In the limit, packing transistors tighter should mean more radiation resistance, not less, because you can shield them with a smaller mass of water or lead or whatever.

It would be funny if lead-acid batteries end up being space-grade, should the lead be able to serve as a radiation shield.

		IIRC, metals aren’t great shields because of secondary particles emitted after the first one hits the shield.
