Instrument Calibration

[Phurst]

I am evaluating our current instrument program and am intrested in seeing calibration cycles from other sites and users.

Generally, 12 months is the accepted criteria.  However, some of my Final Status survey plans required our instruments be within 6 months of its calibration.

current site does dose rate & direct contamination instruments every 3 months, a/s @ 6 months, indirect contamination equipment anually.  these are site specs.  brings real meaning to the phrase.... a man gotta eat!

And how do you cal them? In house or do you send them out? To who?

While working for SEC, we rented SEC instruments from the SEC instrument shop (800 905 0501), they also did the calibrating of our instruments.

As far as anual calibrations vs others, anual is all that is required unless you commit to something else.
