Radiation found in Tokyo water, food near nuclear plant

FUKUSHIMA, Japan (AP) — Japan said radiation levels in spinach and milk from farms near its tsunami-crippled nuclear complex exceeded government safety limits, as emergency teams scrambled Saturday to restore power to the plant so it could cool dangerously overheated fuel.

The food was taken from farms as far as 65 miles (100 kilometers) from the stricken plants, suggesting a wide area of nuclear contamination.

The Japanese government also reports that trace amounts of radioactive iodine were detected in tap water in Tokyo and five other areas.

A government ministry reported Saturday that small amounts of the iodine was found in tap water in Tokyo and five other prefectures. The ministry says the amounts did not exceed government safety limits but usual tests show no iodine.

But the findings add to public concerns about radiation leaking from the Fukushima nuclear power plant crippled by the earthquake and tsunami.

While the radiation levels in spinach and milk exceeded the limits allowed by the government, Chief Cabinet Secretary Yukio Edano insisted the products "pose no immediate health risk."

The news of contaminated food came as Japan continued to grapple with the overwhelming consequences of the cascade of disasters unleashed by a 9.0-magnitude earthquake on March 11. The quake spawned a tsunami that ravaged Japan's northeastern coast, killing more than 7,300 people and knocking out backup cooling systems at the nuclear plant, which has been leaking radiation.

Nearly 11,000 people are still missing.

The tainted milk was found 20 miles (30 kilometers) from the plant, a local official said. The spinach was collected from six farms between 60 miles (100 kilometers) and 75 miles (120 kilometers) 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 testing was being done on other foods, Edano said in Tokyo, and if tests 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 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, the latter being a longer lasting element and can cause more types of cancer. But only iodine was detected Thursday and Friday, a Health Ministry official said.

Officials from Edano on down tried to calm public jitters, saying the amounts detected were so small that people would have to consume unimaginable amounts to endanger their health.

Edano said someone drinking the tainted milk for one year would consume as much radiation as in a CT scan; for the spinach, it would be one-fifth of a CT scan. A CT scan is a compressed series of X-rays used for medical tests.

"Can you imagine eating one kilogram of spinach every day for one year?" State Secretary of Health Minister Yoko Komiyama said. One kilogram is a little over two pounds.

Why eat 2 pounds of spinach every day for a year? Eat any the rest of the foodstuffs on a veggie plate: snow peas, corn, broccoli, whatever--it's ALL radioactive, give or take a few counts per second of decay energy. Point is that the radioactive isotopes are spread far and wide and the 'exclusion zone' will be huge, and this stuff will be concentrating in food.

Worse is that some isotopes dissolve in water. And further concentrate in animals--the Iodine in milk will increase as the cows eat more toxic grass--this just happened a week ago--check back for way-higher levels. And the fish the Japanese will increasingly depend on (with land loss) under the plume over the ocean--bad news.

It's misleading to compare this at all to X-rays and CAT scans--that's energy passing through the body, not radioactive particles ingested to stay inside our bodies hosing us internally with radiation. You can fool rural Japanese and some journalists, but you can't fool Southerners...or can you?

There's a lot of nuclear plants in the region--add Oconee in SC the list of nearby threats, too, but all these releases get in our food and our food here comes from everywhere. Cancer Up! Get the fuel here in dry casks and phase out these risky things. We've been warned, again.

To better understand radioactive particles concentrating in food, do the simple math. One week and you need to eat over two pounds a day for a heavy dose; after 10 weeks, about 0.2 pounds of spinach for the same dose if the radiation concentrates at the same rate. After 100 weeks, a couple of years--you eat spinach every now and then and you get a HUGE dose. Hopefully, the spinach dies before ti gets so radioactive it's in the markets.

Truth is, the radioactive amounts are quite low now because the wind is going the other way (to sea) and it hasn't rained much. This quiet disaster--no fires or explosions--this poisoning of humanity's breadbasket--that's from power plants that were to make electricity Too Cheap to Meter. And TVA is building more, here?

And what of terrorism? Their fuel storage can't take an RPG hit. Of course terrorists know that, like Libya's squads. Let's get smart and get these nukes cooled and covered while we can. WE can all take turns getting dosed cleaning up the mess--like Osaka and TOkyo firemen--if we don't.
