ABSTRACT
A study was conducted to analyse performance of industrial radiography in incidents where worker errors resulted in radiation exposure to personnel. Results indicated that the most common errors involve diagnosis of system status, development of work strategies, and the proper execution of procedures. An information processing model was applied to characterize the errors. In further examination of the field radiography task, a theoretical framework for cognitive processing is proposed to explain risky behaviour, and to indicate how training could be designed to reduce errors. The premise for this approach is based on the notion that the manner in which information is obtained and stored in memory has a direct influence on how the information will be used.
