Text 2 A deal is a deal-except,apparently,when Entergy is involved.The company,a major energy supplier in New England,provoked justified outrage in Vermont last week when it announced it was reneging on a longstanding commitment to abide by the strict nuclear regulations.Instead,the company has done precisely what it had long promised it would not challenge the constitutionality of Vermont’s rules in the federal court,as part of a desperate effort to keep its Vermont Yankee nuclear power plant running.It’s a stunning move.The conflict has been surfacing since 2002,when the corporation bought Vermont’s only nuclear power plant,an aging reactor in Vernon.As a condition of receiving state approval for the sale,the company agreed to seek permission from state regulators to operate past 2012.In 2006,the state went a step further,requiring that any extension of the plant’s license be subject to Vermont legislature’s approval.Then,too,the company went along.Either Entergy never really intended to live by those commitments,or it simply didn’t foresee what would happen next.A string of accidents,including the partial collapse of a cooling tower in 207 and the discovery of an underground pipe system leakage,raised serious questions about both Vermont Yankee’s safety and Entergy’s management–especially after the company made misleading statements about the pipe.Enraged by Entergy’s behavior,the Vermont Senate voted 26 to 4 last year against allowing an extension.Now the company is suddenly claiming that the 2002 agreement is invalid because of the 2006 legislation,and that only the federal government has regulatory power over nuclear issues.The legal issues in the case are obscure:whereas the Supreme Court has ruled that states do have some regulatory authority over nuclear power,legal scholars say that Vermont case will offer a precedent-setting test of how far those powers extend.Certainly,there are valid concerns about the patchwork regulations that could result if every state sets its own rules.But had Entergy kept its word,that debate would be beside the point.The company seems to have concluded that its reputation in Vermont is already so damaged that it has noting left to lose by going to war with the state.But there should be consequences.Permission to run a nuclear plant is a poblic trust.Entergy runs 11 other reactors in the United States,including Pilgrim Nuclear station in Plymouth.Pledging to run Pilgrim safely,the company has applied for federal permission to keep it open for another 20 years.But as the Nuclear Regulatory Commission（NRC）reviews the company’s application,it should keep it mind what promises from Entergy are worth.27.By entering into the 2002 agreement,Entergy intended to

A.obtain protection from Vermont regulators.
B.seek favor from the federal legislature.
C.acquire an extension of its business license.
D.get permission to purchase a power plant.

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.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 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 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. 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 result of radiation absorbed by its grandparents.
Radiation can hurt us.We must know the truth.

According to the passage,the danger of nuclear power lies in________.
A:nuclear mystery
B:radiation detection
C:nuclear radiation
D:radiation level
