Now, Radioactive Sewage Sludge from #Fukushima City

Fukushima I Nuke Plant has been one big "dirty bomb".

After Koriyama City's sewage treatment center was tested positive for high level of radioactive cesium in the sewage sludge and slag and the sludge had been already sold (my post here and here), Fukushima Prefecture ordered the testing in other 19 similar treatment centers in Fukushima. 18 out of 19 centers were found to have high concentration of radioactive cesium.

What a surprise.

At one facility in Horikawa-machi in Fukushima City, 446,000 becquerels per kilogram of radioactive cesium were found. At Koriyama, it was 26,400 becquerels per kilogram.

They say they'll have to find out where the sludge has gone. And at one of them, the facility in Fukushima City above, radioactive sludge may have nowhere else to go but spill into the river as soon as May 20.


Koriyama City is 59 kilometers west of Fukushima I Nuclear Power Plant, and Fukushima City, prefectrual capitol, is 62 kilometers northwest of the plant. (Distance with the calculator at this site.)

Koriyama alone sold 928 tons of radioactive sewage sludge in 50 days to Sumitomo Osaka Cement. I hate to think how much total that these treatment facilities in Fukushima may have sold.

Are other prefectures testing their sewage treatment facilities and tracking the shipment? I don't think radioactive fallout stops at the Fukushima border...

From Asahi Shinbun (12:58AM JST 5/9/2011):

 福島県郡山市の下水処理施設の下水汚泥などから高濃度の放射性セシウムが検出された問題で、県は8日、福島市の施設の汚泥からも、より高濃度の放射性セ シウムが検出されたと発表した。県内の19施設を調査した結果、18施設で検出。原発事故の影響が県内の広範囲に及んでいる可能性をうかがわせる。

Following the detection of high concentration of radioactive cesium in the sewage sludge at one of the sewage treatment centers in Koriyama City, the Fukushima Prefectural government announced on May 8 that even higher concentration of radioactive cesium was found in the sewage sludge at a treatment center in Fukushima City. 18 out of 19 facilities tested for radioactive materials were found to have radioactive cesium, hinting [here you go, Asahi's understatement No.1] that the Fukushima I Nuke Plant accident is affecting a wider area in Fukushima.


The Prefectural government will track where the sewage sludge from the facilities has been shipped. The national government is still in the process of establishing the standard for treatment of the radioactive sewage sludge [understatement No.2; the national government was caught, again, flat-footed], so the Fukushima prefectural government will decide how to treat and dispose the radioactive sewage sludge. Sewage treatment facilities in Fukushima have stopped processing the sewage sludge, and if the national policy on the radioactive sewage sludge is not forthcoming, that will result in further delay in sewage treatment

 郡山市の県中浄化センターでは4月30日の調査で、汚泥から1キロあたり2万6400ベクレルの放射性セシウムを検出。その後、19施設を調査した結 果、福島市の堀河町終末処理場の汚泥から同44万6千ベクレルの放射性セシウムが検出された。郡山市の別の施設でも汚泥から高い値を検出。いわき市の施設 では、原発事故前は検出されなかった汚泥の燃え殻から3万5700ベクレルを検出した。

At a sewage treatment plant in Koriyama City, 26,400 becquerels per kilogram of radioactive cesium was detected on April 30. After conducting the testing at 19 facilities, 446,000 becquarels per kilogram of radioactive cesium was detected at a facility in Fukushima City (Horikawa-machi final treatment center). They also found a high concentration of cesium in the sewage sludge at another facility in Koriyama City. At a facility in Iwaki City, 35,700 becquerels per kilogram of cesium was found in the incinerated sludge [slag?].


As to the high level of radioactive cesium at the Horikawa-machi facility, the Fukushima prefectural government thinks it is because of the higher percentage of rainwater at the facility.


According to Fukushima City that manages this facility, they have stopped the dehydration treatment and shipment of the sewage sludge after the news of the Koriyama treatment facility, and the sewage sludge is being stored in a container at the premise. Fukushima City says, "Unless we resume the treatment, the container will be full by May 20, and the sewage sludge has nowhere to go but spill into the river."

into the river as soon as May 20.

do you mean march 20?

merci beaucoup

Never mind my previous comment: I had not read all the post. Thank you.

Accurate translation very much appreciated, Reverse Spring. Thank you.

Sadly this is just the beginning of another nuclear nightmare for all of us. Compassionate thoughts go out to all Japanese caught up in the corporate spin that cares nothing for humanity.
