RE: mailing radioactive material
Title: RE: mailing radioactive material
This is
probably a moot point, as the subject was thorium nitrate. The USPS regs
are pretty restrictive about dangerous goods - basically, if it needs a label
(in the shipping sense) you can't send it.
Thorium
nitrate is both radioactive and an oxidizer. This is what Franz
Schoenhofer was referring to when he mentioned explosive characteristics - it
doesn't explode in itself, but it facilitates combustion/explosion of other
materials.
A number of
years ago, a field researcher sent me a radium dial compass as part of an
exposure investigation. He blithely sent it US Mail. In a
manila envelope. To send it back, I had to pack it in a jar of lead shot,
and overpack that in an 18 inch cubic box of Styrofoam 'peanuts'. That got
it under the surface dose rate limits - just.
