<grin> Gee, I wonder *why* they were doing that? ;-) Reason was partly for obvious use in radiological
environments,
but it was also an attempt to speed up the time element I refered
to w/o having to let semiconductors lay around for years to see
affects.
Ah! I guess there *are* some "peaceful applications"! :>
the plastics, ceramics, and metals used in the
manufacture are
nowhere near as pure as the semiconductor materials used,
so they wanted to see what zapped what. gamma, xray, beta,
and alpha, and what did it do, and how fast.
