[TheForge] Hellooooooo!

[Bruce Freeman]

But that wasn't medical WASTE.  

That same sort of thing happened in Brazil, when some moron scrapped
out a cobalt X-ray unit.  Scrap dealer broke it open and children
painted themselves with the cobalt because it glowed so pretty!!!  (No
joke.  Happened in the 80's I think.)  Needless to say, several people
died.

But that still wasn't medical WASTE.  That was a scrapped unit that
should have been recycled through some radiation authority, but wasn't.

Funny,
     When I was going through Nuclear Power training, and we were going
over nuclear accidents in America; The Thresher incident, The Army's
failed Nuclear program, etc., we were told that the worst nuclear
accident in North America was from medical not reactor nuclear
substances.  It involved a texas hospital, a mexican hospital, an X-ray
machine with a cobalt-60 source and a storage unit, thieves, a scrap
metal recycler, rebar, desks and some sensitive equipment and white
sands.

It is I who formed the blacksmith, 
who fans the flame into a fire and
fashions a weapon fit for it's work.
