EGR γ sources in resin matrix

Radionuclides are incorporated into a thermosetting resin, which is then poured into container.

Our resin sources are sealed sources and are characterized by water equivalent activity, to avoid risks and constraints associated with liquid sources. The radiological characteristics of the sources are measured with calibrated Nal scintillators or HPGe semi-conductors.

** The 12ML01 mixture – Am-241, Cd-109, Ce-139, Co-57, Co-60, Cr-51, Cs-137, Sn-113, Mn-54, Zn-65, Sr-85, Y-88 – generates around 15 peaks over an energy range from 60 keV to 1836 keV. The quantity of each radionuclide is chosen so that the counting rates of the main peak of each radionuclide are the same order of magnitude. See below for additional information on the 12ML01 mixture and on the other mixes available. Other geometries are available on request.
