Abstract
Interventional radiology and cardiology can be associated with a significant radiation hazard to staff. A risk assessment developed for each facility can be used to assess the radiation produced and to define the steps required to minimise the radiation exposure of staff. A hierarchy of control measures should be implemented, including the consideration of environmental and equipment features, working practices and personal protection. Monitoring, particularly relating to radiation exposure at different locations, is essential to ensure the adequacy of safety measures. Co-operation between radiation safety experts and clinical colleagues to define and maintain radiation safety conditions will enable appropriate protection of specialist staff.
