[Place of the radiation safety officer in the implementation of the ALARA principle through European directive 97-43 items].

The purpose of this article is to define the role of the radiation safety officer in raising the awareness of the radiology staff to the ALARA (As low as reasonable achievable) principle specified in European directive 97-43. The actions taken and the techniques used in our hospital, as well as the potential improvements that could be achieved with extra funding, will be presented. The didactic value of flow charts recording technical factors and fluoroscopy times for quality improvement will be demonstrated. In the future, a dosimeter incorporated on the new equipment could allow direct recording of the dose. The different items presented in this paper should allow routine implementation of the required elements described in the law 2003-270, i.e the French translation of European Directive 97-43.
