The University of Jyväskylä, in collaboration with the Finnish Radiation and Nuclear Safety Authority (STUK), has developed a new type of handheld multi-purpose radiation detector that comprehensively detects all types of ionizing radiation. The device can be used by industrial and medical radiation users, regulatory authorities, the nuclear energy industry, first responders and military users. The technology has been patented and is currently being explored for commercialization.

The developed multi-purpose radiation detector can be compared to the Swiss Army knife, which packs a wide range of tools for many different uses into a small package.  

“The detector has versatile measurement capabilities,” says Principal Advisor Kari Peräjärvi from the Finnish Radiation and Nuclear Safety Authority (STUK), who is also a professor of practice in the field of radiation safety research at the University of Jyväskylä. “It enables the generation of comprehensive situational awareness in an unknown situation very quickly, which improves security. The small size and the possibility of various radiation measurements make work in the field easier, especially when it is not necessary to carry several different detectors.”
