摘要
随着航天员在太空停留的时间逐渐延长 ,各种航天环境因素对航天员的影响更加显著 ,紫外线缺乏也成为一个重要因素。研究表明 ,低剂量 ( 1 0mJ/cm2 )的紫外线照射对人体是有益的而且是必需的 ,它可增强机体免疫功能 ;改善载人航天时周围环境的卫生条件 ,提高机体的工作能力和航天中不利因素的抵抗力 ,预防航天员飞行中矿物质丢失 ,治疗皮肤化脓性疾病和变态反应性疾病 ;对变态源的脱敏等。所以 ,对长期航天时的航天员适当进行紫外线照射是十分必要的。
With the prolongation of space flight,influences of various aerospace environmental factors on the astronauts become more and more severe,while ultraviolet radiation is lacking.Some studies indicated that low doses of ultraviolet rays are useful and essential for human body.In space flight,ultraviolet rays can improve the hygienic condition in the space cabin,enhance astronaut's working ability and resistance to unfavorable factors,prevent mineral metabolic disorders,cure purulent skin diseases and deallergize the allergens.So in long term space flight,moderate amount of ultraviolet rays in the space cabin would be beneficial.
