Prerequisites / Co-requisites
The general properties of nuclei and radioactivity are studied, with an introduction to the deeper structure of elementary particles and the Standard Model. The nuclear physics includes alpha- and beta- and gamma-ray decay, nuclear fission and models of nuclear structure. The high energy physics includes the quark structure of hadrons, CPT conservation and CP violation and the impact of conservation rules on simple reactions of elementary particles.
give a basic understanding of why some nuclei are stable and others are radioactive and why they decay in the ways that they do.
introduce the concept of parity and how this quantum number, along with conservation of angular momentum, affects what physical processes will occur at the subatomic level.
give a general understanding of the different families of elementary particles believed to exist according to the Standard Model and how the quarks combine to form mesons and baryons.
introduce the effects of conservation rules (CPT, lepton number, baryon number, strangeness and charm…) on the interactions and reactions of elementary particles.
explain how to apply the understanding of nuclear and subnuclear processes to the solution of simple numerical problems and other problems related to nuclear and elementary particle reactions and decays.

Five laboratory sessions of 4 hours, in the radiation laboratory. Two two-week experiments and a one-week experiment. Experiments are designed to study the properties of various kinds of radiation and the methods for detecting them, including the spectroscopy (energy measurement) and absorption properties of alpha-, beta-, gamma, positron and x-radiation and neutrons
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
equip students with subject knowledge
develop skills in applying subject knowledge to physical situations
develop laboratory practical skills
develop scientific writing skills
The learning and teaching methods include:
33h of lectures and tutorials as 3h/week x 11 weeks
20h of laboratory work consisting of two 2-week experiments and one 1-week experiment
The assessment strategy is designed to provide students with the opportunity to demonstrate
recall of subject knowledge
ability to apply subject knowledge to unseen problems
ability to conduct laboratory experiments
communication of scientific ideas
Thus, the summative assessment for this module consists of:
An examination of 1.5h with 2 questions to be attempted from 3
marking the laboratory diary
a laboratory report or presentation mark
Formative assessment and feedback
Verbal feedback is given in the weekly tutorial sessions. Written feedback is given through the laboratory diary marking.
