| Abstract: |
A nuclear battery in which the energy imparted to radioactive decay products during the spontaneous disintegrations of radioactive material is utilized to sustain and amplify the oscillations in a high-Q LC tank circuit is provided. The circuit inductance comprises a coil wound on a core composed of radioactive nuclides connected in series with the primary winding of a power transformer. The core is fabricated from a mixture of three radioactive materials which decay primarily by alpha emission and provides a greater flux of radioactive decay products than the equivalent amount of a single radioactive nuclide.

I claim:
1. Apparatus for converting radioactive energy to electrical energy, said apparatus comprising:
- an electrical conductor wound on a core to form an inductor having a first inductance, said core being of radioactive material;
- a capacitor having a predetermined capacitance C;
- a transformer having a primary winding, a secondary winding and a transformer core, said primary winding and said secondary winding wound on said transformer core, said primary winding having a second inductance, said secondary winding for coupling electrical energy to a workload; and
- electrical conductor means for connecting said inductor, said capacitor and said primary winding in series fashion to form a series LCR circuit wherein electrical oscillations are induced, said electrical oscillations being sustained and amplified by the energy transferred to said electrical conductor by the radioactive decay of said radioactive material, wherein L is the sum of said first inductance and said second inductance and R is a predetermined resistance.
