INCORRECTLY SPECIFIED PARAMETERS OF THE CALCULATED CALIBRATION TEMPLATE AND THEIR IMPACT ON THE ACCURACY OF THE RADIONUCLIDE ACTIVITY MEASURED VIA GAMMA-SPECTROMETRY UNDER THE RADIOACTIVE WASTE PACKAGE CERTIFICATION PROCESS

The article discusses the impact of incorrectly specified parameters describing the configuration of gammaspectrometric measurements performed for RW packages when calculating the gamma-quanta registration efficiency on the measured specific activity of radionuclides. The study shows that due to incorrectly specified parameters, the measured specific activity of radionuclides in a RW package may differ from the true value by more than 100 times. The paper proposes some interlaboratory comparison tests to ensure the accuracy and reliability of gammaspectrometric measurements performed for RW packages using the calculated calibrations.

Keywords: radioactive waste, RW package, radiation characteristics, specific activity, gamma spectrometry, calculated calibration, registration efficiency, RW certification, interlaboratory comparison tests.
