Transportable Radiation Analysis Counting System (TRACS)

Transportable Radiation Analysis Counting System (TRACS)


TRACS is an ultra-portable and complete analysis counting system for the detection and assessment of samples for gamma radiation contamination. The Genie-FieldPro counting interface and TRACS hardware are designed to work dynamically, bringing laboratory-quality measurements directly to the sample site. Samples can be placed inside the shielded counting chamber, counted and analyzed with a few quick steps, and cleared for the next step in the production process. In addition, quality assurance is guaranteed with several quality control features, traceability aspects, and ability to facilitate remote analysis by experts.

The TRACS Cart and Shield is the ultimate in portability and ease of assembly.  With each piece weighing less than 20 lbs (9kg), the TRACS Cart can be fully assembled in less than 10 minutes without the use of handtools  (click here to check out the video).  Once assembled, the unit provides a minimum of 1/2 inch (1.25 cm) of stainless steel shielding in the detector sample chamber, a shelf for the laptop computer, and locking wheels for rolling into the counting or local storage location.  Included also are a set of disposable shield liners in case of spillage or contamination in the sample counting cavity.

TRACS is designed for use with CANBERRA’s 2x2 inch room-temperature scintillator probes and the Osprey digital tube base MCA. The optimum detector is a temperature-stabilized 2x2 CeBr3 detector, which offers resolution of ~4% FWHM at 662 keV. Alternately, a stabilized 2x2 NaI or non-stabilized NaI or LaBr3 detector can be substituted (more about scintillators detectors).  The system includes a camera for capturing the image fill height of sample contents about to be assayed as well as a GPS device to record the location of the sample and the TRACS Cart at the time of measurement.   A fully-charged laptop is capable of powering the entire system (included detector and electronics) for hours of continuous counting, eliminating the need for an external power supply.
