New crisis dividing Japanese – dealing with radioactive debris

Japan’s Latest Nuclear Crisis: Getting Rid of the Radioactive Debris, The Atlantic, JUN 4 2012,   A plan to disperse the waste to incineration facilities across the country, meant to instill national unity, is doing the opposite, and further delaying Japan’s ability to move beyond Fukushima. KITA KYUSHU, Japan — Disposing the more than 20 million tons of rubble caused by the March 11 earthquake and tsunami is proving to be a difficult problem for Japan, not least because much of the rubble has been irradiated by the Fukushima nuclear disaster. The government’s plan — to destroy 4 million tons of potentially radioactive earthquake debris in garbage incinerators around the country — is dividing the nation and further delaying the country’s ability to put Fukushima behind it.

Radiation in Japan’s foodstuffs – the invisible hazard

Unlike harmful iodine 131, which disappears in matter of days, caesium 137 has a “half-life” of 30 years and lingers even longer.

Radioactive discharge from the crippled power station fell directly on crops and vegetables, and worked its way into the food chain when fish or animals in affected areas consumed contaminated plants.

Japan’s invisible enemy within TOKYO, Malaysian Insider,  June 2 — Before March 11, 2011, procuring food for an average Japanese household was a pretty straight-forward affair.

Following long-established traditions, a housewife — it is, still, almost always a woman in charge — did her best to ensure that every product brought to the table could be traced to Japanese soil or waters. This, it was widely held, was the best way to avoid eating fish, meat
or produce tainted with dangerous contaminants. Chinese imports were to be avoided whenever possible.
The accident at the Fukushima nuclear power plant, unleashed by a devastating earthquake and tsunami, shattered this age-old faith in the purity of Japanese produce. Continue reading →

High level nuclear waste dump for shores of Great Lakes!

how did governments around the world, citizens like us around the world, science and the nuclear industry, turn a blind eye to the huge buildup of nuclear waste for more than 40 years as we enjoyed the fruits of nuclear power?

the nuclear waste dangers will remain for thousands of years, longer than civilization itself. And right next to the largest fresh-water lake system in the world.

Nuclear waste, tourism don’t mix http://www.lfpress.com/comment/2012/05/25/19800186.html By WAYNE MACDONALD,  May 26, 2012  A packed council chambers in Saugeen Shores, where I live, stood in stunned amazement as its local council- once again – took a huge step toward changing the face of this lakeside community with no discussion, no debate. Absolutely none. Continue reading →

Increased radiation in Tokyo Bay

Radiation  increasing in Tokyo Bay   May 18, 2012 “If the contamination were to spread to fish, it is possible that radioactive isotopes could accumulate when bigger fish feed on smaller ones.” — Hideo Yamazaki
Radioactive contamination from Japan’s Fukushima nuclear disaster has risen sharply in Tokyo Bay over the past several months rather than decline, according to a new study.
Researcher Hideo Yamazaki from Osaka’s Kinki University found that contaminated sludge has accumulated due to runoff into the bay from rivers flowing from highly contaminated regions. This has caused radioactive cesium levels to rise by 1.5 to 13 times since August, Yamazaki says.

Radiation to be measured in monkeys in Fukushima forests

The group plans to target monkeys in southern Minami-Soma in the prefecture, an area that was inside the no-entry zone around the crippled nuclear plant until mid-April. Relatively high radiation levels have been recorded in the area.

“It’s difficult to accurately gauge how much radioactive cesium has
contaminated mountain forests because the substance is easily moved by
rainwater and by other natural conditions,”

Wild monkeys to help gauge Fukushima radiation http://www.yomiuri.co.jp/dy/national/T120511004760.htm The Yomiuri Shimbun, 11 May 12, FUKUSHIMA–Wild Japanese monkeys wearing special collars fitted with dosimeters and Global Positioning System devices will be used to measure radiation levels in the mountain forests of Fukushima Prefecture in an experiment due to start this month.

A group of researchers at Fukushima University plans to start the experiment to determine the dispersal of radiation due to the crisis at the Fukushima No. 1 nuclear power plant and support decontamination work. Continue reading →

Migrating birds from Japan to be tested for radiation

Kamchatka testing migrant birds for radiation Zee News, India, April 30, 2012, Petropavlovsk-Kamchatsky: Migrant birds arriving in Kamchatka from the side of Japan will be tested for radiation, the Kamchatka government said..

.. Up to 1,00,000 geese and about 1 million ducks come to Kamchatka in spring. Many of these birds might have nested on Japanese islands or flown over lands polluted with radiation in the Fukushima nuclear power plant accident in spring 2011, which makes the tests necessary.

The Kamchatka territory already tested migrant birds for radiation in 2011. No radioactive birds were found back then. http://zeenews.india.com/news/eco-news/kamchatka-testing-migrant-birds-for-radiation_772517.html

Canada avoids testing ocean salmon for radiation

Canadians track Japanese tsunami debris, but won’t systematically test salmon for radiation  http://www.straight.com/article-672746/vancouver/canadians-track-japanese-tsunami-debris-wont-systematically-test-salmon-radiation  by Charlie Smith   April 29, 2012 The Maritime Museum of B.C. has created a Facebook page devoted to collecting photos of debris from last year’s Japanese tsunami.

The majority of the material floating across the Pacific Ocean is not expected to arrive in B.C. until 2013 and 2014.

What I find interesting is that there still doesn’t appear to be a Facebook page concerning the potential effect of the Fukushima nuclear accident on the Canadian food supply.

Earlier this month, Straight reporter Carlito Pablo wrote an article noting that the Canadian Food Inspection Agency has no plans to systematically test next year’s wild salmon for radioactivity.

These fish travel through the same waters as the flotsam and jetsam coming from Japan, where a devastating nuclear accident crippled the Fukushima power plant.

It’s okay to keep records of the garbage—but as far as the Conservative government is concerned, it appears to be not okay to examine if any of it is ending up in our digestive tracts.

Salp invasion cuts nuclear power output

Jellyfish-like creatures force California nuclear power plant to curtail operations By Steve Chawkins / Los Angeles Times, April 26, 2012 LOS ANGELES — Strange, jellyfish-like creatures swarming a coastal nuclear power plant: It might sound like the premise of a cult horror flick, but the invasion has prompted officials at the Diablo Canyon facility in San Luis Obispo, Calif., to curtail operations for at least a few days.

The plant’s operator, Pacific Gas & Electric, cut power generation from one of the plant’s two reactors to 25 percent of its capacity, spokesman Tom Cuddy said Wednesday. The other reactor was shut down this week for what PG&E described as routine refueling and
maintenance, a procedure that could take about a month.

Workers on Monday discovered an influx of the creatures, called salp, clogging screens that are used to keep marine life out of the sea water used as a coolant, Cuddy said. Often thronging many square miles of ocean in huge, gelatinous masses, salp are tubular, transparent organisms that can be roughly the size of a human thumb. No one knows how many are at the Avila Beach plant or how long they will remain…

.. Jellyfish swarmed Diablo Canyon in 2008, triggering a steep, sudden decrease in power generation. Over the years, they have been a problem at nuclear plants in the U.S., Japan, Israel andScotland. …. http://news.bostonherald.com/news/national/west/view/20120426jellyfish-like_creatures_force_california_nuclear_power_plant_to_curtail_operations/srvc=home&position=recent

Cesium 137 and the follies of Chernobyl and Fukushima

The Fukushima Nuclear Disaster Is Far From Over   HUFFINGTON POST, Robert Alvarez, Senior Scholar, Institute for Policy Studies, 22 April 12, “….It’s been 26 years, since the Chernobyl reactor exploded and caught fire releasing enormous amounts of radioactive debris — seriously contaminating areas over a thousand miles away. Chernobyl revealed the folly of not having an extra barrier of thick concrete and steel surrounding the reactor core that is required for modern plants, in the U.S., Japan and elsewhere. The Fukushima Dai-Ichi accident revealed the folly of operating several nuclear power plants in a high consequence earthquake zone while storing huge amounts of highly radioactive spent fuel in vulnerable pools, high above the ground.

What both accidents have in common is widespread environmental contamination from cesium-137. With a half-life of 30, years, Cs-137 gives off penetrating radiation, as it decays and can remain dangerous for hundreds of years. Once in the environment, it mimics potassium as it accumulates in the food chain. When it enters the human body, about 75 percent lodges in muscle tissue, with, perhaps, the most important muscle being the heart.http://www.huffingtonpost.com/robert-alvarez/the-fukushima-nuclear-dis_b_1444146.html

Uranium mining damages health of workers and environment

the World Health Organisation (WHO) acknowledges that Radon, which is a heavy gaseous radioactive chemical, is the second cause of lung cancer after smoking.

Uranium, even when purified, Chareyron said is radioactive and miners cannot really be protected from it.

Concerns over uranium mining New Era, 12 Apr 2012 –  by Irene Hoaës WINDHOEK – Renewed concern has been expressed regarding uranium mining activities along the coastal areas and its impact on the environment following tests undertaken by the Commission for Independent Research and Information about Radiation (CRIIRAD) and EARTHLIFE Namibia.

These mining activities have a direct bearing on people’s health as they reportedly cause cancer, especially to people that get exposed to them.

According to CRIIRAD, people that spend 30 minutes to 35 hours at a distance below 25 meters from the waste rock dump, would receive an external radiation dose above the trivial dose of 10 microsieverts per year.

One of the main concerns is uranium concentrates found in underground water sources and on sediments in areas where Rössing and the Langer Heinrich mines are found, especially along the Khan and Gawib rivers.

According to Bruno Chareyron, a Nuclear Physics Engineer and Director of the CRIIRAD Laboratory, the radioactive tailings (waste) of the mines are not covered and dust particles from the tailings are accumulating on bushes and slopes.

“When it rains, this dust is even washed off the waste rock dumps that are situated next to the river banks and therefore deposited into the river system,” the nuclear engineer said. Continue reading →

In the world of birds, radiation is more damaging to females

the tertiary sex ratio (here defined as the proportion of males among adults) was skewed towards an excess of males across 48 different bird species. This finding is in accordance with lower adult survival rates in females compared to males previously reported for barn swallows in contaminated areas around Chernobyl …..

Female barn swallows suffer differentially from the mortality costs of radiation, with male adult survival being reduced by 24%, while female survival is reduced by 57% in contaminated areas compared to controls 

Elevated Mortality among Birds in Chernobyl as Judged from Skewed Age and Sex Ratios PLoS One 13 April 12, “….Radiation has negative effects on survival of animals including humans, although the generality of this claim is poorly documented under low-dose field conditions.

Because females may suffer disproportionately from the effects of radiation on survival due to differences in sex roles during reproduction, radiation-induced mortality may result in
male-skewed adult sex ratios. Continue reading →
