摘要
Abstract
The radioisotope nuclear power source is a device that converts the energy released by the decay of radioactive isotopes into electrical energy.The development and present status of radioactive isotope source and the energy conversion device were reviewed.The radioisotope sources that can be selected for use include plutonium-238,strontium-90,americium-241,nickel-63,and tritium were pre-sented.The energy conversion technologies and energy conversion devices were expatiated according to the way of energy conversion.The use of suitable radioactive isotopes to prepare the power source has advantages that are unmatched by conventional power sources,such as a long service life,no con-straints from external environments,and no maintenance.As a self-sustaining power source,radioiso-tope nuclear power sources have an indispensable role in harsh environments such as no light,weak light,low temperature.The present situation of radioisotope nuclear power source was introduced in the military and medical applications.The direction of technology development and the application prospects of product were envisioned.关键词
