ABSTRACT
The objective of radiation protection is to protect people and the environment against the harmful effects of ionizing radiation. In order to achieve this objective it is necessary to estimate the chance that something could go wrong, evaluate the consequences that would result and install sufficient control and protection systems to ensure that these consequences are acceptably low. This is achieved through a process called risk assessment, which involves:
⦁ identifying the hazard;
⦁ estimating the size of the risk; and
⦁ assessing its importance in comparison with other risks.
