HZEおよび宇宙放射線の遺伝的影響

—準備期間や飛行中に生じた種々の問題点—

抄録

The purpose of our study was to analyze possible induction of mutations caused by cosmic radiation in fruit flies, Drosophila melanogaster. This article describes various troubles which we had encountered during the course of preparation of flight samples and also during the flight. They were mainly due to the inconvenience of flight hardware such as defects in culture vials for Drosophila and malfunction of incubator. Some proposals will also be presented to avoid such troubles in the future space experiments.
