The main objective of the present study was to assess natural radioactivity level from soils an abandoned potash mine and its surroundings at Holle locality in Hinda district, Republic Congo. Samples were analyzed using HPGe gamma spectrometer. Activity concentration values obtained varied 21.01 ± 6.47 117.3 2.69 Bq/kg with a mean value 46.15 4.69 40 K; that 238 U 17.36 10.74 40.04 8.58 25.14 1...

Radioactivity is known to induce tumors, chromosome lesions, and minisatellite length mutations, but its effects on the DNA sequence have not previously been studied. A coastal peninsula in Kerala (India) contains the world's highest level of natural radioactivity in a densely populated area, offering an opportunity to characterize radiation-associated DNA mutations. We sampled 248 pedigrees (9...

Background: Vegeta on (food stuff) is grown in soil that contains many radioac ve elements such as 238 U (uranium), 232 Th (thorium) and 40 K (potassium), which may get deposited either due to radioac ve fallout or/and by absorp on from the soil and can pose serious health hazards. Materials and Methods: Natural radioac vity, radiological hazards and annual effec ve dose assessment was carried ...

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 artificial and natural radionuclides are found in diverse environmental compartments, such as water, soil, rocks, vegetables, animals, and human body tissues. as such, humans and environments are at constant exposure of these radiation types. in this research investigated specific activities of radionuclide and dose assessment of some species of mushrooms. materials and methods in ...

Determination of activity concentrations in twenty five (25) soil samples collected from various points in bauxite ore deposit in Menoua Division in Western of Cameroon was done using gamma spectrometry based Broad Energy Germanium (BEGe6530) detector. The average terrestrial radionuclides of (40)K, (226)Ra, (232)Th, (235)U and (238)U were measured as 671 ± 272, 125 ± 58, 157 ± 67, 6 ± 3 and 99...
