The deadly earthquake and tsunami (海啸) that struck Japan on March 11 damaged two nuclear power stations. Officials are now working to prevent dangerous radiation from poisoning the air in the area surrounding the Fukushima Daiichi plant. The Japanese government has ordered people living within 12 and a half miles of the plant to evacuate, and asked those living 12 and a half to 20 miles away to stay indoors.
Nuclear power plants create energy using a chemical reaction that produces large amounts of heat. Reactors(反应堆)in Japan have many long, thin rods, called fuel rods(棒), which must be kept cool.
If the reactor’s fuel rods aren’t cooled, the reaction can burn out of control. That’s what happened at the two Japanese plants after the quake caused a power failure and the cooling systems malfunctioned(发生故障). This overheating could cause radiation to escape and sicken many people.
Japan’s 54 nuclear reactors are built to withstand the many small or moderate earthquakes the country faces each year. But Friday’s earthquake was one of the most severe earthquakes ever recorded.
People exposed to unsafe levels of radiation have a higher than normal risk of getting cancer. The Japanese government has been distributing potassium iodide(碘化钾)pills to people in the surrounding areas to protect those who may have come in contact with radiation from the power plant. The pills flood the body with healthy potassium iodide. The potassium iodide works to crowd out “bad” iodine in the body that may have been poisoned by radiation.
On Tuesday morning, 750 workers left the Fukushima Daiichi plant. However, 50 workers stayed behind to use sweater to cool the fuel rods. These dedicated employees are risking their own lives to save many others.
On Thursday, officials used helicopters, fire trucks, and water cannons to spray water on the reactors to cool the fuel rods. But it’s not clear whether these efforts were successful. Officials are now working on a power line to restore electricity to the plant. They hope this will help restart the plant’s cooling system and stop the fuel rods from leaking radiation.

Linus Pauling，the only person who has won two undivided Nobel Prizes，was born in Portland，Oregon. He attended Washington High School but because of an unimportant detail he did not receive his diploma until 1962，long after he had received his Bachelor’s degree in chemical engineering from Orgon State College in 1922. He had chosen to study his major because he could get a good job with it.

He won the Nobel Prize for Chemistry in 1954 for his research into the nature of the chemical bond and its application to the explanation of the structure of complex substance. His interest in the “behavior” of molecules(分子) led him from physical chemistry to biological chemistry，especially of the human body. He began with proteins and their main parts，the amino acids(氨基酸)，which are called the“building blocks of life”．In 1950，he constructed the first satisfactory model of a protein molecule，a discovery very important to the understanding of the living cell.

During World WarⅡ，Pauling was a member of the Research Board for National Security，for which he was awarded the Presidential Medal of Merit in 1948. However，the use of the atomic bomb near the end of the war turned Pauling in a new direction. Having long worked on the structure of molecules，he took an immediate interest in the deadly effects of nuclear fallout on human molecular structures.

From then on，Pauling protested the production of the hydrogen bomb and supported the prevention of the spread of nuclear weapons. Through his efforts，The Nuclear­Test­Ban Treaty，declaring all nuclear tests to be illegal except underground ones，came into effect on October 10,1963，the same day Linus Pauling was awarded the Nobel Peace.
