True of some warheads, not true of others.

Davy Crockett was an entirely mechanical system with no safeties other than what you would see on a conventional arty round.... and it was stored VERY near criticality.

It gave off so much heat that in Germany in the winter they were moved from bunker to bunker every few days because the hear would melt the snow off the bunker roof and thereby let the bad guys know where they were being stored!

If the Davy Crockett rounds were that close to criticality, what was the radiation situation?

Any crews sprout extra arms?
