摘要
Provided is a fuel design configured to have a thickness that is equal to or less than a mean-free path of electrons emitted by a radioactive energy source to prevent electrons produced thereby from being stopped within the fuel design and thus preventing bremsstrahlung radiation from being generated within the fuel design. Additionally provided is a two-phase shielding system including a first shield formed of a first material having a thickness exceeding a mean- free path of an electron emitted from a radioactive source material so as to prevent the electron from passing through the first shield, and a second shield formed of a second material configured to prevent bremsstrahlung radiation generated by the electron from passing through the second shield.
