EGR and Marinelli resin-matrix gamma sources

EGR gamma sources are sealed sources in which radionuclides are incorporated into a thermosetting resin, which is then cast into the container. Characterised in terms of water-equivalent activity, they are available in a range of volumes, activity levels and radionuclides.
    • Reduce the risks and constraints associated with using liquid sources
    • Obtain a source tailored to your container, volume, activity and radionuclide requirements
    • Gain flexibility through catalogue references and custom configurations
    • Plan source replacement based on the recommended service life
    • Choose a vial or Marinelli geometry suited to your measurement setup
    • Tailor the volume, activity and radionuclide to your application with standard or custom configurations
    • Benefit from sources characterised in terms of water-equivalent activity
    • Rely on radiological characteristics measured using NaI scintillation detectors or HPGe semiconductor detectors with traceable calibration
    A sealed alternative to liquid sources
    Customisable volumes, activities and radionuclides
    • Radionuclides are incorporated into a thermosetting resin, which is then poured into the container to form a sealed gamma source
    • Vial sources include types R, E, F, G and H, with volumes of 15 ml for type R, 50 ml for types E and F, and 500 ml for types G and H
    • Marinelli sources include types M, I, K and L, with respective volumes of 250, 450, 1,000 and 3,000 ml
    • Containers ranging from 10 to 3,000 ml are available on request
    • Standard activities are 5, 18, 37, 55 and 74 kBq
    • Activities ranging from 0.1 to 900 kBq are available on request
    • Standard radionuclides are ¹³³Ba, ¹³⁷Cs, ¹⁵²Eu and the 12ML01 mixture
    • Radionuclides ⁵¹Cr, ⁵⁴Mn, ⁵⁷Co, ⁶⁰Co, ⁶⁵Zn, ⁸⁵Sr, ⁸⁸Y, ¹⁰⁹Cd, ¹¹³Sn, ¹³⁴Cs, ¹³⁹Ce and ²⁴¹Am are available on request
    • The recommended service life is approximately two radioactive half-lives for metrological use and 10 years for physical integrity
