactivity in soil and building materials, extensive studies have been carried out all over the world. the most commonly encountered radionuclide’s are 238u, 232th, their...

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. material...

Saline groundwaters with 4.7 to 26%o total dissolved solids were sampled from springs and artesian wells in Mississippian and Ordovician carbonates and sandstones in central Missouri. U-Th isotopic variations provide a means of evaluating processes of water-rock interaction and fluid mixing and estimating the time scales of element transport. Recently developed mass spectrometric techniques are...

background: investigation on the natural radionuclides 238u, 232th, 40k and natural fallout radionuclide 210po in the prominent plants species of western ghats tropical forest near kotagiri have been carried out as a part of baseline background radiation studies in the forest environment. materials and methods: the prominent plants species of the region evodia roxburghiana and eleaocarpus oblan...

Introduction: Investigation on the natural radionuclides 238U, 232Th, 40K and natural fallout radionuclide 210Po in the prominent plants species of Western Ghats tropical forest near Kotagiri have been carried out as a part of baseline background radiation studies in the forest environment. Materials and Methods: The prominent plants species of the region Evodia roxburghiana and Eleaocarpus obl...

Nkamouna-Kongo is a cobalt–nickel deposit located in Lomié, Eastern Cameroon. Mining creates radiation exposure pathways that must be considered risk management scenarios. RESRAD-ONSITE and RESRAD-BIOTA, developed by the US DOE, assess contaminated sites deriving cleanup criteria estimating dose associated with residual radioactive materials using site-specific parameters. This paper evaluated ...

Neutronic analysis on the Molten Salt Reactor FUJI-12 using fissile material 235U in LiF-BeF2-UF4 has been carried out. The problem faced use of thorium-based fuel is that amount 233U small and not available nature. was produced through 232Th breeding at a cost $46 million/kg. That very high price when compared to enrichment, which only $100/kg. MSR used this study generation IV reactor with mi...
