Prof.Hayano – “No children were exposed to internal radiation” , Why the lies?

1billion Yen insurance at risk!

Since the nuclear disaster of 2011 in Japan, Professor Hayano’s comments on Twitter have been spotlighted as a source of information from specialists. His presentations addressed to middle and high school students have been highly appraised both in Japan and overseas, and we plan to have him speak to a similar audience at the World Convention.

Professor Hayano of Tokyo University has been in charge of measuring the amount of internal exposure to ionizing radiation for residents of Fukushima Ibaragi prefecture, using Wholebody counter at Hirata central hospital in Hirata village, Fukushima prefecture.  He measured 33,000 residents between October, 2011 and November, 2012.  He announced that he had only found cesium137 in 1% of the residents since last March.  He had measured 10,000 children under 15 years old since last May, but he didn’t detect any C137 in all of them.  He concluded that the reasons for decreasing no. of the residents who have been exposed to cesum137 is well established measuring food system and the residents being much more careful not to eat radioactively contaminated food.

早野教授らは11年10月～12年11月、福島県平田村の病院に設置した「ホールボディーカウンター」と呼ぶ機器を使い、福島県や茨城県などの住民延べ３万2811人を調査した。 成人を含めた約３万３千人では、検出された人の割合は同年３月以降で１％程度だった。 食品の検査が適切に実施され、住民も食事に気を配っていることなどが要因とみている。   
11年11月と同12月は15％から放射性セシウム137が検出された。12年３月、衣服の汚れなどの影響を取り除くため、検査着に着替え て体内被曝量を測る方法に変更した後は平均で１％程度になった。 15歳以下に限ると、12年３～４月に計12人から検出されたが、５月以降は１人も検出さ れなかった。

ご 質問の件ですが、300Bq/Bodyはご指摘のように高すぎると考えています。 ただ、いろいろな自治体で自主的にWBCを導入して測定しているところでも、検出限界はセシウム137,134それぞれ250Bq/Body程度です。 250から300程度が現在のWBCの「検出限界」の限界のようです。  測定時間を長くすれば、時間のルート（平方根）倍で検出限界は下がります。  尿検査はWBCと比べ数倍から数十倍検出限界が低い。 （感度が高い）ということです。

Detectable level is 300Bq/kg for each C134 and C137 at Hirata Hospital which I think it’s set up high. Normally it is between 250-300Bq/kg for each C134 and C137. 

I think 250-300Bq/kg is the best Wholebody counter can measure.  Longer measurement can detect more cesium in the body if the background radiation is low.  Normally the atmospheric dose is high in Fukushima prefecture. 

Therefore, I recommend a urine test which is about 10 times more accurate than wholebody counter.

[…]
Extensive whole-body-counter surveys carried out at the Hirata Central Hospital between October, 2011 and November, 2012, however show that the internal exposure levels of residents are much lower than estimated.

In particular, the first sampling-bias-free assessment of the internal exposure of children in the town of Miharu, Fukushima, shows that the ¹³⁷Cs body burdens of all children were below the detection limit of 300 Bq/body in the fall of 2012.

These results are not conclusive for the prefecture as a whole, but are consistent with results obtained from other municipalities in the prefecture, and with prefectural data.

(Editor’s note)

Miharu-machi can’t be used as an example area because it was one of a few areas in Fukushima prefecture where Iodine tablets were distributed soon after the accident.  Therefore naturally they should have been less affected by the fallout of the disaster comparing to residents in the other areas.

Report – Recent expedition to radioactive ‘hot spot’ shows limited data on contaminated areas

Even though extensive studies have been done to date to record the effects of Mayak’s radioactive wastes on the levels of contamination of the area’s river and lake systems, the bulk of these studies, as the expedition members noted, were performed in relative proximity to the contamination source – on the rivers Techa and Karabolka.

But the plant’s radioactive discharges travel a much longer way, passing through the river system Techa-Iset-Tobol-Irtysh-Ob and ending up, eventually, in the Arctic Ocean. At the same time, there is hardly any monitoring data on the Iset-Tobol-Irtysh-Ob part of that route.

ST. PETERSBURG – A comprehensive report summing up the results of a recent radiation and environmental survey in the territory surrounding Russia’s infamous nuclear reprocessing plant Mayak in Chelyabinsk Region reveals serious gaps in the area’s radiation monitoring of past years – blank spots that must be filled for a full picture of radioactive contamination in an area that has been dubbed the world’s dirtiest radioactive “hot spot.” 

Last spring, an eleven-strong environmental survey expedition traveled to the area around Mayak, the USSR’s first enterprise for industrial production of weapons-grade fissile materials, uranium-235 and plutonium-239, and the birthplace of the Soviet atomic bomb. The group, comprising environmental activists and experts in natural science and technology history, nuclear industry, and radiation control, surveyed the floodplains of the Techa-Iset and Sinara-Karabolka-Iset river systems and the territories of the villages of Muslyumovo, Novomuslyumovo, Russkaya Techa, and other settlements that have been exposed to radioactive contamination as a result of Mayak’s operations and following the so-called Kyshtym disaster of 1957.

A report (in Russian) has now been published, detailing the results of the expedition and concluding with a set of recommendations on ways to mitigate the harmful effects of the consequences of Mayak’s activities on public health and the area’s environment.

The document – entitled “Report on the results of radiation monitoring of rivers and lakes in the area of impact of Production Association Mayak” – compares the latest data with that obtained in previous years, showing a picture of how levels of radioactive contamination have been changing over the years in the areas surrounding Mayak.

The eleven members of the expedition included experts from the S.I. Vavilov Institute for the History of Science and Technology of the Russian Academy of Sciences, the radiation control laboratory of the state enterprise Center for Industrial Safety of the Fuel and Energy Complex, and a St. Petersburg-based testing laboratory. These were responsible for measuring and analyzing the levels of radioactive contamination of some of the Techa floodplains.

An expert with Environmental Rights Center (ERC) Bellona, Bellona’s St. Petersburg branch, and a representative of Greenpeace Russia took part in the expedition as independent observers. ERC Bellona was represented by the nuclear projects expert Alexei Shchukin. 

Altogether during the expedition, 1089 measurements were made of the dose equivalent of external gamma radiation, and 815 measurements of the beta particle emission rate. Experts also took 122 river and lake silt, water, and soil samples.

The radioecological survey covered the riverside lands of the villages of Novogorny, Muslyumovo and Novomuslyumovo, Krasnoisetskoye, Tatar Karabolka, Ust-Karabolka, and Argayash; lands belonging to the state forest fund; condemned lands; rivers (Techa, Zyuzelka, Sinara, Karabolka, Iset, Tobol, Irtysh, and Ob) and their floodplains; and lakes Ulagach and Argayash, and a number of lakes located in the impact zone of Mayak.
