Is there a way to convert radiation from atomic decay into energy directly, the same way we do sunlight with a solar cell?

Couldn't we have a lead box lined with these radiation to electricity converters with a small amount of radioactive material in the center, and have an energy generating device that would last for thousands or even millions of years? Imagine putting the sun in a box lined with solar cells, but on a much smaller scale.

Is there a reason this wouldn't work?

RTGs aren't radioactive-specific, they are just a solid state way of turning a temperature difference into electricity. The better way to do this (at scale) is e.g. a steam engine, which is what big power plants do.

Wow! I think is a subject that I’d going to occupy my downtime for awhile. Thanks for the in depth info, also relevant username?
