Groundwater is an important freshwater resource, which can be affected by geogenic radionuclide contamination. To make decisions regarding the use and management of groundwater, understanding controls mobility critical. In southern foreland a granitic outcrop in Hungary, high gross alpha activity concentration was measured drinking water wells, related probably to presence uranium. It has been ...

Exploration of a landlocked cenote on Lifou (Loyalty Islands) revealed 37 shells of the cephalopod Nautilus macromphalus Sowerby, 1849, in saltwater on the cenote floor, approximately 40 m below the water surface. The occurrence of these shells is unusual because N. macromphalus is restricted to the open marine waters surrounding the island. All of the shells are mature, and nearly all of them ...

There is considerable interest in the chemical composition of smokeless tobacco products (STPs), owing to health concerns associated with their use. Previous studies have documented levels of 210Po, 210Pb and uranium in STP samples. Here, the levels of 13 α-particle and 15 β-radiation emitting radionuclides have been measured in a broad and representative range of contemporary STPs commercially...

background: two of the important radionuclides which are entered to environment and human diet are radium-226 (226ra) and cesium-137 (137cs). it is clear that the methods for preparation of foods such as peeling, washing, cooking or frying can affect the dose which is received by human due the to consumption of foodstuffs. an experiment has been performed at the environmental monitoring section...

Many food products are recommended to give health benefits. Thus algae superfoods consumption is growing worldwide, although quite a few studies have examined the quantities of radionuclides they contain and their potential effects on human health. The study presents radioactive 40K, 137Cs, 226Ra, 228Ra, 234Th in supplements available worldwide for consumption. Samples been quantified by gamma-...

Background: In this study, the health risk associated with three types of drinking waters (fissure, underground treated and surrounding waters) from two mines in South Africa were assessed. Materials and Methods: The measurement of the radionuclides concentration was carried out by liquid scintillation counter and alpha spectrometer. The estimated radiological risk pose to the people consuming ...
