This paper examines whether it can be achieved through the installation and use of an automatic filling station in a reduction of the PET hand dose of employees. The aim of this work is accomplished by comparing the dose evaluations of radiographers in the PET. Specifically, the dose in each ten months before and after installation and use of the AAS was used for the evaluation. The data is statistically analyzed and interpreted. It shows that by the use of AAS a significant reduction of the dose has been reached. By some refinements to the methodology there can be carried out meaningful studies in the future.
