11 (a) (i) "Read the following passage and answer thequestions given at the end: Space is a dangerous place, not onlybecause of meteors but also because of rays from the sun and theother stars. The atmosphere again acts as our protective blanket onearth. Light gets through, and this is essential for plants to makethe food we eat. Heat, too, makes our environment tolerable and someultraviolet rays penetrate the atmosphere. Cosmic rays of variouskinds come through the air from outer space, but enormous quantitiesof radiation from the sun are screened off. As soon as men leave theatmosphere they are exposed to this radiation but their spacesuits orthe walls of their spacecraft, if they are inside, do prevent a lotof radiation damage.Radiation is the greatest known danger toexplorers in space. Doses of radiation are measured in units called'reins'. We all receive radiation here on Earth from the sun, fromcosmic rays and from radioactive minerals. The `normal' dose ofradiation that we receive each year is about 100 millilitres (0.1 rem);it varies according to where you live, and this is a very roughestimate. Scientists have reason to think that a man can put up withfar more radiation than, this without being damaged; the figure of 60rems has been agreed. The trouble is that it is extremely difficultto be sure about radiation damage. A person may feel perfectly well,but the cells of his or her sex organs may be damaged, and this willnot be discovered until the birth of (deformed) children or evengrandchildren.Early space probes showed that radiation variesin different parts of space around the Earth. It also varies in timebecause, when great spurts of gas shoot out of the sun (solarflares), they are accompanied by a lot of extra radiation. Someestimates of the amount of radiation in space, based on variousmeasurements and calculations, are as low as 10 rems per year, othersare as high as 5 rems per hour, Missions to the moon (the Apolloflights) have had to cross the Van Allen belts of high radiation and,during the outward and return journeys, the 'Apollo 8' crewaccumulated a total dose of about 200 millilitres per man. It was hopedthat there would not be any large solar flares during the times ofApollo moon walks because the walls of the LEMS (lunar excursionmodules) were not thick enough to protect the men inside, though thecommand modules did give reasonable protection. So far, no dangerousdoses of radiation have been reported, but the Gemini orbits and the'Apollo 8' missions have been quite short. We simply do not know yethow men are going to get on when they spend weeks and months outsidethe protection of the atmosphere, working in a space laboratory or inbase on the moon. Drugs might help to decrease the damage done byradiation, but no really effective ones have been found so far. Atpresent, radiation seems to be the greatest physical hazard to spacetravellers, but it is impossible to say just how serious the hazardwill turn out to be in the future. "
