background: the aims of the study are to determine the radioactivity concentrations of 226ra, 238u, 232th and 40k in vegetables of a recently found high background radiation area of south-eastern part of bangladesh and to detect the radiological risks to human from intake of these vegetables. materials and method: 10 plant samples were collected randomly from different locations of the study ar...

Agricultural researchers in many countries investigate radiological risks soil and crops because it concerns human health. In addition, they also study heavy metal pollution plants cultivated for ecological safety. This aims to analyze the activity concentrations of radionuclides metals corn Küçük Menderes Basin (Izmir, Turkey) – which is enriched with phosphatic fertilizers. We collected sampl...

Ra, Ra and Ba distributions as well as Ra/Ra and Ra/Ba ratios were measured in seawater, suspended and sinking particles at the DYFAMED station in the Western Mediterranean Sea at different seasons of year 2003 in order to track the build-up and fate of barite through time. The study of the Raex/ Raex ratios (Raex = Ra activities corrected for the lithogenic Ra) of suspended particles suggests ...

The aim of this study is to analyse the role natural radionuclides 226Ra, 228Ra, 40K and unsupported 210Pb (210Pbex), as erosion accumulation process tracers. For purpose, a complex system, including both characteristic dynamics closed beach those associated with open wave action, was studied. A 3-year monthly variation 210Pbex carried out at Las Canteras beach, on Island Gran Canaria (Spain), ...

Understanding the speciation and fate of radium during operational discharge from offshore oil gas industry into marine environment is important in assessing its long term environmental impact. In current work, 226Ra concentrations sediments contaminated by produced water a site UK were analysed using gamma spectroscopy. Radium was present field samples (0.1–0.3 Bq g−1) within International Ato...

Activity concentrations of radionuclides (238U, 226Ra, 232Th, and 40K) in the sediments eight sampling stations heavy metal (Cr, Co, Ni, Cu, Zn, As, Cd, Pb) two long cores from Nansha Sea area were obtained by high-purity germanium spectroscopy inductively coupled plasma atomic emission spectrometry. In a correlation analysis between metals, 232Th was positively correlated with As Pb. 238U demo...

background: knowledge of radioactivity levels in human diet is of particular concern for the estimation of possible radiological hazards to human health. however, very few surveys of radioactivity in food have been conducted in iran therefore the baseline values of the natural radionuclides concentration (40k, 226ra and 232th), and man made radionuclide, 137cs, were determined in twenty six sam...
