摘要

报道了国际上有关放射性同位素电池研究的最新动态。首次提出了利用β粒子的电磁辐射实现由核衰变能向电能直接转换的基本设想，并制定了具体的与β伏特效应相结合的技术路线。以期在实验上获得空前的能量转化率，在核衰变能发电机制研究领域取得突破性进展，同时为核废物的再利用探索新途径。研究结果表明对９０Ｓｒ－９０Ｙβ源理论上可达到６２％的能量转换率极限，实验能量转换率可望达到２７％。

Abstract

A new principle is outlined for generating electrical power by ultilizing decay energy of the waste radioisotopes. The electromagnetic radiation emitted by βparticles in a magnetic field can be used in the energy conversion process. If this principle is combined with the beta voltaic effect

the theoretical energy conversion efficiency limit would be 62% for using 90Sr-90Y β source. The practical efficiency would be on the order of 27%. The preliminary experimental results showed that the efficiency of the beta voltaic process might be more than 14.2%.
