People being tested for radiation exposure
The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Maryland.
Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation.
JONATHAN LINKS: "Of course, we don't know what doses they've received, but the only persons at risk of acute radiation effects are the workers."
For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind released in a nuclear accident.
Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated. He says if the situation is serious enough, officials could take steps like telling people not to eat locally grown food or drink the water.
JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction, the radioactive material was blown over the area, and then settled out of the air into and onto water, plants, fruits and vegetables."
The reactors at Fukushima are on the Pacific coast. But Professor Links says people should not worry about any radioactive material leaking into the ocean.
JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of dilution. So the concentration of radioactivity in the seawater would still be quite low."
Japan is the only country to have had atomic bombs dropped on it. That memory from World War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says.
Next month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry.
A new United Nations report says more than six thousand cases of thyroid cancer have been found. These are in people who were children in affected areas of Belarus, Russia and Ukraine. The report says that by two thousand five the cancers had resulted in fifteen deaths.
The cancers were largely caused by drinking contaminated milk. The milk came from cows that ate grass where radioactive material had fallen.

The financial crisis will be the top issue at this year’s World Economic Forum in Davos, Switzerland. The five – day meeting starts on Wednesday, January 28. More than two thousand five hundred people from ninety-six countries will discuss ways to solve the crisis.
The event gathers some of the world's most powerful political and business leaders at a small ski village in the Swiss Alps. Organizers this week announced a program built around the theme: “Shaping the Post-Crisis World."
But with the world still in crisis , there was news that no famous people from show business will be at the forum this year. Bona, the social activist and lead singer of the Irish rock group U2, usually attends. But he will not be attending this year.
Organizers expect a record forty-one heads of state or government. They include Chinese Premier Wen Jiabao, Russian Prime Minister Vladimir Putin and the prime minister of Kenya, Raila Odinga.
Among those expected from President Obama's new administration is Lawrence Summers, the director of the National Economic Council. Another is Mister Obama's national security adviser, retired general James Jones.
Members of the US Congress are also among the guest list, along with former president Clinten, a favorite at Davos. About sixty percent of those attending are business leaders.
The World Economic Forum will also discuss global warming, investment in low-carbon forms of energy in developing countries and other issues.
Klaus Schwab is the founder and chairman of the forum. He calls this one of the most important gatherings in its thirty-nine year history. He says the financial crisis should be seen as a wake-up call to change systems and ways of thinking, and to re-establish trust.
KLAUS SCHWAB: "We never will move out of the crisis if we do not re-establish confidence which means we have to establish signposts for the future."

For many people – especially those juggling (兼顾) family and work at the same time --- it can be difficult to stick with a college degree. Kathy Bitzthum thought many times about dropping out of her accounting program at Iowa State University: She had two children and a job at Electronic Technology Corp. She’d only enrolled in the first place because her boss would offer her a promotion if she took a few accounting courses.
Because she only had enough time to take one class at a time, it took her seven years to complete the courses her boss asked her to take on. She received the promotion as her boss promised and wasn’t planning to continue a degree. But a request from her father, who was dying of cancer, made her think twice. He said to her, “Kathy, why don’t you just keep going and get your degree?”
Before he passed away, he made her promise that she would finish it. And he made her a promise in turn. Vitzthum’s parents had agreed to give each of their children a valuable gift when they graduated from college, and Vitzthum was obsessed with an antique she’d come across and knew that she couldn’t afford. After she promised to graduate from college, her parents bought her the antique. Her father told her, “I’m not going to be around when you graduate, so I’ll give this to you now. But it doesn’t _________ until you graduate from college.”
Since then, Vitzthum has looked at that antique every day and remembered the promise she had made to her father. Despite a hectic life as a wife, mother and full-time employee, she’s taken one course every semester for the last 19 years. And finally, at the age of 48, she graduated with a bachelor’s degree in accounting --- and she was excited to accept full ownership (所有权) of the antique that she’d borrowed for more than a decade.

For many people, being on the job might just sound like a picnic compared to a day at home filled with housework, meals and childcare. Even for those with a happy family life, home can sometimes feel more taxing than work.
In a new study, researchers at Penn State University found significantly and consistently lower levels of cortisol(皮质醇) released in response to stress, in a majority of subjects when they were at work compared to when they were at home. This was true for both men and women, and parents and people without children.
Both men and women showed less stress at work. But women were more likely to report feeling happier there. Men were more likely to feel happier at home. Experts say there are other reasons why work is less stressful than home for many. “Paid work is more valued in society,” says Sarah Damaske, the lead researcher on the study. “Household work is boring and not particularly rewarding.”
We get better at our job with time and the increased competence means less stress and more rewards. Yet none of us, no matter how long we’ve been doing it, ever truly feels like an expert at parenting or even at marriage.
The support and friendship of co-workers also offer stress relief. At home, meanwhile, stress spreads and accumulates quickly. “That’s the reason why most housewives wish they were the bread earners,” Dr. Damaske says.
Much of the advice to families and couples include the warning to “leave work stress at the office” and even to change our mind-set from work to home, for example, a walk around the block. The recent findings, though, suggest our home life, not our attitude, might be due for some change.
1.Which of the following can replace the underlined word “taxing”?
A. stressful. B. cheerful. C. worthwhile. D. rewarding.
2.What did the research in the second paragraph prove?
A. Men felt better at home.
B. Women felt they had less time.
C. Women were easier to feel happier.
D. Most people felt more stress at home.
3.What do most people think of work at office?
A. It is competitive. B. It improves ability.
C. It can’t relieve stress. D. It doesn’t always pay off.
4.According to the recent findings, what should we change to solve the problem mentioned?
A. Our attitude. B. Our mind-set.
C. Our home life. D. Our working style.
