Kromek launches the D5 RIID high performance radiation
detector
World's smallest RIID with high accuracy and ultra-low false
alarm rate
Kromek (AIM: KMK), a worldwide supplier of detection technology
focusing on the medical, security screening and nuclear markets,
announces the launch of the D5 RIID, the world's smallest high
performance radioisotope identification device ("RIID"). The
ruggedised device, with ultra-low false alarm rate, is designed for
military, homeland security and industrial use.
The D5 RIID was developed under a programme with the Defense
Threat Reduction Agency of the US Department of Defense. It detects
a wide range of sources, including special nuclear material and
mixed, shielded and heavily masked configurations. It provides high
accuracy dose measurement and has an industry-leading ultra-low
false alarm rate of less than 1 in 24 hours. The D5 RIID combines
this advanced performance with being small, lightweight and
easy-to-use - capable of being operated in one hand. It can also be
used when wearing all levels of PPE, including gloves. It offers
multiple modes of configuration, including being able to provide
app-based training, and can be easily integrated into standard and
custom networks.
It is the first device to be launched in Kromek's new D5 product
range, which expands the Group's radiation detection portfolio to
encompass devices specifically designed for more challenging use
cases and harsh environments. This next-generation of product has a
larger crystal, which enables higher accuracy and sensitivity -
capable of detecting mixed, shielded and heavily masked
configurations including special nuclear material - as well as
being ruggedised.
Dr Arnab Basu, CEO of Kromek, said: "We are delighted to have
launched the D5 RIID, which truly sets a new benchmark in
radioisotope identification. The level of accuracy, combined with
small size, far exceeds competing military standard detectors,
enabling the rapid identification of radiological threats. As the
first of our new D5 range, this device expands our portfolio to
provide products ideal for use in harsh environments and for more
challenging applications alongside our existing D3 solutions that
are aimed at fleet deployment for large-scale networking across
urban areas. We are proud to be continuing to drive innovation in
this crucial area to enable rapid, informed decisions to be made in
response to a radiation threat wherever it may appear."
