Description
English: NASA Physicist studying Alpha Rays in a continuous cloud chamber. A cloud chamber is used by Lewis scientists to obtain information aimed at minimizing undesirable effects of radiation on nuclear-powered aircraft components. Here, alpha particles from a polonium source emit in a flower-like pattern at the cloud chamber's center. The particles are made visible by means of alcohol vapor diffusing from an area at room temperature to an area at minus -78 deg. Centigrade. Nuclear-powered aircraft were never developed and aircraft nuclear propulsion systems were canceled in the early 1960s.
日本語: 1957年、NACAの物理学者が霧箱でアルファ線を観察している所。核エネルギーを動力とする航空機の研究上の一環で、放射線がもたらす望ましくない影響を最小化するための研究の一部。中心に置かれたポロニウムから出される放射線(アルファ粒子)が、霧箱中で花びらのようなパターンを描いている。室温からマイナス78℃の空間に向けて噴射された気化したアルコールによって、アルファ粒子が目に見えるようになっている。原子力航空機の開発計画は1960年代に中止され、結局実現されることはなかった。
