PHY209 Radiation Physics (8)


In this subject physical concepts and laws are introduced relating to radiation generation and interaction, along with mathematical and computational methods used in describing the behaviour of radiation.
Broad areas of study include: Concepts of modern physics, elementary nuclear physics, radiation generation and interaction, radiation metrology, introduction to dosimetry, applicable mathematical methods, and radiation counting statistics. Elementary computational work in radiation physics using readily available spreadsheet software is also undertaken.

Learning Outcomes

Upon successful completion of this subject, students should:
solve problems of a conceptual, numeric or symbolic nature in the specific individual syllabus areas;
relate concepts and physical laws to phenomena involving radiation in an exact, specific, and accurate fashion, and demonstrate such an ability in the solution of problems; and
deduce appropriate analytical and/or computational methods to fulfil both of the above objectives.
