Day 231 So we’re ALL getting internally exposed… even you, Henry

Hey, AP, you forgot to include something below, third paragraph from the end. Here, let me make a correction for you:

…Some radiation from the accident has also been detected in Tokyo and in the United States, but SOME experts say they expect no significant health consequences there. Yet other experts believe there will be major repercussions – to children in particular – as a result of the radiation released from the explosions at three reactors at the Daiichi Nuclear Power plant….

Nuclear radiation from Fukushima twice more than estimated: report

NATIONAL OCT. 28, 2011 – 12:45PM JST ( 63 )

(AP)NEW YORK —

The Fukushima nuclear disaster released twice as much of a radioactive substance into the atmosphere as Japanese authorities estimated, reaching 40% of the total from Chernobyl, a preliminary report says.

The estimate of much higher levels of radioactive cesium-137 comes from a worldwide network of sensors. Study author Andreas Stohl of the Norwegian Institute for Air Research says the Japanese government estimate came only from data in Japan, and that would have missed emissions blown out to sea.

The study did not consider health implications of the radiation. Cesium-137 is dangerous because it can last for decades in the environment, releasing cancer-causing radiation.

The long-term effects of the nuclear accident are unclear because of the difficulty of measuring radiation amounts people received.

In a telephone interview, Stohl said emission estimates are so imprecise that finding twice the amount of cesium isn’t considered a major difference. He said some previous estimates had been higher than his.

The journal Atmospheric Chemistry and Physics posted the report online for comment, but the study has not yet completed a formal review by experts in the field or been accepted for publication.

Last summer, the Japanese government estimated that the March 11 Fukushima accident released 15,000 terabecquerels of cesium. Terabecquerels are a radiation measurement. The new report from Stohl and co-authors estimates about 36,000 terabecquerels through April 20. That’s about 42% of the estimated release from Chernobyl, the report says.

An official at the Nuclear and Industrial Safety Agency, the Japanese government branch overseeing such findings, said the agency could not offer any comment on the study because it had not reviewed its contents.

It also says about a fifth of the cesium fell on land in Japan, while most of the rest fell into the Pacific Ocean. Only about 2% of the fallout came down on land outside Japan, the report concluded.

Experts have no firm projections about how many cancers could result because they’re still trying to find out what doses people received. Some radiation from the accident has also been detected in Tokyo and in the United States, but experts say they expect no significant health consequences there.

Still, concern about radiation is strong in Japan. Many parents of small children in Tokyo worry about the discovery of radiation hotspots even though government officials say they don’t pose a health risk. And former Prime Minister Naoto Kan has said the most contaminated areas inside the evacuation zone could be uninhabitable for decades.

Stohl also noted that his study found cesium-137 emissions dropped suddenly at the time workers started spraying water on the spent fuel pool from one of the reactors. That challenges previous thinking that the pool wasn’t emitting cesium, he said.

 

 

Um, what, “thank you?” A little late, donchya think?

Gov’t to slash upper limit on internal radiation exposure from food

See link below for full article:

The government will tighten the provisional safety limit for annual internal radioactive cesium exposure through food intake from the current 5 millisieverts to 1 millisievert by around April 2012.

[snip]

A Health Ministry report released in July has revealed that each person in the country was estimated to have been internally exposed to an average of about 0.1 millisievert per year of radiation through food intake since the onset of the nuclear crisis.

“Under the current provisional safety limit, consumers are experiencing increased anxiety as they watch radiation measurements. Tightening the safety limit will reassure many people,” said Hisa Anan, secretary-general of the National Liaison Committee of Consumers’ Organizations.

And here’S EX-SKF’s take on it (just the first four paragraphs. Please hit the link and read the rest.)

Lifetime Cumulative Limit of Internal Radiation from Food to Be 100 Millisieverts in Japan

That’s the formal recommendation of the experts on the government’s Food Safety Commission.

External radiation is not counted in this number, as opposed to their draft plan in July which did include external radiation, and it is in addition to the natural radiation exposure (by which is meant pre-Fukushima natural).

The experts on the Commission didn’t rule on the radiation limit for children, leaving the decision to the Ministry of Health and Labor as if the top-school career bureaucrats in the Ministry would know better.

Yomiuri and other MSMs are spinning it as “tightening” the existing provisional safety limits on food.

Cesium flew further than 1200km

(See article with charts at:)

http://fukushima-diary.com/2011/10/cesium-flew-further-than-1200km/

According to the report of Japanese ministry of environment,
Cesium 134 ,137 were measured from refuse incineration ash even in Ogasawara mura,where is 1200km south west to Fukushima plants.

(Bq/Kg)
From the ash trapped by the air filter
Cs134 48.2
Cs137 66.8
Total 115

From the rest of the ash
Cs134 ND
Cs137 13.6
Total 13.6

Sample taken 7/11/2011

There literally is nowhere to evacuate in Japan.

 

Oh boy, has EX-SKF been busy. Here are some of his headlines with links. Stop over there and read these – well worth your time.

 

France’s IRSN New Estimate on Amount of Cesium-137 into the Pacific Ocean: 27,100 Terabequerels, or 20 Times TEPCO’s Estimate

From Jiji Tsushin (10/28/2011):

フランス政府系の放射線防護原子力安全研究所(IRSN)は27日、東京電力福島第1原発事故後の3月21日から7月半ばまでに海に流出した放射性セシウ ム137の総量は2.71京ベクレル(1京は1兆の1万倍)で、東京電力が6月に発表した推計値の20倍に達すると推定した調査報告書を公表した。

On October 27, the Institute for Radiological Protection and Nuclear Safety (IRSN, Institut de Radioprotection et de Surete Nucleaire) of France announced its research report in which the researchers estimated the total amount of radioactive cesium-137 leaked from Fukushima I Nuclear Power Plant into the ocean was 27,100 terrabecquerels from March 21 to mid July. The IRSN estimate is 20 times as much as the estimate announced in June by TEPCO.

Fukushima I Nuke Plant: 2,600 Bq/Liter Tritium in Water Being Sprayed in the Plant Compound

On October 24, TEPCO quietly released the analysis of the water being sprayed in the plant compound, supposedly for fire and dust suppression.

The water comes from the basements of Reactors 5 and 6, and is treated, apparently, by the system that uses reverse osmosis. TEPCO assures us the water is safer than the seawater cleared for ocean bathing, though it does exceed the WHO standard….

Radiation in Japan: 80 to 120 Microsieverts/Hr Bush in Koriyama City, Fukushima

It’s been over 7 months since the Fukushima I Nuclear Power Plant accident started, and it does look like natural concentration of radioactive materials may be happening in eastern Japan.

57.5 microsieverts/hour radiation from the soil in the city-owned land in Kashiwa City, Chiba sounded extraordinarily high when first reported, but maybe not so.

Fukushima Chuo Television (FCT) reported that the radiation level near the ground in a bush right by the railroad station was found to be 80 to 120 microsieverts/hour in Koriyama City, Fukushima Prefecture….

This Is What Passes as “Decontamination” in Fukushima (for That Matter, in Japan)

Date City in Fukushima Prefecture, 60 kilometers northwest of Fukushima I Nuclear Power Plant and with high radiation areas and spots all over the city, has started the city-wide “decontamination” effort on October 26, according to Fukushima Minyunewspaper (10/27/2011). According to the article,

 この日の除染作業では、市が委託した清掃業者が、民家の雨どいにたまった泥などを取り除いたほか、軒先を高圧洗浄機で洗い流した

In today’s decontamination work, the cleaning contractor hired by the city removed the sludge in the rain gutter at a residence, and washed the frontage of the house with a power washer.

That’s called “decontamination” in Japan, instead of “yard cleaning”.

So I looked for any video footage of “decontamination” in Date City. I didn’t find the latest effort, but I did find the ones from this summer, when the city carried out decontamination with the help of volunteers and the advice from Dr. Shunichi Tanaka, former acting commissioner of the Japan Atomic Energy Commission (under the Cabinet Office) and current decontamination advisor to Date City….

Yomiuri: Local gov’t near Tokyo unable to handle “such a high level of radiation” — Cesium clouds spread over many areas of capital — 57 µSv/hr area yet to be decontaminated


“A radiation hotspot in Kashiwa has still not been decontaminated a week after radiation of 57.5 microsieverts per hour was recorded,” reports The Daily Yomiuri.

The city says it cannot handle such a high level of radiation on its own.

“After the outbreak of the nuclear crisis, clouds containing cesium spread over a widespread area, causing relatively high levels of radiation at many locations in the Tokyo metropolitan area,” explained Yomiuri.
