Explaining Vet X‑Ray Safety Lights

Veterinary X‑ray warning lights are external LED-based indicators placed at entry points to X‑ray rooms. These lights illuminate whenever the generator is in use, indicating that the area is subject to controlled radiation exposure.

How Fail‑To‑Safe Designs Prevent Exposure

Fail‑to‑safe designs ensure if a warning light or system malfunctions, the X‑ray generator will be disabled. This prevents the risk of accidental exposure, safeguarding both humans and animals.

How Two-Stage Warning Systems Improve Clarity

Two‑stage warning lights provide a more obvious signal between room status. The first light (usually amber) shows the room is restricted, and the second (red) signals active X‑ray use with phrases like “DO NOT ENTER”.

Veterinary X‑Ray Systems: Choosing What Suits Your Practice

Mobile Veterinary X‑Ray Systems

Portable models like the VET‑20 are intended for field and clinical use. Features include laser positioning, remote exposure, LCD screen, and resilience for transport — ideal for ambulatory work or small-animal clinics.

Cubex Systems for Lightweight Precision

Weighing approximately 13 kg, the Cubex range includes features such as digital displays, dual laser pointers, and easy pairing with digital imaging platforms. These systems combine precision with convenience.

Tabletop and Ceiling-Mounted Solutions

Integrated X-ray systems like the ZooMax are suited for in-house use. Larger or mixed-animal practices may choose ceiling-mounted, telescopic systems to handle equine or large-animal cases effectively.

Radiation Safety Obligations in the UK

Veterinary radiography must meet the standards of the Ionising Radiations Regulations 2017 (IRR17). Clinics are expected to provide:

• Warning lights at every access point that operate automatically and follow fail‑to‑safe design principles.


• Clearly labelled isolation switches located outside the radiation zone.


• Up-to-date radiation risk assessments, local rules, and guidance under the responsibility of a Radiation Protection Supervisor (RPS).

Helpful Guidance for Clinics

• Choosing the right lights: Opt for LED fail‑to‑safe lights visible from a distance and compliant with IRR17. Two‑stage lights are recommended for added clarity.


• System selection: Choose portable systems like VET‑20 or Cubex for versatility. Integrated setups may better serve high-volume or equine practices.


• Installation and documentation: Collaborate with your RPS or safety advisor to install correctly, and ensure all testing and documentation meet regulatory standards.

X‑Ray Safety and Equipment Questions

What does “fail‑to‑safe” mean?

It ensures exposure won’t occur if the system fails.

Are two-stage lights legally required?

Not mandatory, though they offer enhanced communication.

Can I use a portable X‑ray machine in both the clinic and the field?

Yes, both VET‑20 and Cubex models are multi-purpose for clinic and ambulatory care.

What is the weight of portable X‑ray units?

The VET‑20 weighs about 9.8 kg and the Cubex around 13 kg. Both are manageable for veterinary staff.

Do I need approval to install warning lights?

Yes, installations must follow IRR17 standards and be verified by your RPS or an authorised adviser. Proper planning and records are essential.
