Nuclear radiation（核辐射）has a certain mystery, partly because it cannot be detected（探测） 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 but we can’t detect them or 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 important organs. Even the lowest levels 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 serious. This is the case when only a few cells are hit, and when 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 an unusual 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 knowledge of the person at the time that damage has occurred. A person can be irradiated（放射治疗）and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.According to the passage, the danger of nuclear power lies in __________.

Diao Weihao, a student who studies business English at the Chengdu campus of Sichuan International Studies University, was in his dormitory when the earthquake struck at 2:30 pm on Monday.
The 22-year-old felt that his chair was shaking. All of a sudden, the textbooks on the bookshelf began to fall to the floor. The glass in the window broke.
“It felt like our dormitory building was being hit by a tractor,” recalled Diao. “I wasn’t afraid.. I was even excited and curious. Now, looking back, it was a scary experience.”
Diao and his roommates kept their calm. They didn’t try to get out of the building until the shaking stopped. They were on the fifth floor and they feared there might be trouble if they didn’t remain calm.
“We’ve watched lots of disaster films, and that helped us keep cool,” he said. “Only one student sprained（扭伤） his ankle. He was escaping in a hurry. Most of us got outside quickly and safely.”
They were surprised to see so many students outside.
“I began to realize then what had happened,” he said. The college had warned them that in the event of an earthquake, they should leave the dormitory immediately. A few did rush in when it was safe to grab some clothes to keep warm.
Without any tents or bedding, the students stayed on the football field for the whole night. Rain started falling in the morning, but the students all kept in good order. They simply chatted and shared their feelings and comforted each other.
“Our students seemed to have self-control,” he said. “I heard that hospitals in Chengdu have lots of injured people who jumped out of buildings.”
Now, Diao is mostly worried about the people in Wenchuan County.
“It seems we won’t be able to have classes in one or two day’s time,” said Diao. “I want to become a volunteer at the damage-hit area, or donate my blood to the injured people in hospital. Also, I will write on my blog to keep people calm and encourage them to protect themselves during emergencies.”
