2)現在適用されている放射性セシウムを捕捉する規格は、ろ紙で分離できる粒子(ダスト)を測定対象として作成されたJIS Z 8808「排ガス中のダスト濃度の測定方法」です。 JIS Z 8808 では、ろ紙で分離できない極小の粒子、霧、気体は測定対象外です。
3)JIS Z 8808を用いた実際の測定においては、ろ紙に加えてガス状物質捕集用に2段の純水の捕集ビン+活性炭素といった構成で行われることが多いと思いますが、「2段の純水の捕集ビン+活性炭素」の構成は、原理的に微小な霧状またはガス状の放射性セシウムを 捕捉できるという構成ではないし、捕捉できることが検証された構成でもありません。
4)JIS Z 8808 を適用した測定でバグフィルターでの放射性物質の除去率が99.99%という結果になっています。また、煙突で微小な霧状またはガス状のセシウムは不検出となっています。

3.結論
JIS Z 8808 による排ガス中の放射性物質濃度の測定が正しくない場合、焼却施設から放射性物質を空気中に放出してしまい、土壌を汚染するばかりでなく、人々の内部被曝(気管支→肺→血液→全身)を引き起こしてしまいます。 微小な霧状またはガス状の放射性セシウムを確実に捕捉できることが検証された方法あるいは原理的に間違いなく捕捉できる方法で確認試験を実施して、本当に煙突から放出される。
Highly Contaminated Radio-waste Burning in Samegawa
Could Result Trans-ocean Contamination
Anti-Samegawa Incinertor Mothers
No Incinerator Citizens, Japan
Dear sirs;
Please be noted that we, residents of Fukushima Shirakawa district (southern part of Fukushima prefecture) would perform action against Ministry of Environment's burning project of high contamminated radioactive waste (more than 8000 Bq/kg) on 18th July, here in Samegawa.
Fukushima Disaster is not over, but the Ministry of Environment (=MOE) is trying to bring another contamination plan all over the world. Last fall, MOE secretly ordered Hitachi Zosen to construct a controversial radiowaste incinerator in small village of Samegawa with only 4000 population. Construction has been completed late June, but there had been no prior information about the project, no such public consultation. Furthermore, last week, some landoweners spoke out they never admitted nor signed the contract, but the government mysteriously announced they had all landoweners consent to run the project.
It is the world-first demonstration incinerator, with unproven technology, and even MOE admitted the tchnology is still its experimental stage, but MOE and Hitachi Zosen would not stop the experimental incineration. Rather they are quite hurry because until now no other municipalities accept such dangerous facility. They say radioacitive cesium could be caught by baghouse filtration, but it cannnot catch gaseus substances and small particles like PM2.5 or nano-sized particles. There is no way to stop radioactive cesium emitted from smokestack, it simply get into the atmosphere and travel the gobe.
The location of incinerator is amidst the pastureland, rich in groundwater and forestry. Ironically, the level of radioactive cesium is comparatively low compared to other parts of Fukushima prefecture, and people are still living here, children are living here, cattles are living here. At the same time, people are dying, children are dying, they are having cancers.
How can we tolerate the second contamination by our own government? How can we believe the project of IAEA and nuclear power plant manufacturer? We are so angry. We have right to protect ourseles, our children, our lives and our distrct. There is no legitimacy for polluting project.
We ask you sirs to come to Samegawa on 18th and see what is happening here and what will happen all over the world. Please report our situation to your country so that we can protect our earth together. We are preparig English signboards to tell the people all over the world!!
