Radiation safety training across NHS hospitals is widely delivered, but rarely proven. Staff attend lectures, complete e-learning modules, and meet compliance requirements. On paper, everything is in place. In practice, there is limited consistent evidence that clinicians can apply radiation protection principles during real procedures.
Under the Ionising Radiation (Medical Exposure) Regulations 2017, NHS Trusts are required to ensure the safe use of ionising radiation. However, most training models still rely on attendance rather than demonstrated performance.
That gap matters.
The Problem: Training Exists, Competency Is Assumed
Across the NHS, radiation safety training typically includes:
- Classroom teaching
- Online modules
- Annual compliance sign-off
These approaches confirm that training has been completed. They do not confirm that staff can perform safely in a live interventional environment.
If a Trust is asked to demonstrate that a clinician can:
- Minimise radiation exposure
- Position themselves correctly during fluoroscopy
- Use shielding effectively
There is often no objective evidence available.
This becomes a governance issue, not just an educational one.
Why This Matters in Interventional Radiology and Cath Labs
In interventional radiology and cardiology settings, radiation exposure is driven by behaviour.
Operator positioning, shielding use, and procedural decisions all influence dose. Research consistently shows that staff exposure is closely linked to patient dose and how procedures are performed (Durán et al., 2013; Vañó, 2003).
For teams aligned with British Society of Interventional Radiology expectations, the standard is not just awareness of radiation risks. It is the ability to manage them effectively during procedures.
Without assessing behaviour, training cannot reliably reduce exposure.
The Missing Piece: A Structured Competency Framework
What NHS radiation safety training lacks is a system that defines, measures, and records competency in a meaningful way.
A modern approach should include the following components.
Defined Competency Levels
Training should reflect clinical progression:
- Core: fundamental radiation protection principles
- Procedural: application during specific interventions
- Advanced: optimisation in complex scenarios
This mirrors how clinicians actually develop in practice.
Scenario-Based Assessment
Radiation safety is context-dependent. It cannot be assessed through static questions alone.
Clinicians need to demonstrate decision-making in realistic scenarios, including:
- C-arm positioning
- Shield placement
- Movement around the patient
- Response to high-dose situations
This is where immersive simulation becomes critical. It allows assessment in environments that replicate real procedures without introducing risk.
Objective Behavioural Metrics
Competency must be measurable.
Relevant metrics include:
- Distance from the radiation source
- Use and positioning of shielding
- Fluoroscopy activation patterns
- Time spent in high-exposure zones
These provide quantifiable evidence of performance rather than subjective judgment.
Measurable Outcomes
Training should produce clear, trackable improvements:
- Reduced simulated radiation exposure
- Improved positioning accuracy
- Faster recognition of unsafe conditions
Without outcome data, training remains an assumption.
Individual Audit Trails
NHS Trusts need defensible records.
A robust system should provide:
- Individual performance data
- Evidence of progression
- Documentation of assessed scenarios
This shifts training from compliance to accountability.
From Education to Governance
Current models answer a limited question:
Has this person completed training?
NHS Trusts increasingly need to answer a different one:
Can this person perform safely under pressure?
This distinction becomes critical during:
- Incident investigations
- Internal audits
- Regulatory review under IR(ME)R
Attendance records offer limited protection in these situations. Demonstrated competency does.
Why Simulation Changes the Model
Traditional training cannot replicate the complexity of interventional environments.
Simulation can.
It enables:
- Safe exposure to high-risk scenarios
- Repeatable assessment conditions
- Objective capture of behaviour
In radiation safety, this is essential. Real-world errors carry consequences, and high-dose scenarios cannot be practised safely on patients.
Simulation allows clinicians to demonstrate competency before entering those situations.
What NHS Trusts Are Beginning to Prioritise
To better align radiation safety training with clinical practice and regulatory expectations under Ionising Radiation (Medical Exposure) Regulations 2017, there is increasing focus on approaches that move beyond attendance-based models.
In practice, this includes:
- clearer definition of competency aligned to clinical roles
- greater use of scenario-based assessment
- more consistent measurement of behaviour during procedures
- longitudinal tracking of individual performance
- closer integration of training outcomes with governance and audit processes
Taken together, these approaches make competency more visible, measurable, and defensible.
The Direction of Travel
Across the NHS, radiation safety training is gradually shifting toward:
- performance-based assessment
- data-informed validation of practice
- stronger links between education and governance frameworks
Trusts that move in this direction are better positioned to demonstrate competency in a meaningful way, rather than relying solely on evidence of training completion.
At the same time, many organisations are still working within established models that meet formal requirements but can be harder to evidence under closer scrutiny.
Where This Can Be Applied in Practice
If you are reviewing how radiation safety training is delivered within your Trust, a useful starting point is to examine where competency is currently assumed rather than demonstrated.
This often becomes clear when looking at:
- how procedural behaviour is assessed
- whether performance data is captured at an individual level
- how training outcomes are used in audit or governance processes
From there, it becomes possible to identify where more structured, scenario-based approaches could strengthen both training and compliance.
Call to Action
If you are involved in radiation safety, education, or governance within an NHS Trust and are exploring how to move toward demonstrable competency, it is worth starting with a focused discussion rather than a full programme change.
We are working with clinical teams to:
- map existing training against competency requirements
- define measurable performance indicators for IR and cath lab staff
- design pilot scenarios with clear outcome thresholds linked to adoption
If that aligns with what you are trying to achieve, get in touch to arrange a short working session or pilot discussion.
