Information on Free Air Calibrator

[barberj@m4lp.com (Jerry Barber)]

     Hello Radsafe,
     
     I am looking for information on a Radiac Calibrator Set (Free Air 
     Collimated Calibrator) Model AN/UDM-1A.  I would like to converse with 
     someone who is currently using this device.
     
     Alternatively, I understand that this device is used at the University 
     of Rhode Island.  Could anyone provide me with a contact?
     
     Thanks
