Overview

• The University of Jyväskylä and Finnish Radiation and Nuclear Safety Authority (STUK) have developed a patented handheld radiation detector using multilayered Phoswich technology.
• The device integrates five scintillation layers, enabling it to detect alpha, beta, gamma, neutron, and X-ray radiation in a compact, portable design weighing under two kilograms.
• Its directional sensing capability for gamma-rays is a novel feature, enhancing situational awareness and aiding in tasks such as detecting smuggled radioactive materials.
• The detector includes integrated digital electronics with a touchscreen for real-time monitoring and operates for approximately two hours on its current battery.
• Efforts are underway to commercialize the device, with potential applications in industrial, medical, and security sectors, alongside ongoing research into miniaturization and scalability.
