|Assessment type||Unit of assessment||Weighting|
|Coursework||One hour long multiple-choice class test (WEEK 8). Ten questions.||30|
|Examination||1.5 HOURS END OF SEMESTER EXAMINATION||70|
The assessment strategy is designed to provide students with the opportunity to demonstrate their knowledge of concepts behind Radiation Physics.
Thus, the summative assessment for this module consists of:
A 1.5 hour duration examination paper that consists of 5 questions on Radiation Physics. Students will be asked to answer 3 questions from the 5. Full marks in the examination will be equivalent to 70 % of the total marks available in assessment of this module.
A multiple-choice class test in Week 8 . The class test will take one hour and will consist of 10 questions. This will make up 30% of the final module mark.
Formative assessment and feedback
Students will receive feedback on their performance in the take home written coursework test, each test being marked.
- To provide the student with a detailed understanding of the structure of matter, radioactivity and different types of ionizing radiation.
- To provide the student with the comprehensive understanding of basic phenomena in atomic and nuclear physics including atomic and nuclear structure, decay mechanisms, electromagnetic quanta, characteristic and continuous X-ray sources. To provide an understanding of radiation counting, nuclear and atomic spectroscopy equipment.
|1||Systematic understanding of the fundamental processes involved with the interaction of X- and gamma-ray photons, charged particles and neutrons with matter|
|2||Students be able to perform basic radiation shielding calculations and be aware of stopper power and attenuation data bases in the literature|
|3||Perform investigations of radiation sources and their interactions in media|
C - Cognitive/analytical
K - Subject knowledge
T - Transferable skills
P - Professional/Practical skills
Methods of Teaching / Learning
Formal lectures and occasional large group tutorial/question sessions. Teaching given by handouts, data projector and white board presentations and notes.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
