These customers used a heavily shielded GR1 to measure the radioactivity levels in a building at the Fukushima Daiichi power station.
The Kromek GR1 is a range of CZT-based high-performance gamma-ray spectrometers. They are completely self-contained, with a built-in preamplifier, shaping amplifier, baseline restorer, pulse height digitizer, and HV supply. The digitized pulse heights of detected gamma-ray signals are sent to a PC via the USB. The unit is powered entirely from the USB bus, so no external power supply is needed.
Kromek Group plc designs, develops and produces x-ray and gamma-ray imaging and radiation detection products for the medical, CBRNe security, Homeland Security and civil nuclear radiation detection markets.
