I'm not too sure about this, I once read a story about using an
anti-nutronium bomb to turn the Earth into another asteriod belt. 

Forgive my ignorance - but I don't remember Neutronium as one of the 
elementary particles.  And if it is a compound on the periodical 
table, it certainly does not have an "anti-" anything to 
atomically react with.

I was under the impression that neutronium is made up of neutron
in a very compressed state, usually formed only under the most
extreme conditions (such as a collapsing heavy star).

As anti-matter is protons/electrons with a reversed electrical charge, 
and neutrons by definition have no such charge, I don't know if
anti-neutrons are not a contradion in terms.

It's different if its sub-atomic, though. Anyone with a recent physics
class on line ?
