This work suggests a classification of interventional radiology and cardiology proceduresbased on statistical analysis of operators’ finger doses measured in routine clinicalconditions. In total, 346 finger doses were measured and the observed mean finger dose perclass of procedure ranged from 0.03 mSv to 1.56 mSv for Cerebral, and Bone and Jointprocedures, respectively. The statistical analysis showed that the finger dose in Cerebralprocedures is significantly lower than in Cardiac procedures, which was significantlylower than the rest. Furthermore, finger doses in therapeutic procedures and in close oneswere significantly greater than in diagnostic procedures and in distal ones. This workalso studied the statistical relation between the use of ceiling-suspended shields orleaded gloves and the extremity dose. From the set of collected and analyzed data, afinger dose classification was proposed for different criteria: procedure type(diagnostics/therapeutic), proximity (close/distal), procedure class and access route.
