An Overview of X‑Ray Warning Lights in Veterinary Practices

Veterinary X‑ray warning lights are control area signals placed at entry points to X‑ray rooms. These lights switch on 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 guarantee if a warning light or system malfunctions, the X‑ray generator will be disabled. This eliminates the risk of accidental exposure, safeguarding both humans and animals.

Benefits of Dual‑Stage Warning Lights

Two‑stage warning lights provide a stronger visual separation 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”.

Portable to Integrated: X‑Ray Options for Vets

Portable Imaging Solutions

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

Compact High-Frequency Units: Cubex Range

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 are efficient and compact.

Integrated Digital Systems for Clinical Settings

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 manage high patient volume effectively.

Radiation Safety Obligations in the UK

Veterinary radiography must meet the standards of the vet xray systems 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).

Best Practice Recommendations

• 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.
