Stand-alone power supply energized by decay of radioactive iostope

摘要: A stand-alone low-voltage direct current power supply, for use as a battery, which is energized by the decay of radioactive isotope in response to neutron capture. During this decay, either α- or β-particles are emitted. The emitting should have adequate half-life and no γ-emission. preferred β-emitting radioisotope thallium, decays directly ground state Pb204 763-keV β-decay with resulting collected form can be used various purposes inside reactor. α-emitting americium.
