Determination of 226Ra and 228Ra concentrations in foodstuffs consumed by inhabitants of Tehran city of Iran
ABSTRACTBackground : The presence of primordial radionuclide in human habitats has always been a source of prolonged exposure. Measurement of naturally occurring radionuclides in the environment can be used as baseline to evaluate the impact of non-nuclear activities and also routine releases from nuclear installations. Materials and methods: A total of 56 samples from 18 different foodstuf...
متن کامل210Pb-226Ra disequilibria in young gas-laden magmas
We present new 238U-230Th-226Ra-210Pb and supporting data for young lavas from southwest Pacific island arcs, Eyjafjallajökull, Iceland, and Terceira, Azores. The arc lavas have significant 238U and 226Ra excesses, whereas those from the ocean islands have moderate 230Th and 226Ra excesses, reflecting mantle melting in the presence of a water-rich fluid in the former and mantle melting by decom...

متن کامل226Ra, 210Pb, 210Bi and 210Po deposition and removal from surfaces and liquids
Deposition of 226Ra from water on nylon was investigated. Measurements performed for different pH and different radium concentrations in the water gave similar absolute activities deposited on the foil surface. Obtained results were used to estimate the amount of 226Ra plated-out on the nylon scintillator vessel in the solar neutrino experiment BOREXINO during filling of the detector. Another p...
متن کاملAnalytical study of 226Ra activity concentration in market consuming foodstuffs of Ramsar, Iran
BACKGROUND Ramsar, a city of Iran located on the coast of the Caspian Sea, has been considered to be enormously important due to its high natural radioactivity levels. People living in High Level Natural Radiation Areas (HLNRAs) have been exposed by several sources, one of which could be foodstuff. However, many studies have been carried out to measure the environmental radioactivity in Ramsar,...
