Unit description
This unit is conducted to develop students' knowledge in the underlying physical principles of medical radiation science. The unit is presented in three distinct modules:
- Module 1 is the study of Radiation Physics, its principles and current technology of imaging equipment.
- Module 2 is the study of the principles and practice of image production and image processing techniques.
- Module 3 describes the biological effects of radiation as well as current radiation protection techniques.

General Assessment Information
LABORATORIES
You will be scheduled to attend 3 laboratory sessions throughout the semester. Missed session must be made up prior to week 13. A timetable will be released early in the semester to inform you which laboratory sessions you should attend. Please email the lab manager, Adam Joyce adam.joyce@mq.edu.au if you have concerns regarding your laboratory session time or to arrange making-up missed sessions.
IN-CLASS EXAMS
If an in-class exam is missed a supplementary exam will only be considered under the Special Consideration policy (https://students.mq.edu.au/study/my-study-program/special-consideration), applied for through www.ask.mq.edu.au within 5 days of the assessment.
Attendance at an in-class exam declares that you are fit to sit the exam. Re-sitting of in-class exams will only be considered under the Special Consideration policy (https://students.mq.edu.au/study/my-study-program/special-consideration), applied for through www.ask.mq.edu.au within 5 days of the assessment. If a re-sit occurs, either a VIVA (oral) or written format may be used.
THEORY EXAMINATIONS
The University Examination period for Semester 1, 2019 is from June 11th to June 28th 2019.
You are expected to present yourself for examination at the time and place designated in the University Examination Timetable. The timetable will be available in Draft form approximately eight weeks before the commencement of the examinations and in Final form approximately four weeks before the commencement of the examinations.
You are advised that it is Macquarie University policy not to set early examinations for individuals or groups of students. You are expected to ensure that you are available until the end of the teaching semester that is the final day of the official examination period.
The only exception to not sitting an examination at the designated time is because of documented illness or unavoidable disruption. In these circumstances you may wish to consider applying for Special Consideration. Information about unavoidable disruption and the Special Consideration process is available at https://students.mq.edu.au/study/my-study-program/special-consideration, applied for through www.ask.mq.edu.au within 5 days of the disruption
If you receive special consideration for the final exam, a supplementary exam will be scheduled in the interval between the 15th to 26th July. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. You can check the supplementary exam information page on FSE101 in iLearn (bit.ly/FSESupp) for dates, and approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination. If you are approved for Special Consideration and granted a supplementary exam, only your supplementary exam result will be counted towards your final grade.
If you attend and complete an examination you are declaring that you are fit to sit that assessment and Special Consideration will not normally be granted.
Students with a pre-existing disability/health condition or prolonged adverse circumstances may be eligible for ongoing assistance and support. Such support is governed by other policies and may be sought and coordinated through Campus Wellbeing and Support Services.
