1. A fuel design, comprising:
a radioactive source material comprising a high-energy beta emitter, wherein:
the fuel design is configured to have a thickness that is equal to or less than a mean-free path of electrons emitted by the radioactive source material such that an electron emitted by the radioactive source material as a result of a beta decay process is able to pass through the fuel design without being stopped so as to prevent bremsstrahlung radiation from being generated within the fuel design.
