[Test-Equipment] Radioactive Tube Stamp

[Mike Manes]

Bob's right - and I was mistaken.  Th is an alpha emitter (He4 nucleus
that's too large and heavy to penetrate even a sheet of paper).

See: http://en.wikipedia.org/wiki/Thorium_series#Thorium_series

Coulda sworn I used Coleman mantles to check a G-M tube with a metal shield,
tho.  Must be suffering CRS.
