EDC γ sources in charcoal filter cartridges

Our active charcoal can be impregnated in two ways:

• • Surface impregnation, a radioactive disk is placed in contact with one of the inside surfaces of the housing to simulate surface contamination (E geometry)
  • Pore volume impregnation, the activated charcoal is homogeneously impregnated (D geometry)

Source activity is measured with calibrated Nal scintillators or HPGe semi-conductors.

Standard manufacturing tolerance: ± 30% | IAEA Category: 5 | ISO2919 Classification: C11111

* 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.
