قياس تراكيز اليورانيوم في نماذج ترب بعض العيون الكبريتيةباستخدام كاشف الأثر النووي CR-39

Abstract

A concentration of uranium was measured in this study for seventeen samples ofsoil distributed in three Sulphuric Spring addition other regions as a back ground on theHit City in AL-Anbar Governorate. The uranium concentrations in soil samplesmeasured by using fission tracks registration in (CR-39) track detector that caused bythe bombardment of Uranium nuclei (U) with thermal neutrons from (241 Am-Be)neutron source that has flux of (5 ×103 n cm-2 s-1).The concentrations values were calculated by a comparison with standard samples.The results shows that the uranium concentrations in first spring varies from (1.564-2.253 ppm), second sprin (1.797-1.979 ppm), while in third spring are (1.964-2.518ppm), and the average uranium concentration in other regions (1.572ppm). Theconclusionshows that the uranium concentration in Sulphuric Spring is relativelyhigher than back ground.
