Cobalt

Hello,
from reading in the threads relating to nuclear war in the '80s, they
mention "cobalt weapons". Can anyone explain what these are? I very vaguely
remember a mention to them a book once but have no real idea.

The theory is that if you put a cobalt sheath around a nuclear
weapon you get lots of rather nasy cobalt 60 in the
fallout zone. The doomsday merchants would have you believe this
could wipe out all life on earth. The reality is nasty to be sure
but not quite that bad.

thanks Keith. I take it Co-60 is particularly nasty. I didn't know if the
whole idea of Cobalt bombs was enhanced blast, radiation, etc.
Were Co-60 weapons developed / deployed?

Cheers

Cobalt bombs were to be extremely DIRTY enhanced-fallout bombs,Cobalt-60
being a hi-level radioactivity isotope. I don't know what the half-life is
for it,though. Reasonably long,I suppose.

It's used for food irradiation sources in the US.

And the original "cobalt bomb" was a cancer radiotherapy device.

A little over five years, which makes for a very nasty fallout pattern.

The thing is, you would have needed a *lot* of cobalt bombs to kill (or
even seriously harm) all life on Earth. Outside of prompt fallout
patterns, you wouldn't see a lot of cobalt-60 contamination (the jacket
of cobalt would have been pretty inefficient at making the -60 isotope).

Basically, every Soviet warhead would have had to have been coated with
a hundred pounds or so of cobalt, and that was never going to happen.

You couldn't get a single bomb to vaporize enough cobalt, either, even
in the 100 megaton range.

Due to the way weather patterns work, the southern hemisphere would have
been mostly spared, too - you don't get a lot of mixing between north
and south.

According to
http://www.epa.gov/superfund/resourc...pdf/cobalt.pdf, 5.2 years.

cobalt/iodine weapon on the contents of Fort Knox, KY.

Enhanced fallout, mainly.

Co60 is a gamma and beta emitter, with a half-life of about 5 years;
pretty hot, and if ingested will dump most of its load during the
ingestees normal life, assuming a sublethal dose.

It's used for some medical applications.
