    IMITATION OF STANDARD VOLUMETRIC ACTIVITY METAL SAMPLES by A. I. Zhukouski, A. O. Nichyparchuk, A. A. Khrutchinsky, S. A. Kutsen

    Published 2016-09-01
    “…Theoretical and experimental studies performed have shown the possibility to use imitators as a set of alternating point sources of gamma radiation and metal plates and their use along with standard volumetric activity metal samples for calibration of scintillation-based detectors used in radiation control in metallurgy. Response functions or instrumental spectra of such spectrometer to radionuclides like 137Cs, 134Cs, 152Eu, 154Eu, 60Co, 54Mn, 232Th, 226Ra, 65Zn, 125Sb+125mTe, 106Ru+106Rh, 94Nb, 110mAg, 233U, 234U, 235U and 238U are required for calibration in a given measurement geometry. …”
