Understanding Veterinary Radiography Warning Lights

Vet X-ray warning lights are LED-based external indicators mounted outside access points to x-ray areas. These lights switch on immediately when the generator is active, indicating the space is a controlled radiation zone.

Fail‑To‑Safe Systems: Why They're Crucial

If the warning light system fails, safety-first circuits prevent the x-ray generator from activating. This stops exposure risks, maintaining operational safety.

Enhanced Signage with Two‑Stage Systems

Two-stage systems offer increased visual cues. A first light (usually amber) shows the area is restricted; a second light (red) appears only during exposure, displaying messages like “DO NOT ENTER” for clear communication.

Types of Veterinary X‑Ray Units

Mobile Solutions: Portability Without Compromise

Devices such as the VET‑20 are engineered for mobility and performance. Features include dual-laser alignment, remote exposure control, an LCD interface and a reinforced design — ideal for small-animal and mobile use.

Cubex Systems for Easy Transport and Quality Imaging

Cubex x-ray systems weigh approximately 13 kg and come with digital displays, soft-touch controls, and laser guidance. These units integrate seamlessly with digital imaging platforms, making them a convenient option.

Clinic-Based X‑Ray Infrastructure

For busy environments, options such as tabletop ZooMax systems or ceiling-mounted telescopic setups are available. These are suited for practices handling equine or mixed animal cases requiring advanced imaging.

Regulatory Guidance and Safety Requirements

Veterinary X-ray operations in the UK are governed by the Ionising Radiations Regulations 2017 (IRR17). Practices must ensure:

• Automatic warning indicators at all entry points, designed to fail‑to‑safe standards.


• Clear, accessible isolation switches located outside radiation zones.


• Up-to-date signage and written protocols, maintained by a designated Radiation Protection Supervisor (RPS).

Tips for Practice Owners

• Warning lights: Choose IRR17-compliant LED systems that are easy to recognise, even from a distance. Consider two-stage models for added clarity.


• X-ray systems: Portable options like the VET‑20 or Cubex are excellent for flexibility. Integrated systems may be better for high-volume environments.


• Installation: Collaborate with your RPS or a certified radiation adviser to ensure all components are correctly fitted and documented for compliance.

Veterinary X-Ray FAQs

What is “fail‑to‑safe”?

It ensures the x-ray unit won't activate if the warning system is not functioning.

Are dual-stage warning lights a legal requirement?

No, though they provide an extra safeguard during active use.

Can I use one system both in-clinic and on the go?

Yes. Models like the VET‑20 and Cubex are built for both field and practice settings.

How heavy are portable units?

The VET‑20 weighs approximately 9.8 kg; Cubex units weigh about 13 kg. Both are light enough for regular transport.

Do I need approval to install warning lights?

Installation must comply with IRR17 and be overseen by your RPS or a certified expert. Documentation and testing protocols are part of the process.

Wrapping Up

Reliable warning lights and x‑ray systems are at the core of safe veterinary radiography.
