Kromek Launches The D3 PRD High-Accuracy Personal Radiation Detector

SEDGEFIELD, ENGLAND--(BUSINESS WIRE)--

Kromek Group plc (“Kromek” or the “Group”) (AIM: KMK), a worldwide supplier of detection technology focusing on the medical, security screening and nuclear markets, is pleased to announce the launch of the D3 PRD, the new all-in-one, high-accuracy personal radiation detector (“PRD”) for first responders, armed forces, border security and CBRNE experts.

The D3 PRD continuously monitors gamma radiation levels, equipping security forces to protect against the threat of nuclear terrorism and the illicit movement of nuclear materials. Built to meet the requirements of the PRD market, it expands Kromek’s existing range of wearable radiation detectors. The D3 PRD is an all-in-one device, with replaceable batteries and which fits into a conventional use model of PRDs. It measures and notifies users of gamma dose while also storing spectral information that can be downloaded and analysed offline by a trained user if required.

The new product combines a small form factor (pocket-sized) with a detector substantially larger than that of some competitors. It allows users to detect radiation at twice the speed, from twice the distance and with greater sensitivity (detecting material at half the strength) than the current state-of-the-art detectors. The built-in screen notifies users of radiation with a high dose accuracy of ±10% and it has an industry-leading ultra-low false alarm rate that is more than six times better than the ANSI standard determined by the US government.

In addition, Kromek’s CIRIS configuration software allows users to tailor the device settings for specific applications, including adjusting the threshold for alarms. The E-Learning platform allows users to benefit from on-the-go interactive training to ensure all frontline workers can be easily equipped with the device.

Dr Arnab Basu, CEO of Kromek, said: “We are very pleased to be deepening our footprint in the personal radiation detection market and expanding our wearable range. The new D3 PRD meets a growing market demand for a standalone gamma-only device, while offering market-leading dose accuracy, speed to alarm and an ultra-low false positive number. Built with ease-of-use in mind, the device can be tailored to specific applications and worn by all frontline workers, helping to ensure our towns and cities are protected against nuclear threats.”
