Re: Lantern mantles

[Mike Dupray <dupray@gat.com>]

I beleive you are all making a mistake. Use of lantern mantles is only good
for demo's and shows. You cannot properly performance test an instrument
with an uncalibrated source. You need to prove that the calibration of the
instrument is still good. The only way to do it right is to use a traceable
standard(s) and test each scale to mid scale. Anything else tells you
nothing except that the needle moves when exposed to radiation.
