It is the first report that home-grown food has been contaminated by radioactivity, largely Iodine(碘)-131, since the ministry ordered radiation( powerful and harmful rays that are sent out from radioactive substances) tests on food and water at the end of March in 14 mainland regions including Beijing, Tianjin, and some coastal provinces.
Sample inspections conducted on Tuesday found low levels of radioactive iodine in spinach( a kind of green vegetables) planted in Beijing, Tianjin and Henan province --- about 1-3 becquerels per kilogram (Bq/kg), the statement said.
"The contamination level detected is too low to be harmful to public health," it said.
According to health experts, radioactive iodine can accumulate in humans once ingested in high concentrations and increases the risk of thyroid cancer. But it decays naturally within weeks.
Leafy vegetables grown in the open like spinach, lettuce and leek are among the first foods to be tainted by radioactive deposits.
Raw milk is also susceptible to radioactive contamination as livestock feed on grass.
Tests carried out in March showed spinach and milk taken from farms near Japan's nuclear-stricken area had exceeded(go beyond) government-set safety limits for radiation.
No cases of tainted water or milk have been reported in China but the ministry vowed to further strengthen monitoring.
Wang Zhongwen, a researcher at the China Institute of Atomic Energy's radiation safety department, told China Daily on Wednesday that currently China only had the means to conduct food radiation tests in a few regions.
The statement also said that recent rain in Beijing and Tianjin meant radioactive substances could have fallen on vegetables.
Chen Jicang, a vegetable dealer in Beijing, said on Wednesday that concerns are growing among consumers, businesses and governments across the world.
"We have yet to see any impact on our business from the radiation, but we will keep a close eye on how the issue develops," he said.
He added that most vegetables consumed in Beijing are produced locally, and he might switch to other varieties if spinach sales suffer.
Yang Guoshan, a researcher of radiation medical science at the Academy of Military Medical Sciences, said people could safely eat products that contain low levels of Iodine-131.
"The radiation level is so low that residents don't need to spend any extra effort on cleaning them," he said.
Gao Jie, a 52-year-old resident in Tianjin said she is deeply worried because spinach is a staple part of her family's diet.
"If spinach is radioactive, is there any possibility that other types of vegetables are safe?"
Trace levels of radioactive isotope cesium-137 and -134 were detected in the air in 21 provinces and regions on Wednesday, up from 17 on Tuesday, according to China's National Nuclear Emergency Coordination Committee.

When it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate（light）me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share.
When I was in the eighth grade, I had a friend. We were shy and “too serious” about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say:“Let’s start with a train whistle today.” We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changing into social creatures and the stories and poems stopped.
When I lived for a time in London, I had a friend, He was in despair(disappointment)and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted. We gave London to each other.
For almost four years I have had remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other’s dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think:“Yes, I must tell….”We have never met.
It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist，who will only fill up the healing silence necessary to those darkest moments in which I would rather be my own best friend.

Forget Twitter and Facebook, Google and the Kindle. Television is still the most influential medium around. Indeed ,for many of the poorest regions of the world, it remains the next big thing——finally becomes globally available. And that is a good thing, because the TV revolution is changing lives for the better.
Across the developing world, around 45% of families had a TV in 1995; by 2005 the number had climbed above 60%. That is some way behind the U.S. , where are more TVs than people, and where people now easily get access to the Internet. Five million more families in sub-Saharan Africa will get a TV over the next five years. In 2005 , after the fall of the Taliban（塔利班）,which had outlawed TV, 1 in 5 Afghans had one. The global total is another 150 million by 2013——pushing the numbers to well beyond two thirds of families.
Television’s most powerful effect will be on the lives of women. In India, researchers Robert Jensen and Emily Oster found that when TVs reached villages, women were more likely to go to the market without their husbands’ approval and less likely to want a boy rather than a girl. They were more likely to make decisions over child health care. TV is also a powerful medium for adult education. In the Indian state of Gujarat, Chitrageet is a popular show that plays Bollywood songs with words in Gujarati on the screen. Within six months, viewers had made a small but significant improvement in their reading skills.
Too much TV has been associated with violence, overweight and loneliness. However, TV is having a positive influence on the lives of billions worldwide. K^S*5U.C
