[ RadSafe ] rad monitor calibration

[ROY HERREN]

The calibration procedures will vary depending on which specific instrument your calibrating.  Unless you have the in-house expertise, I highly suggest that you leave the instrument calibration to the instrument vendor.  In any case, your instrument vendor should have provided you with an instrument manual when you purchased each of the instruments.  Look through the instrument manual to see if it lists any information about instrument calibration.  Do you own an instrument calibration source?  If so, also look up what the literature from calibration source manufacturer/vendor provides regarding instrument calibration.

Thx for the info.
BTW - - nothing to do with global warming - - just a request for help 
'cause its not good to look stupid in front of management.  ;-)
my contribution to the global warming debate is mostly unsupported hot air 
anyway

We measured the field from our calibration source with a 1 L ion chamber
connected to a PTW electrometer.  This instrument had been calibrated by a
secondary standard laboratory and their source (or instrument) was 
compared
to the national standard maintained by NIST in the U.S.  You may want to
consult ANSI Standard N323A-1997 or the ISO equivalent.  But, what does 
this
have to do with global warming?

Can somebody point me to a good (readable)
 description of the rad monitor
calibration process.
What, I need is something that provides a description of how the process
proceeds, as in:

primary calibration => secondary calibration=> tertiary/transfer 
calibration

Basically our group performs radiation (source) transport,  sensitivity 
and
setpoint calculations, but we're just now being asked to answer questions
related to calibration.  I expect that they can/should be referred back to
the vendor, but still, we should have a reasonable understanding of what's
being asked. (We've got a fair amount of "water cooler" information, but
nothing truly complete.) Thx in advance  - - jmr
