Automatic Radioactive Detection and Measurement System


Automatic Radioactive Detection and Measurement System

The Gammasonics Automatic Radioactive Detection and Measurement System (ARDMS) detects the presence of radioactive material in a vehicle moving past the detector assemblies.

 

The same precise and proven technology developed by Gammasonics in Australia to identify human tissue contaminated by radio nuclide is now being applied to the new design of the ARDMS approach to protect the world
from illegal, unauthorised or criminal use of radioactive material.
The Gammasonics Automatic Radioactive Detection and Measurement System (ARDMS) detects the presence of radioactive material in a vehicle moving past detector system.
There is no need to stop the vehicle to check for radioactive sources. The detector assemblies are mounted vertically in a tower structure on both sides of the roadway. This provides full vertical coverage of the vehicle. Each detector is monitored separately, so that even if only one detector senses radiation it will compare this measurement to its own background level.
When a vehicle with a radioactive source passes between the detectors, the system sounds an alarm and display in the monitoring PC. The operator can then stop the vehicle and reject it or search for the source.

Applications

The system is composed of a highly sensitive scintillation detector with a high speed micro processing system, fixed to a strategic point, plus the AustralRAD Mini survey meter which allows for extremely sensitive and rapid monitoring to take place.

This unique combination brings the convenience of having a portable survey meter to the monitoring area which allows the operator to perform a detailed survey of the suspicious object.

The system is calibrated to area background levels and any changes in this constant will be considered a detectable event, activating visual and audible alarms. This indicates the presence of a radioactive isotope.
