Ion Chamber Calibration

[Larry_R_Sanders_at_~BMI4@battelle.org]

     I am posting this to RADSAFE for an individual who does not have 
     access.
      
     We are looking for a Sr-90 source jig to calibrate and response test  
     RO-20 or equivalent ion chambers. The source must be strong enough to 
     test all scales. If anyone has one, we would be interested in 
     purchasing it at a reasonable price. Please indicate so by responding 
     to my E-Mail address and not to RADSAFE.
