Analysis of Naturally Occurring Radioisotopes in Peat moss Greenhouse Soils and Agriculture Mud in Egypt

Abstract

In this work, the activity concentrations (radioactivity) and distributions of natural radionuclides in peat moss samples were investigated. The measurements were performed using HP-Ge detector and XRD technique. The samples represent six types of soils. The concentrations of radionuclides of 238 U, 226 Ra, 232 Th and 40 K are ranged from 17.14 to 130.83, 13.19 to 26.09, 5.33 to 25.2 and 143.26 to 600.31 Bq•kg-1 (dry weight), respectively, for the different samples. This work also highlights that no correlation has been observed between radionuclides present in the samples, which in turn reflects the random method

New Aspects of Uranium Ore Concentration by using Acidic Media Solutions

“…The detector has a photo‐peak relative efficiency of about 50 % of the 3“×3” NaI (Tl) crystal efficiency. The efficiency calibration was performed by using three well‐known reference materials obtained from the International Atomic Energy Agency for U, Th, and K activity measurements: RGU‐1, RGTh‐1, and RGK‐1 [15,16] …”
