Japan cites radiation in milk, spinach near plant
FUKUSHIMA, Japan (AP) - In the first sign that contamination from Japan's stricken nuclear complex had seeped into the food chain, officials said Saturday that radiation levels in spinach and milk from farms near the tsunami-crippled facility exceeded government safety limits.
Minuscule amounts of radioactive iodine also were found in tap water Friday in Tokyo and elsewhere in Japan - although experts said none of those tests showed any health risks. The Health Ministry also said that radioactive iodine slightly above government safety limits was found in drinking water at one point Thursday in a sampling from Fukushima prefecture, the site of the nuclear plant, but later tests showed the level had fallen again.
Six workers trying to bring the Fukushima Dai-ichi plant back under control were exposed to more than 100 millisieverts of radiation - Japan's normal limit for those involved in emergency operations, according to Tokyo Electric Power Co., which operates the complex. The government raised that limit to 250 millisieverts on Tuesday as the crisis escalated.
Officials said the crisis at the plant appeared to be stabilizing, with near-constant dousing of dangerously overheated reactors and uranium fuel, but the situation was still far from resolved. Japan's military planned to start dousing one troubled reactor - Unit 4 - for the first time shortly after daybreak today.
"We more or less do not expect to see anything worse than what we are seeing now," said Hidehiko Nishiyama of the Nuclear and Industrial Safety Agency.
Japan has been grappling with a cascade of disasters unleashed by the 9.0-magnitude earthquake on March 11. The quake spawned a tsunami that ravaged Japan's northeastern coast, killing more than 7,600 people and knocking out cooling systems at the Fukushima Dai-ichi nuclear plant, causing the complex to leak radiation.
More than 11,000 people are still missing, and more than 452,000 are living in shelters.
Chief Cabinet Secretary Yukio Edano, meanwhile, insisted the contaminated foods "pose no immediate health risk."
An expert in the United States also said the risk appeared limited and urged calm.
"The most troubling thing to me is the fear that's out of proportion to the risk," said Dr. Henry Duval Royal, a radiologist at Washington University Medical School.
The tainted milk was found 20 miles from the plant, a local official said. The spinach was collected from six farms between 60 miles and 75 miles to the south of the reactors.
Those areas are rich farm country known for melons, rice and peaches, so the contamination could affect food supplies for large parts of Japan.
More tests was being done on other foods, Edano said, and if they show further contamination, then food shipments from the area would be halted.
Officials said it was too early to know if the nuclear crisis caused the contamination, but Edano said air sampling done near the dairy showed higher-than-normal radiation levels.
Iodine levels in the spinach exceeded safety limits by three to seven times, a food safety official said. Tests on the milk done Wednesday detected small amounts of iodine-131 and cesium-137. High levels of iodine are linked to thyroid cancer, one of the least deadly cancers if treated. Cesium is a longer-lasting element that affects the whole body and raises cancer risk. But only iodine was detected Thursday and Friday, a Health Ministry official said.
