Supplying the UK’s defence sector
Today, the UK defence sector utilises the unique properties of lead in other ways, and Calder is a proud supplier of lead products used in a variety of defence-related applications.
Nuclear powered naval vessels need effective radiation shielding to protect the crew whilst using up the least amount of valuable space. Since the late 1950’s nuclear reactors have powered naval vessels, primarily the UK submarine fleet. Close confines and extended submerged periods mean that submariners rely on high performance shielding, to protect their health and safety whilst on active service. Our shielding ensures that these requirements are fulfilled.
An ever-changing world has increased the number and complexity of security checkpoints at airports, seaports, public buildings, border crossings and public venues. Calder supply shielding products that are incorporated into equipment that is protecting our national security and critical infrastructure, ensuring security professionals and the public are protected from radiation so that our safety and security can be maintained as people and property are passed through scanners and detection equipment. Our products are used in customised shielding solutions for x-ray inspection systems and other comprehensive detection technologies.
