NA-24 Tracer Testing

["werner k paulhardt" <werner_k_paulhardt@bge.com>]

     Hello,
     
     I'm interested in input from anyone with experience in NA-24 and 
     Lithium Tracer Testing of Main Steam Systems in Nuclear Power Plants.
     
     1. Advantages/Disadvantages of NA-24?  Same for Lithium?
     
     2. If you were using NA-24 and switched to Lithium, what were the           
        justifications?  Same for Lithium to NA-24 change?
     
     3. Any dose received to individuals due to mishandling of source or due to  
        the test in general?
     
     Please send responses to werner_k_paulhardt@bge.com or call (410)260-4773.
     
     Thanks in advance.
