Decision Sciences’ Multi-Mode Passive Detection System (MMPDS) combines 
technology invented by top government scientists at Los Alamos National Laboratory with considerable private sector investment and expertise, to deliver totally safe, effective and reliable automated scanning to speedily detect both shielded and unshielded nuclear and radiological threats. Additional modality enables explosive and contraband detection. Harnessing the natural occurrence of muons in the atmosphere, Decision Sciences’ MMPDS tracks muons through even heavily shielded materials and computes a 3-D image of what is being scanned. In combination with a gamma radiation detector, MMPDS can scan a typical 40-foot shipping container in 30 seconds, on average, providing accurate and safe scanning while facilitating the flow of commerce. The MMPDS technology produces no ionizing radiation, meaning it is completely safe for people, animals, plants and food. MMPDS modular construction enables the system to be scaled up or down to scan any type of vehicle, rail cars and cargo containers.
i-HLS ISRAEL Homeland Security
MMPDS satisfies the 100% scanning requirement recommended by the US 9/11 Commission and later adopted by the U.S. Congress.
With near-zero false alarms, the MMPDS promises to improve the safety, effectiveness and efficiency of cargo scanning operations around the globe while providing the global transportation industry with a cargo scanning solution that is accurate, efficient, safe, modular and cost-effective.

Technology Advancements
Decision Sciences continues to expand the capabilities of its original scanner. Through the addition of latent gamma-ray technology, the company has already increased the efficiency and effectiveness of the detector.
Applications
Decision Sciences’ MMPDS is ideally suited for seamless integration into critical infrastructure, ports, borders, and air and rail operations around the globe where there is an ever-growing need for efficient, accurate detection and deterrence of nuclear terrorist threats. Designed to be embedded within existing infrastructure or as a stand-alone application, Decision Sciences’ MMPDS can easily be scaled to fit a wide variety of applications.
It is easy to operate and makes scanning and locating threats very simple. An operator only need look at MMPDS display screen to see where, in 3-D, a threat has been located.
Key Technology
A key driver behind the success of Decision Sciences’ MMPDS is a technology called muon tomography. Muons are naturally occurring cosmic ray-induced particles that continuously rain down from the Earth’s upper atmosphere, harmlessly penetrating everything they touch. Decision Sciences’ MMPDS tracks these muons, detecting and recording their deflection signatures with advanced proprietary software and algorithms as they pass through an object within the MMPDS.
