Ukrainian Journal of Physics| Zusammenfassung: | A photoactivation method for determining the produced activities of 93Zr and 93Mo isotopes has been developed. The method consists of irradiating the metals and sorbents of radioactive materials produced at the Zaporizhzhya NPP with bremsstrahlung γ-quanta with an end-point energy of 18.5 MeV. From the measured γ-spectra and using the yield ratios for 99Mo, 58Co, and 89Zr isotopes, the 92Mo/59Co and 92Zr/59Co concentration ratios were determined. From the obtained data and the measured produced activity of 60Co isotopes in the studied specimens, the overall activities of 93Zr and 93Mo isotopes are calculated. |
