22、 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 cant 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
23、us but we cant detect them, sense them, without a radio receiver. Similarly, we cant 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
24、being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, an
25、d if they are killed immediately. 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 can grow into cancer. Sometimes this does not show up for many years. This is another reason for some of the
26、 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（辐射）and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorb
