Re: I-129 Sources

[Robert A Scott <bobscottchp@juno.com>]

	The simplest way to get a check source is to make it yourself.  Find
some uranyl nitrate.  Most places have an old bottle of the stuff stuck
way back in a corner of the cabinet.  Mix some with some liquid epoxy
resin, and flatten it out in a zip lock plastic baggie.  After it
hardens, cut it up into small (5 mm X 10 mm) strips.  Attach it to the
lip of the survey meter using some more clear epoxy resin.  (Make sure
the paint or smooth surface of the meter lip is scratched deeply enough
to allow the hardened resin to "grab" for a long time).  After drying,
determine the reading on the meter, and record it on the calibration
label.  Now you have a check source that will last longer than the meter.
