>>12775147Nuclear orbitals bruh, nuclei are tiny and so the wavelength of the radiation they emit is tiny, that makes it spicy to your bones.
I guess if you wanted your comfy rock chair to sun on like the lizard that you are deep in your soul you could always go down the RTG path and get an alpha only emitter with some assembly to regulate the heat & vent the helium. Biggest problem is most of the isotopes with a power output that you'd want are produced in a neutron generators so you're going to have to compete against NASA and hospitals and pay their prices or build one yourself, and risk having 8 different flavours of fed from 3 different countries smash through your window and shoot your dog if you fuck your paperwork up.
