Unit Overview


This unit provides an understanding of the effects of ionising and non-ionising radiation on the human body and the risks involved in the use of radiation and radiation protection methods. It introduces the student to the basic concepts and principles of radiation safety including an understanding of the underlying physics, the biological effects of radiation, sources of radiation, risk identification, exposure and protection methods. An understanding of the national and state legislative requirements with respect to various forms of radiation is also developed.

Students are able to (1) understand basic concepts of radiation physics including the properties of ionising and non-ionising radiation; (2) discuss biological and health effects of radiation; (3) use appropriate units to quantify radiation exposure; (4) discuss sources of natural and artificial radiation; (5) describe the principles underlying risk reduction and procedures to minimise risk of exposure; (6) discuss legislation regarding protection and safety; (7) perform basic procedures that involve use and monitoring of radiation; and (8) describe approaches for monitoring of staff and work areas.


Indicative assessments in this unit are as follows: (1) tutorials (5 per cent); (2) assignments (30 per cent); (3) safety courses (20 per cent); and (4) a three-hour, end-of-semester examination (45 per cent). Further information is available in the unit outline.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
  • Contact hours provide an indication of the type and extent of in-class activities this unit may contain. The total amount of student work (including contact hours, assessment time, and self-study) will approximate 150 hours per 6 credit points.
