MEXT Showed Radioactive Contamination Levels 20% Too Low, Correct Data Published On April 16, 2012

MEXT showed the contamination level lower than actual by 20% (Fukushima Diary, April 16, 2012):

Ministry of Education, Culture, Sports, Science and Technology admitted their monitoring data of sea water and sea ground around Fukushima plants were shown lower than actual by 20% at maximum and published the correct data on 4/16/2012.

The manipulated data was from March to August.

MEXT explains it was only cesium 134 that they miscalculated, which is because cesium 134 doesn’t produce only gamma ray, it takes time to analyze it accurately. They state, “It was an emergency, it was more important to analyze more samples than analyzing accurately. ”

文部科学省の説明では、実際よりも低く算出されていたのはセシウム134で、これは同時に複数の放射線を出すため、分析に時間がかかるためにそのことを考 慮しなかったのが原因だと述べています。緊急時なので、正確性を期すよりもより多くの試料を分析することの方が重要だったと説明しています。
