Determination of the impurities concentration in tungsten, molybdenum, tin, and tellurium targets using neutron activation analysis techniques
The fast and k0-neutron activation analysis (k0-NAA)methods were used to investigate the radioimpurities concentration of 124Sb, 134Cs, 60Co, 87Rb, 182Ta, 233Pa, 65Zn, 56Fe, 110mAg, 51Cr, 95Zr, 75Se and 114mIn in the target samples WO3, MoO3, SnO2 and TeO2 which are needed for radioisotopes 188Re, 9...

| description | The fast and k0-neutron activation analysis (k0-NAA)methods were used to investigate the radioimpurities concentration of 124Sb, 134Cs, 60Co, 87Rb, 182Ta, 233Pa, 65Zn, 56Fe, 110mAg, 51Cr, 95Zr, 75Se and 114mIn in the target samples WO3, MoO3, SnO2 and TeO2 which are needed for radioisotopes 188Re, 99mTc, (113mIn and 117m Sn) and 131I production respectively at the Second Egyptian Research Reactor (ETRR-2). Experimental data, procedures and theoretical treatments were described. The concentrations of radioimpurities were determined and their sources either neutron capture reactions, or threshold reactions or both were identified. The
accuracy of the determined concentrations was checked using the IAEA Soil-7 reference sample. |
