Abstract
The present invention is directed to an encapsulated β− particle emitter that comprises a sol-gel derived core that comprises a β−-emitting radioisotope and an encapsulant enclosing the core through which at least some of the β− emissions from the β−-emitting radioisotope pass, wherein the encapsulant comprises a substrate and a cover and at least a portion of the encapsulant is electrically conductive, and a method for making the same. Additionally, the present invention is directed to a capacitor comprising such an encapsulated β− particle emitter and a method of performing work with such a capacitor.
