Re[2]: Instrument Calibrations

["Eric L. Darois" <daroiel@naesco.com>]

     Pulsing has been "approved" on a case by case basis when reasonable by 
     both the NRC and instrument manufacturers.  For example, contamination 
     monitors, low range survey meters (micro-R, micro-rem...), and 
     rem-balls.  My experience is that tha NRC will not "require" licensees 
     to purchase an unreasonable arsenal of sources for calibrations.  The 
     main point is to demonstrate that the electronics and detector 
     function well at the time of calibration.  There a some choices which 
     are "allowed".

Sorry I just getting involved in radsafe very recent so I may have 
missed some correspondance.  But anyway,  the NRC does not accept 
Pulsing as a technique to calibrate survey instruments.  They must be 
calibrated by using a point source and must have at least 2 points per 
scale.  You may elect to pulse the meter first to get you close, but 
then it must be calibrated using NRC approved cal. technique.
     
I'd be happy to help either giving you a technique or protocol or even 
calibrating them for you.  Just write back.
     
Good Luck
