ISO-CART-II Mobile Assay System Cart

ISO-CART-II represents a generational advancement over previous models, with improvements in several areas:

  • Supports new and “legacy” spectrometry hardware
  • Lightweight materials used wherever feasible in the interests of maneuverability.
  • Adjustable front and rear track for extra stability even in tight spaces.
  • Easy assembled and disassembled for transportation.
  • Continuously and easily adjustable detector height and variable tilt adjustment. 
  • Unrestricted direct detector view of ground for soil assays.
  • New modular collimator system allows minimum weight configuration (ISO-CART-85).
  • Bottle counting option (ISO-CART-85)

    ISO-CART-II Mobile NDA Systems are ideal solutions for a wide variety of in-situ gamma-ray measurement requirements. The specially designed cart hardware transport system carries all the components: HPGe detector, shield and collimator, multichannel analyzer system, and laptop computer. The ISO-CART-II is entirely compatible with the latest generation of ORTEC integrated spectroscopy hardware and with spectrometry hardware which has been used with previous generations of ISO-CART.

    An ISO-CART-II system can provide everything necessary to produce quantitative results quickly and easily "right out of the box." The ORTEC ISOTOPIC software can control and process spectra from multiple ISO-CART systems assaying a single item, or can process results from multiple sequential views of the same item. The system can be supplied pre-calibrated at the ORTEC factory, 100% ready for use.

    With ISO-CART-II, the entire assay system is easily transported to any measurement location. The large wheels permit easy movement over rough surfaces. The detector support can be positioned at heights from 0.38 m (15 in.) to 0.91 m (36 in.). The pivot mechanism orients the detector at different angles from 0 to 180°. A sturdy adjustable shelf provides space for the notebook computer for convenient on cart operation. If the spectrometry system must be moved to a location where it is impractical to move the cart itself, it can be easily removed and carried. The collimator may be easily removed for infinite-plane soil measurements.
  • Basic Cart Specifications and Options +


    ISO-CART-II: Large wheels permit easy movement over rough surfaces. Detector support positioning: 0.38 m (15 in.) to 0.91 m (36 in.) H. Pivot mechanism orientation: 0 to 180°. Overall maximum dimensions: 1324 mm (52 in.) L x 889 mm (35 in.) W x 1300 mm (51.5 in.) H. Weight: 63.5 kg (140 lbs).

    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. 

    Turntable: Diameter: 30 in.; Rotation Speed: 1 rev/min; Capacity: 1000 lbs.; Height: 9.5 in.
