MEDI12001 Radiation Science
Radiation Science
All details in this unit profile for MEDI12001 have been officially approved by CQUniversity and represent a learning partnership between the University and you (our student).
The information will not be changed unless absolutely necessary and any change will be clearly indicated by an approved correction included in the profile.
General Information


This unit prepares you for the safe and effective use of ionising radiation for radiographic imaging in the simulated and clinical environment. The unit covers production and control of the radiation beam, radiation interactions in matter and risk of detriment to the human body from exposure to radiation. Radiation safety and dose minimisation practices are examined in light of current findings on detriment from low level radiation.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability. See details in the Assessment Policy and Procedure (Higher Education Coursework).

Offerings For Term 1 - 2022


Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Class and Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Class Timetable

Assessment Grading

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%). Consult the University’s Grades and Results Policy for more details of interim results and final grades.

Previous Student Feedback

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Feedback from Unit coordinator self-reflection


Students appreciated the adaptation of multiple small groups during the tutorials to support their engagement and learning in the unit.


Continue utilising the multiple small group approach in the tutorials so that the students have the opportunity to engage, participate, discuss and answer the tutorial questions with other group members.

Feedback from Have your say Unit coordinator reflection


Students found the weekly tutorials supported them in reviewing and consolidating the concepts covered in the unit.


Continue with the weekly tutorials to support student learning.

Feedback from Have your say


There is an expectation among some students that they can study the unit by reading through the lecture slides only and not watching the pre-recorded lecture videos.


Emphasise the importance of watching the lecture video in conjunction with the lecture slides in the future iteration of the unit.

Feedback from Have your say Unit coordinator reflection


Some students found the first four weeks of the unit, which was physics-content heavy, challenging and they struggled with these topics in their first assessment held in Week 5.


Investigate the option of having the first assessment in Week 6 instead of Week 5 to give students more time to engage with the content and complete the review and consolidation of the topics in preparation for their assessment.

Unit Learning Outcomes
On successful completion of this unit, you will be able to:
  1. Discuss the design, structure and operation of the x-ray tube in the production of x-radiation
  2. Discuss the use of technical parameters, filters and collimation to control the useful x-ray beam's contents and dimensions
  3. Apply underlying physical concepts in discussing the processes of x-ray photon production, x-ray interactions with matter and differential attenuation, in explaining the factors that affect each and in explaining the various metrics of radiation quantity and risk
  4. Discuss current scientific understanding of the bioeffects and associated risks of radiation at the levels used in diagnostic radiology to body cells, tissues and systems across the lifespan
  5. Discuss radiation safety regulations, legislation and associated best practice standards as they apply to occupational exposure and safe use of ionising radiation in diagnostic imaging.

This unit links to the following Professional Capabilities for Medical Radiation Practitioners as detailed by the Medical Radiation Practice Board of Australia (effective 1 March 2020):

  • Domain 1A:1 Perform projection radiography examinations in a range of settings (parts a,d)
  • Domain 5:1 Perform and provide safe radiation practice (parts a,b,c,d,f)
  • Domain 5:4 Maintain safety of the workplace and associated environments (a,c,d,e,f,g)
