ESB gamma sources on paper filters

LEA’s ESB sources combine a paper substrate with a measured activity. Several configurations are available to meet your geometry and radionuclide requirements.
    • Use a source compatible with the dimensions of your equipment
    • Select an active area suited to your measurement configuration
    • Choose the activity and radionuclide appropriate for your application
    • Meet specific requirements beyond standard formats
    • Benefit from sources manufactured by depositing radionuclides onto a paper filter
    • Use a substrate sealed between two thin, heat-bonded polyester films
    • Rely on activity measurements performed using NaI scintillation detectors or HPGe semiconductor detectors
    • Request a configuration tailored to your active diameter, outer diameter, activity and radionuclide requirements
    Paper-filter sources sealed between polyester films
    Dimensions, activity and radionuclides tailored to your needs
    • Standard geometries have the following active/outer diameters: M43, 43/53 mm; M45-51, 45/51 mm; M47-53, 47/53 mm; M50, 50/60 mm; M53, 53/63 mm; M60, 60/70 mm; type 120, 120/130 mm
    • On request, active diameters range from 15 to 160 mm and outer diameters from 20 to 170 mm
    • Standard activities are 10, 20 and 40 kBq
    • Activities ranging from 1 kBq to 1 MBq are available on request
    • The standard composition is the 12ML01 mixture
    • Radionuclides available on request include ⁵¹Cr, ⁵⁴Mn, ⁵⁷Co, ⁶⁰Co, ⁶⁵Zn, ⁸⁵Sr, ⁸⁸Y, ¹⁰⁹Cd, ¹¹³Sn, ¹³⁴Cs, ¹³⁷Cs, ¹³⁹Ce and ²⁴¹Am
