Curricular information is subject to change.

The module will introduce radiation dosimetry, the types and general characteristics of radiation dosimeters and detectors and how they are used for dose estimations and image formation in the areas of health physics, medical imaging and radiotherapy. The lectures will review the physics of a variety of dosimetry approaches and the principles which form the basis of dosimetric measurement. The configurations and operation of ion chambers will be discussed in addition to their specific applications for calibration of devices. A range of relative dosimetry techniques will be examined, including thermoluminescent, film, optically stimulated luminescence, MOSFET, semiconductor and gel dosimetry. Furthermore, the lectures will introduce the design and operation of a range of commonly-used detectors, such as pulse-mode, scintillation and semiconductor detectors. The module will examine how radiation interacts with different detector materials, their particular detection characteristics and their specific applications in the areas of radiotherapy and diagnostic imaging physics.

About this Module

Learning Outcomes:

On completion of this module, students should have acquired a clear understanding of the different dosimetric approaches and detection techniques used in medical physics. Students should have acquired an appreciation of the principles of dosimetric and detector techniques and understand their characteristic responses to incident ionising radiation. Students should also acquire an understanding of their specific applications across health physics, medical imaging and radiation oncology.

The United Nations identified seventeen Sustainable Development Goals (SDGs) as core to the 2030 Agenda for Sustainable Development, and UCD contributes in general to SDG 4 Quality Education. Further SDGs explored within this module if relevant are listed below. A scale of 1 - 5 indicates the extent to which the SDG is covered.

Approaches to Teaching and Learning:
The module will combine lectures, group work and practical sessions. Students will be required to present the findings of their two practicals sessions in a group presentation. The module will also be assessed with an end-of term exam.

AI Usage:

Students may use generative AI tools for limited support in this module. Students may use AI for planning and researching their work, assisting with their presentations, refining the language of text they alone have authored or debugging their own code, but not to generate text, interpret results (including experimental data, simulations), solve assigned problems, generate presentations, formulate scientific conclusions or write the code required for computational assignments. Students remain fully responsible for the accuracy and reliability of their learning, and should be able to demonstrate their understanding of the work submitted during discussions with staff. Specifically, students are expected to be able to answer questions and explain and justify the theory, procedures, analysis and conclusions provided in their assignments and projects, as well as the structure and workings of any code used. For any assignment/presentation/project, students must include a statement that they had adhered to this AI usage statement, which is based on UCD guidelines, citing any AI tools used and (if requested) the prompts submitted.
