wsj.com/articles/study… Study: Deep-Space Radiation Could Damage Astronauts’ Brains
2015-05-05 17:20:34引用 : To test the neural effects of deep-space travel, a dozen researchers led by UC Irvine radiation oncologist Charles Limoli briefly
2015-05-05 17:20:48引用 :exposed mice to charged particles in a radiation beam at the U.S. Department of Energy ’ s Brookhaven National Laboratory in Upton, N.Y
2015-05-05 17:20:50引用 :Six weeks later, they tested the irradiated mice and found the lab animals lacked normal curiosity, were less active,

2015-05-05 17:20:58ガンマ線とかじゃなくて酸素とかチタンの高エネルギー粒子でエネルギー は 600MeV/amu と。普通の α 線より高いので、ある程度の飛程があるのかな?
2015-05-05 17:21:02実験に使った被曝量は 30cGy と 5cGy と。それくらいで色々なテストの 成績が有意にさがったということのようである。
