The threat of an attack using radiological and nuclear (RN) devices has consistently appeared in the National Risk Register, highlighting how these low-likelihood but catastrophically high-impact attack methods remain of concern to HMG.

To mitigate these risks, the Home Office maintains a comprehensive RN detection capability for passenger and freight traffic at the border.

This is known as the Cyclamen capability, which has been in operation since 2003.

It is the UK’s primary defence against the illicit importation of RN materials and sits alongside wider detection and response capabilities that make up the UK’s domestic nuclear security system.

Cyclamen is the UK's RN border detection system that plays a key part in protecting the UK border and is a critical part of HMG's Nuclear Security Strategy as well as CONTEST, the Government's counter-terrorism strategy.

Interested potential suppliers should visit the Home Office's eSourcing portal (Jaggaer) and look for: "PQQ_345 01 - Future Cyclamen: Non-Disclosure Agreement (NDA) for Early Market Engagement".

You should complete and submit the NDA following which we will invite your organisation to the Jaggaer site that contains our Selection Questionnaire documentation with more details about the Authority's requirements and how to participate.

For potential suppliers that have already completed the NDA, you will be automatically added to the Selection Questionnaire Event on the Home Office's eSourcing portal (Jaggaer) "pqq_484 - Future Cyclamen Selection Questionnaire".
