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 ...

Naturally occurring radioactive materials (NORMS) and fallout 137Cs were estimated in surface soils from the highly mineralized Singhbhum region of Eastern India. The activity concentrations varied from 50.67-109.14 Bq/kg (238U), 48.12142.55 Bq/kg (226Ra), 28.73-89.78 Bq/kg (232Th), 494.84-1121.36 Bq/kg (40K) and 1.8-7.48 Bq/kg (137Cs). Correlation between radionuclides was studied. 232Th/238U ...

Background: The activity concentrations of natural radionuclides in soil around a coal-fired thermal power plant of northwest China were investigated for assessing the radioactivity level. Materials and Methods: Soil samples were collected around the coal-fired thermal power plant and their radioactivity levels were determined using gamma ray spectrometry. Radiation hazards were assessed by rad...

This paper aims to estimate a potential radiological risk from different kinds of coals used for domestic heating in Serbia, by measuring the activity concentration radionuclides and radon exhalation rate. The obtained mass rate ranges (5.3 ? 3.1) mBqkg?1s?1 (70.3 9.4) mBqkg ?1s?1 was highest lignite type coal. It is estimated that coal stored basement could contribute up 50 Bqm?3 indoor at gro...

Radiometric investigation in a rainforest of the Golfo Dulce region of southern Costa Rica has shown the presence of the anthropogenic radionuclides caesium-137, strontium-90 and the plutonium isotopes 238, 239 and 240 along with the naturally occurring radionuclides 7Be, 40K, 238U and 232Th, and respective progenies. 137Cs, 90Sr and Pu can be attributed to global fallout; no other sources coul...

background: activity concentrations of 40k, 226ra and 228ra were measured in some sachet drinking water samples produced in nigeria. materials and methods: the measurement was done by using high-purity germanium (hpge) detector (canberra industries inc.). the measured activity concentrations for 226ra (u-series) and 228ra (thseries) were used with their ingested dose conversion factors to estim...

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...

The potential re-use of red mud in the building and construction industry has been subject research many scientists. presented is a contribution to solution this environmental issue through synthesis materials based on mud. A promising way recycling these secondary raw alkali-activated binders or alkali activated materials. Alkali-activated inorganic are new class obtained by activation precurs...

Uranium tailings ponds have a potential impact on the soil ecological environment and human health. In this study, measurement spatial distribution characteristics of physicochemical properties (pH, EC, TN, TOC, TP) heavy metals/metalloids (Cd, Pb, Zn, Cr, As) in two different profiles (0–5 cm, 5–15 cm) were completed visualized decommissioned uranium pond Northwest China. The results showed th...

Wheat is one of the world’s most commonly consumed cereal grains. It originates from a type grass (Triticum) that grown in countless varieties worldwide. Bread wheat or common primary species. Several other closely related species include durum, spelt, emmer, einkorn, and Khorasan wheat. In addition to being major source starch energy, also provides substantial amounts number components which a...
