About Mobile Detect

Mobile Detect Inc. (MDI) provides cost-effective counter-terrorism technology solutions to protect airports, critical infrastructure, and communities from radiation threats.

Mobile Detect’s unique radiological surveillance networks measure radiation, distinguish between non-threats (like medical patients) and illicit radioactive substances, and visually present this information to security responders in real-time.

These networks of mobile and static radiation detectors are the only available radiological surveillance network that can identify even the faintest traces of radioactivity. The detectors, which each cover a radius of up to 400 meters, report radioactive readings to a central server. This data is interpreted in real-time to determine location-based threats, alert first responders, and provide authorities with a visual picture of the situation. Integration with existing security systems, email, PDAs and other wireless devices allows for instantaneous delivery of relevant information to first responders and decision makers.

Mobile Detect’s proprietary Targeted Automated Gamma Spectroscopy (TAGS) technology differentiates between medical-based radiation and illicit radiation in real-time. For example, MDI’s Airport RadWatch system is sufficiently sensitive to determine whether a passenger has recently undergone radiation therapy (medical treatment) or is attempting to smuggle an illicit radiological substance in carry-on luggage.

These systems can be deployed in various locations such as at airports, marine ports, installed in police cars, and integrated with traffic systems. The sensors and detectors are ruggedized for deployment in extreme environmental conditions.

Service is provided by a team of nuclear physicists and engineers with extensive government and private experience, with assistance from best-in-field suppliers. Detection systems can be purchased or leased directly from MDI.

Mobile Detect Products

MDI currently offers the following large protective systems:
Airport RadWatch: equipment deployed in airport, in vehicles, and with staff
Community RadWatch: equipment installed in Police (or other) vehicles
Facility RadWatch: equipment deployed in facility, in vehicles, and with staff
Marine RadWatch: equipment installed in Sea Ports locations, vehicles, vessels and buoys to augment the large radiation detectors present
Traffic RadWatch: equipment installed over roadways to provide low-resolution detection of 100% of traffic
TransitGate RadWatch: equipment deployed in gates at public transit stations
MDI offers the following small protective systems:
Bomb RadCheck and Bomb RadWatch: for Bomb Squads to recognize “dirty bombs” and provide “ground truth” after interruption/detonation
Portable RadCheck and Portable RadWatch: Networked person-carried systems for Event / VIP security
Vehicle RadCheck: Rapidly deployable single vehicle system for radiological incident investigation

Past Projects

Ottawa International Airport – Airport RadWatch
This project involves deploying MDI’s radiation detection equipment in static locations and vehicles at the Ottawa International Airport, reporting real-time measurements to MDI’s central server for analysis, storage and response.
National Capital Region – Community RadWatch
This project involves deploying MDI’s radiation detection equipment in the trunks of Ottawa RCMP vehicles, reporting real-time measurements to MDI’s central server for analysis, storage and response.
Colorado Springs - Traffic RadWatch
This pilot project involves installing MDI’s radiation detection equipment on traffic light poles in Colorado Springs. The equipment works as it does in the previous examples with the additional functionality that when an elevated level of radiation is detected, the equipment at that intersection directly signals traffic cameras to capture images of vehicles and people at the intersection.


Following the 9/11 terrorist attacks on the World Trade Center, Canada’s military, intelligence, and civilian agencies developed the Consolidated Risk Assessment (CRA) document to determine the potential risk of various types of terror attacks. The Canadian government subsequently established the Chemical Biological Radiological and Nuclear Research and Technology Initiative (CRTI) to invest in developing new technologies to close the security gaps identified by the CRA.

The CRA identified radiological terrorism to be a real threat to Canadian security. This is primarily because radiological substances, unlike fissile nuclear materials, are readily accessible (medical facilities, food irradiation plants, etc). Dr. McFadden, who had been Manager of Ontario’s Radiation Safety Program, was approached by CRTI to help develop new technologies to protect Canadian citizens from radiological threats.

Dr. Robert McFadden founded McFadden Technologies Ltd. in 2002, and later Mobile Detect Inc., developing and producing high-quality networked radiation detection systems. These systems were developed in cooperation with departments and agencies such as the RCMP, Health Canada, National Defence, Transport Canada, and the Ottawa International Airport.


United States and Canadian governments have identified radiological terrorist attacks as a significant security threat. Mobile Detect’s technology enables authorities to mitigate the risks posed by a potential radiological terrorist attack and improve public safety by providing the necessary tools to prevent, detect, and quickly respond to such an event.

CWID 2006, the US Joint Chiefs-event that evaluated 34 technologies by Military and Homeland Security agencies, reported that the MDI system is “easy to use, highly functional, and ready to be deployed in its current form”.

MDI’s radiation detection systems should play an integral role in North American counter-terrorism plans, a role that should be expanded as Canada and United States remain exposed to the threat of a radiological terrorist attack.
