Radiation & Specialist Signs

Radiation Specialist Signs are used to warn employees, contractors, visitors and authorised personnel about the presence of ionising radiation, radioactive materials and controlled radiation areas. These signs help communicate potentially serious hazards and support safe working practices in specialist environments.

Also known as radiation warning signs, radioactive hazard signs, ionising radiation signs and controlled area signs, they are commonly used where radiation sources, radioactive substances or specialist imaging equipment are present.

Radiation safety signage is widely used in hospitals, laboratories, research facilities, universities, industrial testing environments, nuclear facilities and specialist manufacturing sites. Common installation locations include controlled areas, X-ray rooms, isotope laboratories, storage areas and restricted access zones.

Manufactured in the UK, our radiation specialist signs are available in self-adhesive vinyl, rigid plastic and aluminium, providing clear and durable hazard identification for both internal and external applications.
