The device I was thinking of was a medical radiation generator for
the treatment of cancer.  However, a reference that Ken Garlington
gave earlier on c.l.a. led me (eventually) to a report on the 
Therac-25 which I believe is the machine that made it into urban
legend as the killing machine.  I have not completed reading the 
report yet, but I also have not discovered any incidents of morbidity
directly attributable to the massive radiation overdoses that some
patients were exposed to.  A Google search on "therac 25" pops up
about 1050 links.
