参考解析
解析：第一段就明确指出核能的危险在于它的核辐射。
第三段提到即使很微量的辐射也会带来严重的后果，主要因为受损伤的细胞会以畸形的方式自我复制，进而转变为癌症。
significant此处指“要紧的，致命的”所以选A。
略
文章第二段和第四段分别提到了不同的reasons for some of the mystery about nuclear radiation，由此可以推断，核辐射仍然是一个未解之谜。

共用题干第二篇Nuclear Power and Its DangerNuclear 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. It 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 invital organs.But even the lowest level of radiation can do serious damage.There is no level of radiation that is comnpletely 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 outright.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.
