[ RadSafe ] Curiosity query

[Joseph Shonka]

A useful unclassified description can be found at
http://en.wikipedia.org/wiki/Little_Boy

The material was HEU, (> 90% U-235) which was never irradiated in a reactor
and thus had lower external radiation fields than normal uranium.  Aside
from welding the transport case onto the deck of the USS Indianapolis,
there was no need for special handling.
