Nuclear Power and Its Danger
Nuclear power's danger to health,safety,and even life itself can be summed up in one word:radiation.
Nuclear radiation has a certain mystery about it,partly because it cannot be detected by human senses.
lt can't be seen or heard,or touched,or tasted,even though it may be all around us.There are other things like that.For example,radio waves are all around us but we can't detect them,sense them,without a radio receiver.Similarly,we can't sense radioactivity without a radiation detector.But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels,radiation can kill an animal or human being outright by killing masses of cells in vital organs.But even the lowest level of radiation can do serious damage.There is no level of radiation that is completely safe.If the radiation does not hit anything important,the damage may not be significant．This is the case when only a few cells are hit,and if they are killed outnght.Your body will replace the dead cells with healthy ones.But if the few cells are only damaged,and if they reproduce themselves,you may be in trouble.They reproduce themselves in a deformed way.They can grow into cancer.Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation.Serious damage can be done without the victim being aware at the time that damage has occurred.A person can be irradiated and feel fine,then die of cancer five,ten,or twenty years later as a result.Or a child can be born weak or liable to serious illness as a result of radiation absorbed by its grandparents.
Radiation can hurt us.We must know the truth.Radiation1 can cause serious consequences even at the lowest level______.
A:when it kills few cells
B:if it damages few cells
C:though the damaged cells can repair themselves
D:unless the damaged cells can reproduce themselves答案：B解析：由文章第一段“Nuclear power ' s danger to health , safety , and even life itself can be summed up in one word : radiation.”可知，核能对人类健康、安全甚至生命造成的威胁可归纳为一个词：核辐射。故选C。
由文章第三段第二句话可知，即使是强度最低的核辐射也会造成严重伤害。接下来作者对此从两方面进行说明，其中第二方面，即第七、八、九句话说，如果细胞仅仅是被破坏了，它们可能会再生，发展为畸形，并最终生成癌细胞，对人体造成危害。故选B。
由文章第三段第四句话“If the radiation does not hit anything important , the damage may not be significant.”可知，如果核辐射没有破坏重要的细胞，这种伤害可能不是致命的。significant意为“致命的”，与fatal（致命的）意思相近。故选A。
由文章第三段第一句话可知，选项A（杀死主要器官里的大量细胞，导致人或动物立刻死亡）是正确的。由文章第三段最后两句话可知，选项B（损伤细胞，致使细胞多年以后发生癌变）是正确的。由文章最后一段最后一句话可知，选项C(影响我们后代的健康）是正确的。故选D。
题干的意思是能从文章中推断出的最恰当的陈述是：A．预防核辐射的重要性再强调也不过分；B．辐射的秘密还没有揭开；C．癌症主要是由辐射引起的；D．辐射可能伤害那些意识不到辐射危害的人。文章通篇都在讲核辐射的危害以及可能导致的严重后果，由此可推断出A项正确。故选A。 -
