Diatomite (diatomaceous earth) and clay minerals deposits from the mining basin Kolubara, Serbia, are natural materials with high economic potential in many fields. As received treated materials, diatomite were characterized using X-ray diffraction, mercury intrusion porosimetry, particle size distribution, scanning electron microscopy, Fourier-transform infrared spectroscopy. Activity concentr...

background: radium-226 (226ra) is a product of the 238u radionuclide decay series that significantly incorporated into the human body through water intake. it can also potentially cause a series of health problems including cancers of the digestive system. radium-226 (226ra) is a product of the 238u radionuclide decay series that significantly incorporated into the human body through water inta...

Background: There is a rapid increase worldwide in the consumption of mineral waters which may contain different level of radioactive elements, especially 226Ra, in addition to varying amounts of beneficial salts. Therefore, a comprehensive study was planned and carried out in order to determine concentration of 226Ra natural radionuclide in bottled mineral waters that commercially available in...

To obtain high quality of results in gamma spectrometry, it is necessary to select the best HPGe detector for particular measurements, to calibrate energy and efficiency of gamma detector as accurate as possible. To achieve this aim, the convenient detector model and gamma source can be very useful. The purpose of this study was to evaluate the soil specific activity using two HPGe model (BEGe-...

The activity concentrations of naturally occurring radionuclides in vegetables and peat soil were investigated to determine the transfer factors from obtained farms Klang Selangor. results showed that concentration ranges for 226Ra, 232Th, 40K vegetable 2.72-46.54 Bqkg-1, 9.01-54.84 19.22-477.76 respectively. various samples 0.41-3.41 0.02-3.56 16.22-317.49 soil-to-plant 0.01-0.67, 0.00-0.17, 0...

In the 1999 bombing of the Federal Republic of Yugoslavia, NATO forces used ammunition containing depleted uranium. The cleaning of depleted uranium that followed was performed in southern Serbia by the Vinča Institute of Nuclear Sciences between 2002 and 2007 at the locations of Pljačkovica, Borovac, Bratoselce, and Reljan. This paper presents detailed results of radioactivity monitoring four ...

Introduction Foodstuffs are known to contain natural and artificial radionuclides. Determination of radionuclide concentration is of great significance for the protection of human health. The main objective of the present study was the quantification of radionuclides in tea samples, cultivated in Guilan Province in North of Iran. Materials and Methods The activity concentrations of 226Ra, 232Th...

naturally occurring radionuclide of terrestrial origin (also called primordial radionuclide) are present in various degrees in all media in the environment, including the human body itself. their concentrations in environment decrease continually by decaying. the main objective of this study is to evaluate the radioactivity levels and health risks due to terrestrial radionuclide in soil of yal...
