Radionuclide Calibrator Course

Radionuclide Calibrator

The Radionuclide Calibrator e-Learning Course has been designed to support the effective use of radionuclide calibrators, in a clinical setting. It delivers the right skills and strategies when operating them, and provides a methodological approach when implementing quality assurance tasks, and identifying sources of uncertainty.

Main Objectives

  • To maximise the accuracy of activity measurements in hospitals, leading to better outcomes for patients
  • To help meet nuclear medicine competencies, and thus comply with regulations
  • To improve quality assurance processes, leading to increased confidence in radionuclide calibrator performance
  • To improve assessment of processes and outcomes, through enhanced understanding of measurement uncertainty

Learning objectives

  • Understand the operation of a radionuclide calibrator and its constituent parts
  • Understand the term calibration factor
  • Explain the factors affecting the response of an ionisation chamber
  • Use the specifications of a range of radionuclide calibrators to recommend the most appropriate in a given situation
  • Understand the importance of traceability to activity measurement
  • Understand the calibration of secondary standard radionuclide calibrators against primary standards, and field instruments against reference instruments
  • Use a range of strategies to derive calibration factors and dial settings, taking into account the geometries of source and chamber
  • Use copper filters appropriately in the measurement of beta-emitters and low-energy gamma emitters
  • Be able to perform a range of acceptance and Quality Assurance tests, including linearity, repeatability and accuracy
  • Identify the main sources of uncertainty in radionuclide calibrator measurements
  • Evaluate measurement uncertainty in a given situation for a radionuclide calibrator
