I suppose that in least in theory there could be a DC-DC converter
circuit to convert that 1 megavolt low current into 9V, usable current,
rather than wasting the energy in a resistor.

I remember playing around with that idea of a nuclear battery as a
teenager. 3 parallel metal plates in a vacuum, the outer two connected
together as the (-) terminal, the middle plate had a thin layer of a beta
emitter on both sides and was the (+) terminal.  Output, maybe a million
volts at nearly zero current as betas went from the middle plate to the
outer plates..  The outer plates doubled as a radiation shield, too.
