Assessment Brief

Component A is an exam in two parts. Part 1 will be in January and is 75 multiple choice questions in 60 minutes, covering basic radiation physics only

Part 2 of the exam will be in April and is also 75 multiple choice questions in 60 minutes, covering Diagnostic Imaging/Radiotherapy equipment and the imaging modalities. 

See below for last year’s exam papers, but you should be aware that the format this year has been changed in order to help your learning and understanding by dividing the exam into these two parts.  Other previous exam papers are available through the Library intranet site

The results from the two exams will be added together and then percentaged, so if you do not do well in part 1, you can make up for it in part 2. 

The whole exam carries a weighting of 70% of the final module result.


Component B is a written assignment, in the form of a report of 2000 words.

 The report will be a write up of two investigations you will carry out in your practical sessions that follow the exam in January:

 1 To investigate the effect of the inverse square law on a beam of x-ray photons

 2 To investigate the attenuation with thickness of material of a beam of x-ray photons


Report guidelines


Your report must be word processed and should be identified by your student number, not name. Please use a standard font such as Arial and font size of 12. A line spacing of 1.5 helps readability. Page numbers are helpful.

Before you do your practical and particularly when you write up your report, you will need to do lots of background reading – lecture notes should be a starting point but should not be used as references. You should use sources of information from your reading of textbooks, appropriate peer-reviewed journals and reputable websites. 

Once you have decided what to include, put this into your own words to show your understanding; then add the appropriate reference to acknowledge your source. If you use other people’s words by lifting sentences or paragraphs from books etc, without acknowledging it as a quote, you run the risk of plagiarism, a serious assessment offence.   But use quotes sparingly, only to emphasise a point or where to paraphrase would lose the meaning.

You should organise your report under the following headings:


Gives the theoretical background to the investigation, using published sources of evidence such as textbooks and reputable internet sites, appropriately referenced.


Repeats the instructions provided for the investigation, but you may wish to include diagrams/images and to expand the method if necessary or where it was modified and why.


Clear, logical presentation using tables and/or graphs as necessary.  Do not try to interpret at this stage.


Gives a summary of the main results and interprets them in relation to the theoretical background discussed in your introduction; relates your findings to professional practice by exploring the significance and implications; includes any limitations of the investigation and their significance.


Summarises briefly the main points of the discussion


Lists the references you have used by citation (when you identified where the information came from) to indicate your sources of evidence. You must use the Faculty’s preferred citation system, the Harvard system: see the Guidelines on Referencing in appendix 5 of the Undergraduate Modular Programme Handbook (page 73)


Includes any additional, supporting information that you may wish to include. You must refer to the appendix from within the main report.

Word Count

This does not include titles, tables/charts, references or appendices. Your total word count must be between 1800 and 2200 words, otherwise penalties will be applied.


Marking criteria

This assignment will be marked primarily on the descriptors of knowledge, analysis and application.

You should also demonstrate transferable skills of communication, use of learning resources/management of information and use of information technology.

See Appendix 10 Marking grids Level 1 in the Student Handbook.
