Reflective practice guidance
The guidance below is provided to support reflection at different time points, providing you with questions to aid you to reflect for this training activity. They are provided for guidance and should not be considered as a mandatory checklist. Trainees should not be expected to provide answers to each of the guidance questions listed.
Before action
- How does calculating absorbed radiation doses contribute to your ability to apply the principles of internal radiation dosimetry?
- What broad guidance might be relevant here?
- What is the specific aim of this calculation exercise?
- Is it to understand the methodology, interpret the results, or relate the doses to potential effects?
- Consider the specific insights you hope to gain from performing these dose calculations. What aspects of internal radiation dosimetry do you want to understand better (e.g., the models used, the input parameters, the uncertainties)?
- Think about what you already know about radiation dose calculations. What are the areas where you feel less confident or have questions?
- What practical skills in applying dosimetry principles and using relevant tools or software do you hope to develop?
- Discuss the specific requirements of this training activity with your training officer.
- Will you be provided with specific patient data or scenarios?
- What tools or methods are expected?
- Consider possible challenges you might face, such as understanding the required data, selecting the appropriate models, or performing the calculations accurately. How might you prepare for these challenges (e.g., reviewing relevant theory, practicing with examples)?
- Identify how you feel about performing these calculations. Do you feel prepared or do you anticipate needing significant support?
- What resources might be helpful to review beforehand?
In action
- Pay attention to the steps you are taking in the calculation process.
- Why are you choosing this particular methodology or formula?
- What decisions are you making about the input parameters and their values as you perform the calculation?
- What aspects of the calculation feel intuitive based on your understanding of internal radiation dosimetry, and what requires more conscious effort and referencing?
- How confident are you in the accuracy of your calculations as you proceed?
- What challenges are you facing during the calculation, such as identifying the correct parameters or performing the mathematical steps?
- What can you learn about the principles of internal radiation dosimetry as you work through this specific calculation?
- How does this calculation relate to your understanding of radiation protection principles?
- Are there alternative approaches or tools you could use to verify your calculations or if you encounter difficulties?
- What support or guidance might you need if you are unsure about certain steps or parameters?
- Are you working within the scope of your current knowledge and seeking appropriate supervision if needed?
On action
- What were the key steps and parameters involved in the dose calculation?
- Were there any points in the calculation process where you felt more or less confident?
- What were the final absorbed dose values for the target and non-target tissues?
- What did you learn about the principles of internal radiation dosimetry through this calculation?
- Did you encounter any unexpected challenges in identifying the correct parameters or performing the calculation? What did you learn from these challenges?
- How did your reflect-in-action (during the calculation) help you to identify and correct any potential errors or uncertainties?
- How does this experience relate to the requirements for understanding and applying internal radiation dosimetry in post-programme practice?
- What areas for continued development in your understanding or application of internal radiation dosimetry have been identified?
- How can you apply the learning from this calculation to future scenarios involving radionuclide therapies?
- What specific actions will you take to enhance your skills in dose calculation?
- What support or resources might you need to further develop your knowledge and skills in this area?
Beyond action
- Have you looked back at your initial reflections on performing these dose calculations?
- Have you since performed other dose calculations (perhaps in other training activities or other learning activities)?
- How does your understanding and approach to these calculations now compare to this initial experience?
- Have you discussed the principles of internal radiation dosimetry with colleagues? Has this broadened your understanding of the concepts involved in this training activity?
