Lawrence --

The sources themselves did survive the
fire intact ... oh, and if you want fun, try
shipping several of the source rods
without the lead to shield them. Yep ... it
was fun alright, but I wouldn't want to do it
again!

Re Moisture Density Gauges and Al
Tesche's questions:

All M-D gauges have A2 class sealed
sources, therefore are tested to meet
the DOT requirements for an A2 sealed
source: drop test, fire, moisture,
etc.  The shielding may melt in a fire, but
the source should always remain
intact (extracting the source from the
melted shield is a lot of fun - if
you are a masochist).

The gauge itself is never used as the
transport container.  All have an
external case in which the gauge is
carried.  The case is typically designed
to the exempt limited quantity
specifications or the Type A container
specification (presuming it is a newer
model - some of the old M-D cases
have wooden box construction that does
not meet today's regulations.)

Other than the neutron dose
considerations, the recovery of a
damaged M-D
gauge should be a piece of cake and not
a major media event.
