RAD1072 - Radiologic dosimetry and safety

Leader: Dr Ray Budd

Offered

Clayton Second semester 2007 (Day)

Synopsis

Ionising radiation, x-radiation and its effects on living tissue. The energy content of an x-ray beam. Dose and equivalent dose calculations. Units and standards in dose and equivalent dose measurements. Radiation risk and protection. Occupational exposure and patient exposure. Personal dosimetry, film, TLD and pocket ionisation chambers. Integral dose and dose-area products. Equipment used for radiation monitoring. The statutory requirements for the safe practice in the use of ionising radiation.

Objectives

On successful completion of this unit students will be able to calculate:

1. the energy content of an x-ray beam;
2. the dose and equivalent dose when x-rays are absorbed by living tissue, using correct units; and
3. the integral dose and dose-area product.

On successful completion of this unit students will understand:

1. the response of organ systems to ionising radiation exposure;
2. the need for safety in the radiation areas - both at a personal and patient level; and
3. the ways x-radiation is monitored and measured and how personal monitoring is used, recorded and reported.

On successful completion of this unit students will be able to:

1. describe the manner in which ionising radiation may be measured and reduced;
2. describe how the regulatory agencies require ionising radiation equipment to be used in a safe manner; and
3. demonstrate a detailed knowledge of the statutory regulations governing the use of ionising radiation.
