Finnish scientists have unveiled a groundbreaking handheld device capable of detecting all forms of ionizing radiation, promising enhanced safety and efficiency across various sectors.
Key Points at a Glance
- Developed by the University of Jyväskylä and the Finnish Radiation and Nuclear Safety Authority (STUK).
- Detects alpha, beta, gamma, X-ray, and neutron radiation using multilayered Phoswich technology.
- Weighs less than two kilograms, combining five detectors into a single compact unit.
- Features directional gamma-ray sensing, a novel capability for devices of its size.
- Patented technology with plans for commercialization and broader applications.
In a significant advancement for radiation safety, researchers at the University of Jyväskylä, in collaboration with the Finnish Radiation and Nuclear Safety Authority (STUK), have developed a versatile handheld detector that identifies all primary types of ionizing radiation. This innovation stands to benefit industries ranging from healthcare and nuclear energy to emergency response and defense.
Dubbed the “Swiss Army knife” of radiation detectors, the device employs multilayered Phoswich technology, integrating five different scintillation materials into a single unit. This design allows for the simultaneous detection of alpha particles, beta particles, gamma rays, X-rays, and neutrons. The compact nature of the device, weighing under two kilograms, ensures portability without compromising functionality.
One of the standout features of this detector is its ability to directionally sense gamma radiation, a first for instruments of its size. This capability enables users to pinpoint radiation sources more accurately, enhancing situational awareness during inspections or emergency responses. Additionally, the detector can identify neutron radiation, crucial for detecting materials like plutonium and for characterizing neutron sources more precisely.
The Phoswich technology not only consolidates multiple detection capabilities but also simplifies the device’s electronics, contributing to its reduced size and weight. Future iterations may see further miniaturization, potentially incorporating silicon photomultipliers to replace traditional photomultiplier tubes.
Beyond its immediate applications, the technology holds promise for scalability. Plans are underway to adapt the detector for use in backpack-mounted systems, fixed monitoring stations, and integration with unmanned aerial or ground vehicles. The University of Jyväskylä and STUK have already filed for a patent and are seeking commercial partners to bring this technology to market.
This development also aligns with educational initiatives, supporting the upcoming Master of Science in Technology degree program in Safety and Risk Management at the University of Jyväskylä, set to commence in 2026.
