“…The impact of fertilizer-derived uranium on soils and water is likely to be dependent on several factors, including soil properties (pH, moisture content, mineralogy and texture), fertilizer composition, and water chemical content, therefore, likely to be spatially variable (Zielinski et al, 1997). The aims of this study is to determine the U content in sediment samples collected throughout alkhasa valley for recent sediments of Kirkuk-Iraq using the Inductively coupled plasma -Mass Spectrometry (ICP-MS) in order to evaluate the contamination level of U in the study area.…”

“…Ca, Mg, U, As, Cr, V) and sulphates in addition to cyanide species. Elements such as U, As, Cr, and V tend to form soluble carbonate complexes (Levinson, 1974;Langmuir, 1997;Zielinski et al, 1997;Tutu, 2006 Tutu et al, 2008). They occur on the tailings, next to tailings ponds, along stream banks and on tailings footprints (Fig.…”

“…Zielinski et al (1997), detectaram altas concentrações de urânio dissolvido nasáreas agrícolas irrigadas no sudoeste do Colorado (EUA), concluindo que a presença do radionuclídeo tinha origem nos fertilizantes fosfatados. San et al (1999), investigando a radioatividade em rochas fosfáticas no Sudão, observaram que para dois tipos de rocha (Uro e Kurun), havia teores diferenciados de U e Th, cujos valores médios foram 393,1 Bq Kg −1 e 6,9 Bq Kg −1 , respectivamente.…”

ABSTRACT. Gamma-ray spectrometry, electrical resistivity, and magnetic susceptibility measurements were taken from agricultural areas near the City of Maringá, in the Northwest region of the Paraná state, south Brazil, in order to characterize the spatial distribution of radionuclides (K, eU, and eTh), the apparent resistivity, and the magnetic susceptibility determined for soils. Three different types of soils are present in this agricultural area: Alfisoil, clayey texture Oxisoil, both deriving from Lower Cretaceous basalts of the Serra Geral Formation; and medium texture Oxisoil from reworked Serra Geral and Goio-Erê formations, the latter deriving from sandstones of the Upper Cretaceous Caiuá Group. It could be observed that in more clayey soils both concentration of radionuclides and susceptibility values are higher than in more sandy soils, especially due to the higher adsorption in the former and to the higher availability of magnetic minerals in the latter. The average ppm and Bq Kg −1 grades for K, eU, and eTh in the areas under anthropic activity are of 1766-54.75, 0.83-10.22, and 1.78-7.27, respectively. These grades are significantly higher than those of non-occupied or non-fertilized areas (1101-34.15 K, 0.14-1.69 eU, and 1.31-5.36 eTh in ppm and Bq Kg −1 , respectively.) Correlations were observed between uranium and clay, uranium and magnetic susceptibility, uranium and organic matter, and between electric resistivity and clay grades. Varied concentrations of radionuclides were also observed in different fertilizer formulations applied to soy and wheat cultures. Apparent electric resistivity values between 25 and 647 Ohm.m and magnectic susceptibility values between 0.28 e 1.10 × 10 −3 SI due to clay and magnetic minerals represented important soil discrimination factors in the study area that can be incorporated as easy, low-cost soil mapping tools.Keywords: Gamma-ray spectrometry, electrical resistivity, magnetic susceptibility, agriculture, soils, fertilizers. RESUMO. Medições gamaespectrométricas, de resistividade elétrica e de susceptibilidade magnética foram tomadas em solos agrícolas situados próximos a cidade deMaringá, noroeste do estado do Paraná, sul do Brasil, objetivando caracterizar a distribuição espacial das concentrações de radionuclídeos (K, eU e eTh), da resistividade aparente e da susceptibilidade magnética. Naárea agrícola ocorrem três tipos de solos: Nitossolo Vermelho Eutrófico, Latossolo Vermelho Eutroférrico textura argilosa, ambos derivados da Formação Serra Geral (basaltos do Cretáceo Inferior) e Latossolo Vermelho Distrófico textura média, oriundo do retrabalhamento das formações Serra Geral e Goio-Erê, estaúltima composta por arenitos do Grupo Caiuá (Cretáceo Superior). Constatou-se que as concentrações de radionuclídeos e os valores de susceptibilidade magnética nos solos mais argilosos foram maiores do que nos solos mais arenosos, em função, principalmente, da maior adsorção dos primeiros e da maior disponibilidade de minerais magnéticos. Os teores médios em ppm e Bq...
