The structural materials from the 2nd unit of the Chornobyl NPP were irradiated by bremsstrahlung photons with an end-point energy of 37 MeV. From the measured y-spectra, using the ratios among the 57Co, 54Mn, and 58Co activities, the concentrations of 58Ni and 56Fe isotopes were determined in compa...
