Nearly two years after a powerful earthquake triggered a leak at Japan's Fukushima Dai-ichi nuclear plant, the effects of that disaster are still being felt on the other side of the planet.

A report released earlier this month by researchers at Stanford University's Hopkins Marine Station found that bluefin tuna caught just off the California coast tested positive for radiation stemming from the incident.

The study looked at the levels of radiocesium, one of the most common results of nuclear fission reactions, in Pacific Bluefun Tuna--largely as way to track the species' migratory patterns as the fish make their cross-oceanic journey in search of prey.


MAFF Permits Rice Planting in Evacuation Zone/Fukushima City Rice Started Being Served for School Lunch

Fukushima Diary Posted by Mochizuki on January 21st, 2013 · 1 Comment Share on twitterShare on linkedinShare on facebookShare on emailMore Sharing Services Ministry of Agriculture, Forestry and Fisheries permitted rice planting in 96 households (73 ha) of evacuation zone in Tamura city Fukushima, where the annual dose is under 20mSv/y. They also permitted 1200 households to produce rice in Fukushima, Soma, Nihonmatsu and Da-te city, where is 380 ha in total. In 2012, rice planting was not permitted in these areas. In order to preserve rice field and the motivation of farmers, MAFF is going to permit rice planting in other evacuation zones (under 20mSv/y) on the requests residents too.

New Wheat Strain Could Ease Food Shortages

Homeland Security News Wire - March 14, 2012

Researchers in Australia have developed a new strain of salt-tolerant wheat that could help minimize food shortages.

Australia is the second largest exporter of grain in the world, but in recent years increased salt levels in the soil have degraded some of the country’s primary wheat-growing regions. In addition, increased salt levels have affected roughly 20 percent of the world’s farm land.

Bloomberg Businessweek reports that to overcome these challenges, Australian scientists have bred salt tolerance into durum wheat, boosting yields by 25 percent in saline soils.

“This work is significant as salinity already affects over 20 percent of the world’s agricultural soils, and salinity poses an increasing threat to food production,” said Rana Munns, one of the study’s co-authors and a scientist with Commonwealth Scientific and Industrial Research Organization, in a statement.

For Japanese Farmers, Lessons From Chernobyl

Scientists from the former Soviet Union have arrived in Japan's Fukushima prefecture to advise locals on farmland decontamination.

One of Japan's most valued agricultural regions, the area was irradiated when three nuclear power plant reactors melted down in the wake of last year's earthquake and tsunami on the country's northeastern coast.

According to Japanese officials, 81,000 hectares of farmland are contaminated at a level above 5,000 becquerels per kilogram, the limit at which rice, by government decrees, cannot be planted.


Citizens’ Testing Finds 20 Hot Spots Around Tokyo

TOKYO — Takeo Hayashida signed on with a citizens’ group to test for radiation near his son’s baseball field in Tokyo after government officials told him they had no plans to check for fallout from the devastated Fukushima Daiichi nuclear plant. Like Japan’s central government, local officials said there was nothing to fear in the capital, 160 miles from the disaster zone.

Then came the test result: the level of radioactive cesium in a patch of dirt just yards from where his 11-year-old son, Koshiro, played baseball was equal to those in some contaminated areas around Chernobyl.

The patch of ground was one of more than 20 spots in and around the nation’s capital that the citizens’ group, and the respected nuclear research center they worked with, found were contaminated with potentially harmful levels of radioactive cesium.

Radioactivity in Japan Rice Raises Worries

TOKYO — Government officials on Saturday ordered more tests after detecting elevated levels of radiation in rice crops near the crippled nuclear power plant at Fukushima.

Radioactive substances have already been discovered in beef, milk, spinach and tea leaves, leading to recalls and bans on shipments. But officials have been especially worried about rice, a staple that makes up a significant part of the Japanese diet. Japan grows most of the rice that it consumes.

Effect of Contaminated Soil on Food Chain Sparks Fears

by Mizuho Aoki - The Japan Times - September 11, 2011

Cesium absorption through roots may have long-term effect on farming

Six months after the nuclear meltdowns in Fukushima Prefecture, the public's awareness of the threat posed by radiation is entering a new phase: the realization that the biggest danger now and in the future is from contaminated soil.

The iodine-131 ejected into the sky by the Fukushima No. 1 power station disaster was quickly detected in vegetables and tap water — even as far away as Tokyo, 220 km south of the plant.

But contamination levels are now so low they are virtually undetectable, thanks to the short half-life of iodine-131 — eight days — and stepped up filtering by water companies.

But cesium is proving to be a tougher foe. The element's various isotopes have half-lives ranging from two to 30 years, generating concern about the food chain in Fukushima Prefecture, a predominantly agricultural region, as the elements wash fallout into the ground.

The root of the problem is, well — roots.

Rice Futures Trigger Circuit Break in Tokyo Debut

Bloomberg - By Jae Hur and Yasumasa Song - August 7, 2011


An official from the Chiba Prefectural Government Offices shows a sack of rice samples bound for radiation tests at a field in Katori City, Chiba Prefecture, Japan.

Rice futures in Tokyo surged on the first day of trading after a seven-decade halt, triggering the bourse to suspend trade, on concern radiation from the stricken Fukushima nuclear plant may spread to crops and curb supply.

No deals were concluded on the Tokyo Grain Exchange after prices hit 18,500 yen per 60 kilograms from the opening, compared with the bourse’s reference price of 13,500 yen. The surge triggered trade to be suspended.

The exchange listed rice contracts today for the first time since the start of World War II to boost flagging volumes and profit. The resumption comes as fallout from the Fukushima Dai- Ichi power plant may spread after it was found cattle had been fed cesium-tainted rice straw.

Beef Contaminated With Cesium Sold at Market - July 13, 2011

Beef from cows from Fukushima Prefecture contaminated with radioactive cesium was sold to restaurants and shoppers in at least five prefectures, according to Tokyo metropolitan government officials.

The officials said July 11 that contaminated beef from six cows raised at a ranch in Minami-Soma was sold in Hokkaido, Chiba, Aichi, Tokushima and Kochi prefectures.

The rancher on July 10 admitted ignoring a prefectural order not to use potentially contaminated feed stored outdoors after explosions at the Fukushima No. 1 nuclear power plant, Fukushima prefectural officials said.

Wholesalers in Tokyo sold the beef to dealers in Tokyo as well as Kanagawa, Shizuoka, Osaka and Ehime prefectures before the meat reached those prefectures, the Tokyo officials said.

The revelations come after Tokyo officials discovered radioactive cesium at levels up to 3,200 becquerels per kilogram, or 6.4 times the national safety limit of 500 becquerels per kilogram, in meat from 11 cows from the same ranch earlier this month. However, beef from the cows did not make it to market.

The beef that did make it to market and consumers' tables was from six cows shipped before the cesium contamination was discovered.
