Arktis unveils new FPG detector

Posted 7 March 2019 · Add Comment

Radiation detection specialist, Arktis Radiations Detectors, has developed a new flat panel gamma (FPG) detector which is set to improve significantly the capability for detecting radioactive sources in a variety of applications.

The slim form factor of Arktis’ new detector means that gamma detectors can now be placed in areas where it was previously unfeasible or untenable for cost reasons. The modest size, weight and power requirements of the FPGs will increase considerably the locations where the detectors can be fitted. This type of detector allows operators to distinguish dangerous radioactive isotopes from benign ones.
 
The technology brings advantages to several market segments. FPGs can easily be fitted in security equipment that allows for the detection of radioactive sources, while one of the most intriguing concepts is 'Sensing Walls', where detectors are concealed behind walls or billboards.
 
Integration into other systems is enhanced by having signal processing on board the detector. Successful trials have already been carried out in drone applications, where sensitivity per payload is key. FPGs happen to be unbeatable in this metric.

Initial reaction to the development has been extremely positive. Arktis CEO Rico Chandra explained: “This year, sales of our Flat Panel Gamma (FPG) detectors have exceeded neutron detector sales for the first time. Our customers see FPGs as an enabling technology, opening the door to a whole range of applications. This includes tasks way beyond the detection of radiological threats.
 
“For some time now Arktis has pioneered in large area solid state radiation detectors. With FPG we have expanded our lead from neutron to gamma detection. I expect our advance to grow as our customers win business with their newly enabled products.”
