     This is my opinion.  If there is a hole in any lead apron, the apron 
     is replaced.  Understanding that 0.1mm would not increase the dose 
     received by the individual wearing the apron...It is the preception 
     that the apron has loss its intergity and will continue to do so in 
     time.  When we noted loss of shielding in lead aprons, the aprons were 
     replaced..mike coogen

Lead aprons used in Radiology are inspected annually. What are the 
recommendations for action if a hole is found in the apron when inspected 
under fluoroscopy? (this hole is less than 0.1 mm in diameter).
     
If one says that the hole is so small as to be of negligible effect, then how 
large must a hole be to warrant action?
     
Thanks for your help,
