The suitcase bombs the Soviets developed were actually quite sophisticated in this regard since they were rendered unworkable within six months if not maintained by an expert.

Yes DJ, but when there's a lot of the stuff close together, that half life must reduce a lot. The critical mass has to be close enough that neutrons from one must be wearing down the adjacent mass quicker than if there was just a pinhead of the stuff.

Isn't half life a function of incoming neutrons too? A single uranium atom wondering when to go pop, like Shrodinger's Cat in a box, would be more likely to go pop if a neutron came zinging through the box and got it in the head!
