Real-time dosimetry is useful for regular use during interventions to provide insight into radiation exposure. By applying real-time dosimetry as part of a training concept, the added value becomes even greater. In this blog, we describe an example of a training concept around real-time dosimetry as it works well in practice.
Preparation
When you want to get started with a training setup around real-time dosimetry, it is important that the right colleagues are involved. In practice, we often see the following people participating:
- project leader
- radiology manager
- radiation expert / clinical physicist
- clinical physics employee
- radiologist / cardiologist
- radiodiagnostic technician
- other stakeholders
A next step is to install and configure the RaySafe i3: monitor and badges. This is in the run-up to the first phase: the baseline measurement. Also determine in which position the badge is worn: on or under the lead apron, on the shoes or on the glasses.
Baseline measurement
A baseline measurement is important to gain insight into the initial situation. Set the RaySafe i3 badges so that they are linked, but not shown on the monitor. This way you measure without anyone being influenced by the view of the dose. A period of 5 working days is usually taken for the baseline measurement, so that sufficient interventions take place. After these 5 days, evaluate the first measurement results.

Training
The evaluation of the baseline measurement is the starting point of the training phase. This consists of:
Theory
- refresh basic knowledge of X-rays / scattered radiation
- protective measures
- operation of the RaySafe i3
Practice:
- demonstration of protective measures with real-time dosimetry
Action plan
- work in duos that regularly work together
- draw up a radiation safety improvement plan per person, based on the baseline measurement and training
- agree with the duo partner that you will help and address each other
- present your action plan to colleagues
- discuss and evaluate the plan with your partner on a weekly basis
Evaluation
There are two evaluation moments in this process:
- interim evaluation: 4 weeks after the training
- final evaluation: 8 weeks after the training
Compare the results of both evaluations with the baseline measurement and draw conclusions and recommendations. The project leader or clinical physicist often plays a central role in this, by keeping track of the measured values. To what extent has radiation exposure been reduced?
