Fukushima rice tests ‘radiation free’ first time since disaster

For the first time since the 2011 disaster, all of the rice harvested in Fukushima Prefecture this year has passed radiation tests and now can be deemed safe for consumption, according to local officials.

Virtually all of the rice harvested in Fukushima in 2014 – or some 360,000 tonnes – has been checked for radiation and met the national standards of less than 100 Becquerel’s per kilogram, Reuters reports.
 
"The fact that the amount of rice that does not pass our checks has steadily reduced in the last three years indicates that we're taking the right steps," said Fukushima official Tsuneaki Oonam, who heads the department that oversees Fukushima rice farming. 
Authorities began testing all rice grown in Fukushima prefecture in 2012, although the amounts harvested over the past years were insignificant. More 190 testing devices are used throughout the prefecture to ensure rice’s safety standards. 
For the last 2 years, some 10 million bags of rice were checked annually. In 2012, 71 bags were found to exceed the safety standards, while in 2013, 28 bags were over the standard, the Asahi Shimbun reports. Rice farmers, according to the newspaper, succeeded in changing the fertilizer used so that radioactive cesium is not absorbed by the rice plant. 
Rice that passes the Food Sanitation Law standards, is labeled as such. Those bags with radiation readings are destroyed. Despite the promise of getting a clean over-all reading, Fukushima prefecture plans to continue the radiation testing program. 
Japan exported its first rice following the disaster last August – a 300-kilogram batch was delivered to Singapore. Fruit exports to Malaysia also resumed last year, according to officials, while in 2012 Fukushima peaches and apples were exported to Thailand.

US scientists expect radioactive water from Fukushima at American coast by April

American scientists beware that radiation from Japan's leaking Fukushima nuclear power plant could reach Pacific coast in the nearest future. Ken Buesseler, a chemical oceanographer at the Woods Hole Oceanographic Institution on Cape Cod, Mass., reported that four coastal monitoring sites in California and Washington have detected no traces of radiation from the Fukushima Dai-ichi nuclear plant destruction - "not yet," he said during a telephone press briefing, but noted that it might reach the coast by April.

Buesseler said no federal or international agencies are monitoring ocean waters from Fukushima on this side of the Pacific, so he has organized volunteer monitors at 16 sites along the California and Washington coasts and two in Hawaii to collect seawater in 20-liter specialized plastic containers and ship them by UPS to his Woods Hole laboratory.

The March 2011 tsunami off Japan flooded the Fukushima Dai-Ichi nuclear plant, causing radiation-contaminated water to spill into the Pacific. Airborne radiation was detected in milk and rainwater in the US soon afterward. But things move much more slowly in the ocean.

"We know there's contaminated water coming out of there, even today," Buesseler said in a video appealing for volunteers and contributions.

In fact, it is the biggest pulse of radioactive liquid dropped in the ocean ever, he said.

"What we don't really know is how fast and how much is being transported across the Pacific," he added. "Yes, the models tell us it will be safe. Yes, the levels we expect off the coast of the U.S. and Canada are expected to be low. But we need measurements, especially now as the plume begins to arrive along the West Coast."

Two different models have been published in peer-reviewed scientific journals predicting the spread of radioactive isotopes of cesium and iodine from Fukushima. One, known as Rossi et al, shows the leading edge of the plume hitting the West Coast from southeast Alaska to Southern California by April. The other, known as Behrens et all, shows the plume hitting Southeast Alaska, British Columbia and Washington by March 2016.

The isotopes have been detected at very low levels at a Canadian sampling point far out to sea earlier than the models predicted, but not yet reported at the beach, said Kathryn A. Higley, head of the Department of Nuclear Engineering and Radiation Health Physics at Oregon State University. The Rossi model predicts levels a little higher than the fallout from nuclear weapons testing in the 1960s. The Behrens model predicts lower levels like those seen in the ocean in the 1990s, after the radiation had decayed and dissipated.

The models predict levels of Cesium 137 between 30 and 2 Becquerels per cubic meter of seawater by the time the plume reaches the West Coast, Higley said.

  • The federal drinking water health standard is 7,400 Becquerels per cubic meter, Leon said.

US Navy sailors sue Fukushima operators for £600m

Nearly 80 US Navy sailors who supported Japan after the Fukushima disaster demanded £612 million (US$1bn) from Tokyo Electric Power Plant (Tepco), operators of Fukushima. According to plaintiffs, over the last three years they have suffered from different diseases as a result of radiation exposure.

An earthquake that was followed by tsunami and nuclear disaster took place March 11,2011. The USS Ronald Reagan super-carrier was sent to the northeast coast of Japan to assist the country.


The vessel crew that includes sailors and support personnel claims that during the operation, called Operation Tomodachi, they were exposed to radioactive plumes. According to them, since the accident they have suffered from different health issues, ranging from cancer to fertility problems.

Their claims were submitted to San Diego District Court in California. Paul C Garner, a lawyer representing the Nevy sailors, says that "they are suing Tepco for negligence in permitting escape of radiation from Fukushima nuclear power plant, strict liability, fraudulent concealment of true facts and a $1 billion medical fund plus compensation."

This is an amended claim, as an earlier version was dismissed by the judge in San Diego last year.

The US government assured that the levels of radiation were too low and the sailors couldn't get their health damaged. The government also published a list of exposure details.

The US Navy spokesman told The Telegraph that after the operation all crew was monitored and the levels of radiation exposure were very low.

Vessels' personnel deny Government's proofs and continue to stand their ground.

Lt Steven Simmons, a 36-year-old administration officer, told that he had fallen ill within months of returning to the US from his deployment on the USS Reagan. He said that doctors didn't do internal and external monitoring of people. He also said that though he heard via intercom that "contaminants" got into water, he had already had his breakfast and had drunk several glasses of water. Mr. Simmons used to be a very healthy man. He used to doing the P90-X work out and claimed the "Stairway to Heaven" in Hawaii. After his return, his health began to decline. Today he is wheelchair bound father of three children. Doctors say that it can't be a radiation poisoning. Otherwise, Lt Simmons would have been affected earlier.

Tepco that is now facing a large number of lawsuits from Fukushima residents doesn't comment on the issue. The company's representative thanks the US for all its help and assures that the company would appropriate all measures, assigned by the Court in US.

Today, three years after the Fukushima disaster, concerns in the region are growing. Local city governments are adopting resolutions that stipulate more intensive testing of coastal seafood. Some scientists think that seaborne radiation from Fukushima will wash up on the US West Coast. Nevertheless, the most of scientists assure that radiation will decay or lessen to the concentrations that don't have any effect on people's health.

US West Coast on high alert against tsunami-washed Japanese invasive species

While winter storms have plunged temperatures across various parts of the United States, the West Coast is bracing itself for an altogether different – yet still very unwelcome – set of seasonal hazards: invading marine life from Japan.
Almost three years after the Tohoku earthquake and tsunami ravaged Japan’s east coast and set off the Fukushima Daiichi nuclear disaster, dislodged debris from the site is still washing up onto American shores. Yet while scientists have downplayed the possibility that the wreckage is contaminated with radiation, they are keeping their eyes peeled for hostile sea creatures hitching rides from across the Pacific. 


The answer is ‘yes,’ there is a real threat,” John Chapman of the Oregon State University’s Marine Bioinvasion Lab told RT in an interview, noting that well over 150 marine species have arrived on the coast over the last year. “These [creatures] have the potential to invade local habitats.”
Currently, government agencies across California, Oregon, and Washington are drafting comprehensive surveys of their coasts in an attempt to determine exactly what species have reached their shores and which, if any, have been able to successfully establish themselves in local habitats.
“We’re still in the discovery phase,” Chapman said. “We’re still getting lots of debris” and even more is expected to arrive during the winter season, which is typically when the majority of the rubble washes ashore. Scientists previously believed that native Japanese marine life could not survive the voyage across the Pacific Ocean, but the results have proven quite the opposite.
“We’ve been wrong on all our predictions so far,” Chapman said.
Over the last two years, entire docks have made their way to the shores of Oregon and Washington, housing dozens of non-native marine life. Meanwhile, other instances have seen fishing vessels surface with entirely different communities of life onboard. Already, scientists and researchers have pinpointed a number of potentially hazardous arrivals.
According to marine biologist Steve Rumrill, of the Oregon Department of Fish and Wildlife (ODFW), two species discovered in the state were on the Global Invasive Species Database’s list of the world’s 100 worst invaders: Wakame, a seaweed native to Japan that began reproducing as soon as it arrived in America, and the Northern Pacific seastar, which he described as a voracious predator that could decimate local shellfish populations.............................http://rt.com/usa/japan-invasive-species-west-coast-587/

TEPCO detects record radiation at Fukushima’s reactor 2, new leak suspected

TEPCO has found a record 1.9 million becquerels per liter of beta ray-emitting radioactive substances at its No.2 reactor. Also radioactive cesium was detected in deeper groundwater at No.4 unit’s well, as fears grow of a new leak into the ocean.
The level of beta ray-emitting radioactivity in groundwater around the crippled Fukushima reactor No. 2 reactor has been rising since November, NHK reported.

Previous the highest level – 1.8 million becquerels (bq/liter), of beta-ray sources per liter - was registered at reactor No.1 on December 13.


Meanwhile, TEPCO’s latest examination of deeper groundwater beneath the #4 reactor's well has raised new concerns that there might be another source of radioactive substances leakage into the ocean.

For the first time, the analysis of water samples taken from a layer 25 meters beneath the No. 4 reactor's well that is facing the ocean has revealed radioactivity in groundwater.

TEPCO investigators detected 6.7 bq/liter of Cesium 137 and 89 bq/liter of strontium as well as other beta ray-emitting radioactive substances.

However, the company’s officials said that it is early to talk about a hotspot of radiation leak and more examinations are needed to prove that. TEPCO suggested that current numbers could be wrong because radioactive substances may have been mistakenly mixed during the process of getting the sample.

Leakage of radiation-contaminated water has been the major threat to Japan’s population and environment from the very beginning of the Fukushima disaster in March 2011.

Only in late July 2013 did TEPCO acknowledge the fact that contaminated water is escaping from basements and trenches of the Fukushima plant into the ocean.

Since then, TEPCO reported about two major leaks of highly radioactive water into the ocean from storage tanks – a 300-ton leak in August and 430 liters in October.

Fukushima debris island the size of Texas floating to the US.

A massive island of debris is slowly making its way to the United States after forming in the wake of the tsunami that rocked Japan back in 2011. The tsunami killed almost 16,000 people in Japan, caused numerous problems at the nuclear plant in Fukushima, and dislodged more than 1.5 million floating objects into the Pacific Ocean. Now, a collection of debris the size of Texas is roughly 1,700 miles off the coast of California. According to the National Oceanic and Atmospheric Administration (NOAA), the debris scattered by the tsunami has been spread around an area of the ocean that’s three times the size of the continental United States. It also said to expect trash to continue arriving on American shores for the next few years. Already, objects such as boats, rooftops, soccer balls, and docks have hit various parts of the West Coast. Even more will arrive with the Texas-sized island, but, more than the trash, scientists are interested in the organisms that could be living on them........http://rt.com/usa/fukushima-debris-island-texas-266/5/11/13--
