英语翻译
Space is a dangerous place,not only because of meteors but also because of rays from the sun the other stars.The atmosphere again acts as our protective blanket on earth.Light gets through,and this is essential for plants to make the food we eat.Heat,too,makes our environment endurable.Various kinds of rays come through the air from outer space,but enormous quantities of radiation from the sun are screened off.As soon as men leave the atmosphere they are exposed to this radiation,but their spacesuits or the walls of their spacecraft,if they are inside,also prevent a lot of radiation damage.
Radiation is the greatest known danger to explorers in space.The unit of radiation is called “rem”.Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on.The trouble is that it is extremely difficult to be sure about radiation damage.For example,a person may feel perfectly well,but the cells of his or her sex organs may be damaged,and this will not be discovered until the birth of deformed children or even grandchildren.Missions of the Apollo flights have had to cross belts of high radiation and,during the outward and return journeys,the Apollo crew accumulated a large amount of rems.So far,no dangerous amounts of radiation have been reported,but the Apollo missions have been quite short.We simply do not know yet how men are working in a space laboratory.Drugs might help to decrease the damage done by radiation,but no really effective ones have been found so far.

太空是一个危险的地方,不仅因为流星也是因为太阳的光线从其他恒星.气氛再次充当地球的防护毯.轻获得通过,这是使植物吃.热也一样,我们的环境承受能力.各种射线来通过空外太空 但大量的太阳辐射,放映过.男子尽快离开这个气氛,接触到他们辐射 但其宇航飞船或墙壁,如果他们心里 又可防止大量辐射伤害.已知的最大危险是辐射在太空探险.该股辐射现象称为"物".科学家有理由认为一个人可以忍受远远超过0.1辐射物不受破坏; 接下来的60个数字已经商定.麻烦的是,很难予以肯定的辐射损伤.例如,一个人可能觉得非常好,但他或她的性器官细胞可能损坏,这将不容易被发现,直到孩子出生畸形甚至孙辈.阿波罗飞行任务有高辐射和带过,在来回路程,积累了大量的船员阿波罗食盐.到目前为止,没有辐射危险金额已报告,但阿波罗任务也相当短.但我们根本不知道如何在太空实验室正男.药物可能有助于减少辐射的伤害,但一直没有找到真正有效的为止.
