All-in-one gamma device helps security forces
detect radioactive sources at twice the speed, from twice as far
and with greater sensitivity to protect against nuclear threats
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.”
