空间重离子辐照效应评述

A review on space heavy ion irradiation effects

  • 摘要: 文章对生物、半导体、光学材料、金属、聚合物的空间重离子辐照效应的研究工作进行了评述,也阐明了深入开展重离子空间环境模型以及重离子辐照效应与演化规律的研究具有重要意义。研究表明空间环境中重离子的含量虽少,但由于其高的电离能力和穿透力,对生物、半导体、光学材料、金属、聚合物等会产生各种辐射损伤效应,导致卫星信号故障、光学器件失效、金属与聚合物性能及形貌改变,甚至影响航天员的生命安全。

     

    Abstract: This paper reviews the studies of space heavy ion irradiation effects on organisms, semiconductors, optical materials, metals, and polymers. The model of heavy ion space environment, the heavy ion irradiation effects and material performance evolution are important research issues. It is shown that the relative number of heavy ions in the space environment is small, but the radiation damage effects on organisms, semiconductors, optical materials, metals and polymers can not be ignored for the high ionization and penetration capacity of heavy ions, which would cause the signal malfunction of satellite, the fault of optics, the performance and morphology changes of metals and polymers, even would threaten the life safety of astronauts.
