Learning outcomes

# Learning outcome
1

Formulate designs and advice for radiation installations.
2

Critically appraise the risks and safety requirements associated with ionising and non-ionising radiation.
3

Perform and interpret measurements of radiation, draw conclusions on adequacy of control measures and advise on further action.
4

Calculate estimated radiation doses, evaluating the limitations and uncertainties of the approach.
5

Investigate radiation overexposure and incidents and make recommendations for remedial actions and further reporting.

Clinical experiences

Clinical experiences help you to develop insight into your practice and a greater understanding of your specialty's impact on patient care. Clinical experiences should be included in your training plan and you may be asked to help organise your experiences. Reflections and observations from your experiences may help you to advance your practice and can be used to develop evidence to demonstrate your awareness and appreciation of your specialty.

Activities

  1. Attend a site check during construction or installation of new radiation equipment.
  2. Observe the calibration and testing of radiation instruments and monitoring equipment.
  3. Shadow the follow up and investigation of a radiation incident.
  4. Observe patient treatment with laser/phototherapy.

Academic content (MSc in Clinical Science)

Important information

The academic parts of this module will be detailed and communicated to you by your university. Please contact them if you have questions regarding this module and its assessments. The module titles in your MSc may not be exactly identical to the work-based modules shown in the e-portfolio. Your modules will be aligned, however, to ensure that your academic and work-based learning are complimentary.

Learning outcomes

On successful completion of this module the trainee will be able to:

  1. Demonstrate extended understanding of the principles of operation and use of a range of radiation measuring equipment.
  2. Apply integrative knowledge of radiation protection principles and legislation to the design of radiation facilities.
  3. Apply integrative knowledge of legislative requirements or guidance within diagnostic radiology, nuclear medicine, radiotherapy and non-ionising radiation practices.
  4. Discuss investigation of an incident involving radiation exposure to a patient or member of staff, including assessment of radiation dose and risk.
