ISO-CART-II LN2 Mobile Assay Systems


ISO-CART-II systems may be configured with a wide variety of ORTEC liquid nitrogen cooled, HPGe radiation detectors from which relative efficiencies of over 200% are available. The portable HPGe radiation detector is mounted, along with the chosen collimator on the detector/collimator carrier or “DCC” which is easily removable from the cart as a unit.

If the radiation detector must be moved to a location where it is impractical to move the cart, the detector/collimator unit can be removed and carried.

    Dewar Options
    A portable, all-attitude HPGe radiation detector is available with a 3.0-liter Gamma Gage dewar. A 7.0-liter multi-orientation dewar (MOD) is also available. The MOD dewar allows near all attitude use while offering reduced size compared to the equivalent holding time Gamma Gage model. Typically, the HPGe radiation detector chosen would be a large volume GEM (P-type) or GMX (N-type); however, a wide variety of radiation detector choices are available. Standard systems may be ordered by model number. Contact us to suggest a configuration according to your radiation detection limit and count-time requirements.

    SHD-1 Shield/Collimator: The standard collimator is 1.6 cm (0.625 in.) thick and 20.3 cm (8 in.) long. It is composed of lead with a 2 mm (0.08 in.) copper liner. Complete shield dimensions: 26.42 cm (10.4 in.) H x 20 cm (8 in.) W x 77.5 cm (30.5 in.) D. Weight: 16.82 kg (37 lbs).

    SHD-2 Shield/Collimator: The medium-duty collimator is 1.3 cm (0.5 in.) thick and 20.3 cm (8 in.) long. It is composed of a tungsten-copper alloy for better shielding characteristics while maintaining a small volume assembly. Complete shield dimensions: 26.68 cm (10.5 in.) H x 2 cm (8 in.) W x 77.5 cm (30.5 in.) D. Weight: 27.27 kg (60 lbs).

    SHD-3 Shield/Collimator    : The heavy-duty collimator is 4.6 cm (1.8 in.) thick and 20.3 cm (8 in.) long. It is composed of heavy duty lead for high radiation areas. Complete shield dimensions: 25 cm (9.75 in.) H x 20 cm (8 in.) W x 77.5 cm (30.5 in). D. Shield is split in two sections for assembly purposes. Weight: 68 kg (150 lbs).

    Laser Meter    : The Laser Meter accurately determines the distance from the detector endcap to the measurement point. A sighting laser mounted on the collimator is used to center the detector on the measurement point. The range finder can be set to display the distance in meters or feet. 18.8 x 7.0 x 4.7 cm (7.4 x 2.8 x 1.9 in.). Accuracy: 3 mm. 

    digiDART™ Data Acquisition Hardware
    The digiDART is an ideal MCA for use with an in-situ assay system. It can acquire preliminary data in the field as a stand alone unit or perform a complete analysis on the spot with the use of a notebook computer.

    To fully specify your choice of ISO-CART-II system, select the model number below for the size of detector needed and replace the letters DDD in the model number with the desired choice of dewar, as follows:  3.0 = 3.0-liter Gamma Gage dewar or M7L = 7.0-liter MOD dewar

    Other configurations may be supplied on request. Your existing detectors may be used. Contact your ORTEC representative or e-mail ortec.info@ametek.com with your requirements.
