The radioactivity in tobacco leaves collected from 15 different regions of Greece and before cigarette production was studied in order to find out any association between the root uptake of radionuclides from soil ground by the tobacco plants and the effective dose induced to smokers from cigarette tobacco due to the naturally occurring primordial radionuclides , such as 226Ra and 210Pb of the ...

This study aimed at evaluating natural radioactivity and radiation hazards of soils around a petroleum product marketing company due to anthropogenic influences using gamma ray spectrometry. Top (5 cm deep) were collected from diverse locations inside the premises Company standard analytical technique, while control samples acquired approximately 200 m area. Mean activity concentrations radionu...

This paper presents data on the content of toxic elements (Mn, Ni, Zn, Cu, Pb, As, Cr, Cd and Co), technogenic (137Cs, 134Cs) natural radionuclides 238U 232Th series (234Th, 226Ra, 210Pb, 232Th) 40K in sediments collected from ten sampling stations along northern Bulgarian Black Sea coast for a period more than twenty years. Measurements were made by Gamma Spectrometry Inductively Coupled Plasm...

This study was carried out to determine the presence of main radionuclides from natural and artificial radioactivity in soil Kosovo, using gamma-ray spectroscopy. The mean activity concentration for Ra-226, Th-232, K-40, Cs-137 22.32 ± 1.41, 22.14 1.31, 358.16 8.85, 12.94 0.44 Bq/kg, respectively. Radium equivalent ranged 47 100 Bq/kg. calculated values gamma index (Iγ), external hazard (Hex), ...

Flue gas desulfurization (FGD) waste is an industrial by-product generated during the flue process in coal-fired power plants. This contain trace quantities of naturally occurring radionuclides and elements such as As, Ba, Co, Cr, Zn. The characteristics FGD are important for its reuse mainly depend on process. In this work, two types materials collected from three plants using semi-dry wet pro...
