Docent lecture: Medical internal radiation dosimetry

Introduction. Internal absorbed radiation dose calculations in clinical routine are needed for evaluation of the health risks involved in the application of radiopharmaceuticals in diagnostic Nuclear medicine. Additionally, when using radiopharmaceuticals for therapeutic purposes, absorbed dose calculations serve to estimate the associated deterministic biological effect on the target organ or tumour. This lecture is part of the course “Physics of nuclear medicine” given in the fourth year of the Hospital Physics Master of science program at the Stockholm University. Intended learning outcomes. At the end of this lecture the students should be able to model the biological pathways of the radionuclides in the body, solve the differential equations that describe the activity distribution as a function of time and calculate the associated absorbed radiation doses to different organs or tumours. Teaching learning activities. To comply with these objectives, the lecture will be based on a student engaging challenge followed by a short lecturing and discussion in small groups. Finally a practical numerical exercise from clinical routine will be presented and discussed. The pedagogical idea behind this set of activities is to create a deep approach to student learning by promoting in-class collaborative learning. Therefore, my role as teacher in this specific lecture can be seen as “learning facilitator” to help the student in seeking meaning, relating ideas and use of evidence. Assessment tasks to measure learning outcomes. Individual student performance will be assessed at the end of the “Physics of nuclear medicine” course with a written examination. Grading criteria and type of examination questions will be clarified in a separate session. Feedback. Formative assessment to this specific session will be carried out at the end of the lecture using the “minute paper” concept. The student will write down (as concise as possible) the answer to the following two questions; Can you make a list with the most significant [central, useful, meaningful, surprising, disturbing] things you have learned during this lecture? Is there anything you did not understand?
