Large numbers of commercial shipping containers pass through ports-of-call, around the world. The detection of radioactive materials is an ultra-high priority. Entering and manually searching each container is not feasible. The shear numbers make such a task impossible. The RAD CanScan series effectively detect radioctive sources in a container, simply through a quick external scan.The RAD CanScan only requires access to one side of each container. It can even be used to scan stacked containers.

The Rad-7 CanScan, Rad-8 CanScan have two main elements: an 8ft tall by1 ft wide mobile detector column and the computer analysis console. Rad-9 CanScan includes a third element which is a neutron generator and requires a license to own and operate. These elements are available for mounting.

On an inspection truck which rolls along side the container, close and very slow.

On a crane which slides the Detector Column along the side of the container, or across the top of the container. The detector Column is available with rubber bumpers.

As a fixed horizontal boom or vertical tower, so containers can be pulled by it very slowly.

Rad CanScan Specifications:

Radiation Scintillators Rad-7 CanScan Rad-8 CanScan Rad-9 CanScan
Gamma 30 each, 3 in dia x 1 in Yes Yes Yes
Neutron 1 each, 5 in x 2 in x 2 in -- Yes Yes
Neutron Generator -- -- -- Yes

Neutron Generator: In the Rad-9 CanScan, a Neutron Generator gives enhanced sensitivity to fissile materials.
Shielding: Shielding and Collimation is provided, but may be deleted for special light-weight version: RAD-7LW.
Electronics: Each detector has pre-amp and HV.
Isotope Identification: A Multi-Channel Analyzer applies Background Subtraction and uses Sophisticated algorithms to compare the output from the highest counting detector to the extensive pre-loaded Spectrum Library to achieve accurate Isotope Identification.
Location Mapping: The computer uses the detector data to overlay a virtual 30 x 150 grid onto the shipping container, with grid lines spaced every three inches The visual display shows where the radiation emitting sources are Located on this grid.
Data Storage: All data is archived to the 100 Gig Hard Drive and automatically backed-up to CD.

Quantum Software

Complete gamma spectroscopy systems including analytical software is available. The Quantum Software packages have been designed for optimal user interface. This system is our latest innovation in the fields of pulse-height analysis and gamma spectroscopy. QuantumMCA provides support for a broad range of hardware with tools for qualitative analysis. QuantumGold adds full function quantitative analysis for nuclear spectroscopy to the features of Quantum MCA. QuantumGeD includes both qualitative and full quantitative analysis features for germanium detectors only (i.e., no NaI(Tl) detectors and no QCC mode). QuantumGe is the same, but without deconvolution analysis. QuantumNaID has both qualitative and quantitative analysis for NaI detectors only. while QuantumNaI does not include deconvolution analysis. Each version is a full 32-bit Microsoft Windows application, and will operate under Windows 95, 98, and NT version 4.0.

Multi-Channel Analyzer Graph

QuantumMCA is the basic MCA analytical package and is supplied with all of our multichannel analyzer instruments in this product line. For sodium iodide-based gamma spectroscopy, we offer the Quadratic Compression Conversion (QCC) (patent no. 5,608,222). It is implemented in the MCA2100R and MCA2100 gamma spectrometers. This signal processing technique gives spectra with consistent peak resolution throughout the entire range of detection. This makes spectrum analysis rapid and user-friendly.
