Re: To Luxel Users

[Mike Lantz <mlantz33@cybertrails.com>]

Several commenters on this issue have noted that you can choose a higher value
than 1 mrem on the Luxel.  So guys!  Don't pick 10 mrem.  It is pretty
historically-based.  Specify 4, or 5, or 8 mrem.  Wherever your false positive
rate is low for your system of storage, transits through the mail, etc.

As a NVLAP Assessor for years, that would always be of interest to me  --  where
the minimum reportable was set and how it was determined.  Quit picking 10 out of
history.  Landauer has jumped out there and said 1 mrem is resolvable.  To me, in
my opinion, the false positive rate may be too high at some facilities.  That's
all I'm saying about it.

The minimum reportable at my NPP is much lower than 10 mrem per month or per
quarter.  And it is well documented and routinely evaluated with the capabilities
we have; e.g., a report of any positive TLD dose with no RCA entries and a report
of EPD total vs TLD total.  My previous note on this issue simply supported a
client's best effort at evaluating her false positive rate.
