  • Check Sources

    Ludlum offers a variety of check sources for use in verifying the operability of its instruments and detector systems. If you don't see what is needed here, please contact Ludlum.

    Plastic Disk Check Sources


    These are general purpose check sources that can be used freely to check responses from multiple instruments or be contained inside of Ludlum's mechanical check source holder (see below) that is directly attached to an instrument for convenience. The sources are sealed within a plastic disk.

    0.25 µCi 137Cs 2.5 cm x 3.2 mm (1.0 x 0.125 in.) 01-5723
    1.0 µCi 137Cs 2.5 cm x 3.2 mm (1.0 x 0.125 in.) 01-5196
    5.0 µCi 137Cs 2.5 cm x 3.2 mm (1.0 x 0.125 in.) 01-5186
    10 µCi 137Cs 2.5 cm x 3.2 mm (1.0 x 0.125 in.) 01-5231
    1.0 µCi 133Ba 2.5 cm x 3.2 mm (1.0 x 0.125 in.) 01-5818


    Plastic Laminate Check Sources with Stick-on Holder


    These sources are purposely designed to be attached to instruments.  They include a new very thin type plastic laminate source and an industrial strength adhesive holder for attaching directly to the instrument of choice.  The table below presents two of the more common sources. Other source activities and isotopes are available upon request.

    Plastic Laminate Check Sources with Stick-on Holder


    Ludlum's traditional mechanical type check source holder is screwed onto the instrument housing and has a nice swing-away door that exposes the source whenever needed.  This type holder is typically used with the Plastic Disk type check sources measuring 2.5 cm diamter x 3.2 mm thick (1.0 x 0.125 in.).  The part number is 4062-166.
