Summary: | The Radioactive Waste Management Department from IFIN-HH, Bucharest, performs the conditioning of the institutional radioactive waste in concrete matrix, in 200l drums with concrete shield, for final disposal at DNDR – Baita, Bihor county, in an old exhausted uranium mine. This paper presents a gamma-ray spectrometry method for the characterization of the radioactive waste drums' radionuclides content, for final disposal. In order to study the accuracy of the method, a similar concrete matrix with Portland cement in a 200l drum was used.
•An equivalent matrix of a 100l radwaste cemented in a 200l drum was measured.•Vertical channels for hosting standard sources were drilled in the concrete matrix.•Drum was measured with 152Eu sources placed in different configurations in channels.•Activity was calculated assuming a homogeneous radioactive matrix.•For photons with E>444keV computed activity is relatively close to certified value. |
