Veterinary X-Ray Radiation Protection: IRR17 Compliance for UK Practices

What IRR17 requires of a veterinary practice with X-ray

If your practice takes X-rays, you are an employer working with ionising radiation, and the Ionising Radiations Regulations 2017 (IRR17) apply to you. In practice that means five things: register the work with the HSE, complete a radiation risk assessment, appoint a radiation protection adviser, set local rules with a radiation protection supervisor, and designate the X-ray area as controlled or supervised.

Each of those is a specific legal duty, not a recommendation. None of them is satisfied by buying lead aprons and a good X-ray machine. This guide works through what each one actually requires, in the order a practice manager would tackle them.

It is worth being clear at the outset that veterinary radiography is one of the most commonly cited compliance gaps when the HSE inspects veterinary premises — and the failings are usually the paperwork duties (risk assessment, training, local rules), not the equipment.

Register with the HSE — don't apply for consent

There are three tiers of permission under IRR17: notification, registration, and consent. Routine diagnostic radiography sits in the registration tier.

Under Regulation 6, "all practices are registrable practices except those listed in paragraph (2)", and an employer "must not carry out a registrable practice unless that employer has applied for, and has been issued with, a registration." The HSE is explicit that this covers veterinary X-ray: its guidance on work requiring registration lists "X-ray devices used by dentists, vets, chiropractors and NHS trusts" as work where "you will need to apply for a registration to work with a radiation generator unless you use it for work that requires consent." So you must register with the HSE before you start, and you should hold the registration confirmation on file. (New registrations are made through HSE's online RADAN service.)

A common confusion is over the consent tier. Consent under Regulation 7 is reserved for higher-risk practices — for example "the deliberate administration of radioactive substances to people or animals for medical or veterinary diagnosis, treatment or research". That covers nuclear scintigraphy and radioiodine work, not the plain diagnostic radiography that most small-animal practices do. If your practice only takes diagnostic X-rays, you need registration, not consent. Getting this wrong wastes time on the wrong HSE process — so confirm which tier your work falls into before you apply.

Complete a radiation risk assessment

This is the duty most often found missing on inspection. Regulation 8 requires an employer to "make a suitable and sufficient assessment of the risk to any employee and other person for the purpose of identifying the measures the employer needs to take to restrict the exposure". The assessment has to be done before you begin a new activity involving ionising radiation.

A vet-specific radiation risk assessment should cover at least:

• Who is exposed — the vets and nurses positioning and restraining patients, anyone in the room during exposure, and members of the public in adjacent areas
• The exposure pathways — primary beam, scatter from the patient and table, and leakage from the tube housing
• The work patterns — how many exposures per day, manual restraint versus sedation and sandbags, portable versus fixed equipment
• The controls — distance, shielding (aprons, gloves, thyroid shields, mobile screens), and the use of personal dosimeters
• Contingency — what happens if a patient moves, or if equipment faults mid-exposure

The assessment is not a one-off. Review it when you change equipment, change rooms, or change how you restrain patients (moving from manual restraint to chemical restraint materially changes staff dose). This sits naturally alongside your other veterinary risk assessments — radiation is one hazard category within a wider risk-assessment programme, not a separate silo.

Appoint a radiation protection adviser (RPA)

Regulation 14 requires that "every employer engaged in work with ionising radiation must consult such suitable radiation protection advisers as are necessary" and, where one is appointed, "the employer must appoint that radiation protection adviser in writing and must include in that appointment the scope of the advice".

In practice this means engaging an external RPA — a specialist, not a member of practice staff. The RPA helps with the risk assessment, advises on local rules and area designation, reviews your dosimetry results, and is the person the HSE will expect you to have consulted. Two things matter for compliance: the appointment must be in writing, and it must state the scope of the advice. A verbal arrangement or an unwritten understanding does not meet Regulation 14.

Set local rules and appoint an RPS

Regulation 18 covers local rules and radiation protection supervisors. Local rules are the practice's written working procedures for the X-ray area — who may operate the equipment, how patients are restrained, where people stand during exposure, what PPE is worn, and what to do in a contingency. They must be specific to your practice, not a generic template, and every person who works with radiation must know them.

The radiation protection supervisor (RPS) is an internal role — usually a vet or senior nurse — responsible for making sure the local rules are followed day to day. Unlike the RPA, the RPS is one of your own team. The RPS needs training appropriate to the role; "I appointed myself last year" without training is a finding waiting to happen.

Designate the X-ray area

Regulation 17 requires designation of controlled or supervised areas. For most practices the X-ray room is a controlled area during exposures — entry is restricted, signage is in place, and the local rules govern who may be present. The designation flows from the risk assessment and the RPA's advice: the assessment defines the dose risk, the RPA advises on the boundary, and the designation makes it a managed area with rules attached.

Practical signs of a properly designated area: warning signage and lights, a defined boundary, restricted entry during exposure, and dosimetry for staff who work in it regularly.

Where practices most commonly fall short

When veterinary premises are inspected for radiation compliance, the recurring failings reported by the regulator and by radiation consultants are consistent — and they are almost never about the X-ray machine itself:

• No radiation risk assessment, or an inadequate one — the Regulation 8 duty not met
• No, or out-of-date, training for the RPS and for staff taking X-rays
• Generic local rules copied from a template rather than written for the practice
• Manual restraint as the default — increasing staff dose unnecessarily where sedation and positioning aids would reduce it
• No dosimetry for staff who are regularly in the room during exposures

If you fix one thing first, fix the risk assessment — it is both the most commonly missing duty and the foundation everything else (local rules, area designation, training needs) is built on.

A practical compliance sequence

If you are starting from a standing start, work in this order:

1. Engage an RPA in writing, with a defined scope — they will guide the rest
2. Register the work with the HSE under Regulation 6
3. Complete the radiation risk assessment with RPA input
4. Write local rules specific to your X-ray area
5. Appoint and train an RPS to enforce the local rules
6. Designate the area as controlled (or supervised) per the RPA's advice
7. Set up dosimetry for regularly exposed staff
8. Schedule a review — annually, and on any change of equipment, room, or working practice

How radiation compliance fits the wider picture

Radiation protection is one stream in a practice's non-clinical compliance programme, sitting alongside COSHH, clinical waste, and controlled drugs. The same disciplines apply: a documented assessment, named ownership, written procedures, training records, and a review cycle.

It also feeds your clinical governance framework — the radiation risk assessment, RPA appointment, and dosimetry results are all evidence the framework should hold and review. And because the RCVS Practice Standards Scheme assesses health and safety, your radiation paperwork is part of what a PSS assessor will expect to see.
