Since an electric current is nothing but a flow of electrons, it has been obvious for years that a "beta emitter" might serve as the source of energy in a battery. How to build such a battery was not so obvious. If the electrons are merely collected like spent shot from a shotgun, most of their energy is lost...
Last week Radio Corp. of America demonstrated a sub-thimble-size radioactive battery that is somewhat more efficient. A film of Strontium 90 is spread on a wafer of silicon.
