福島縣１１處新検出放射性物質

Recently the Asahi News reported the following
文部科学省は８日、放射性ストロンチウムが東京電力福島第一原子力発電所から６２キロ離れた福島市など、福島県内１１カ所の土壌で新たに検出されたことを明らかにした。放射性セシウムが検出されたところでは、微量に見つかるとされており、それが証明された形だ。放射性ストロンチウムには半減期が長いものがあって、体に入ると長期間影響を及ぼす可能性があり、監視が必要だ。
　検出されたのは４月１０日～５月１９日に採取された土壌。福島市では半減期約２９年と長いストロンチウム９０が１キロあたり７７ベクレル、半減期約５０日と短いストロンチウム８９が５４ベクレル検出された。

　最も多かったのは浪江町赤宇木で、それぞれ２５０ベクレルと１５００ベクレル。北西部に３６キロ離れた飯舘村では１２０ベクレルと１１００ベクレルで、これまでに２０キロ圏内で検出されていた値よりも高かった。ほかに田村市、広野町、川内村、南相馬市、二本松市でもストロンチウムが検出された。文科省は採取した土壌をさらに細かく分析するという。

On the 8th, the Ministry of Education, Culture, Sports, Science and Technology clarified that radioactive strontium was newly detected in the soil of 11 places in the Fukushima prefecture such as Fukushima City which was 62 kilos away from the number one nuclear plant of the Tokyo Electric Power Company in Fukushima. The fact that in this place radio-active strontium was found, while it was a bit of strontium and not too much, it was a proof.

Radioactive strontium had a long half - life, and when it entered the body, there was a possibility of long term influence, so it was necessary to be monitored. It was in the soil collected between April 10th to May 19th that was detected. Strontium 90 that had a long half - life of about 29 years was detected in Fukushima City at 77 Becquerel at one kilo, and strontium 89 with a short half-life of 50 days was detected at 54 Becquerel. Most often found was at Namiemachi, it was anywhere from 250 Becquerel to 1500 Becquerel. At the northwest in Iitatemura that was 36 kilos away, it was 120 Becquerel and 1100 Becquerel; it was higher than the value that had been detected in the 20-kilo range so far. Besides, strontium was detected in Tamura City, Hiroyamachi, Kawauchimura, south Soma City, and Nihonmatsu City. The Ministry of Education, Culture, Sports, Science, and Technology said that they would analyze the gathered soil in more detail.

It seems that the Japanese government still has a lot of clean-up work to do.
