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."
