1,140 Bq/Kg of Strontium-90 in the main gate of Fukushima plant, 8,950,000 Bq/Kg of Cs-134/137 from vegetation

According to the study of Colorado State University, Vienna University of Technology and Graduate School of Arts and Sciences, The University of Tokyo, 1,140 Bq/Kg of Strontium-90 was measured in the main gate of Fukushima plant.

The sample is vegetation, sampling date was 12/21/2011.
1,070 Bq/Kg of Sr-90 was also measured in the same location.

The sample is soil, sampling date was 12/21/2011 as well.
Also, 85 Bq/Kg of Sr-90 was measured from soil in Yokohama, where is in the south of Tokyo.

 

About Cesium-134/137, the readings are desperately high.

At 1.5 km from Fukushima plant, 4,350,000 Bq/Kg of Cs-134 and 4,600,000 Bq/Kg of Cs-137 were measured from soil.

In total, it was 8,950,000 Bq/Kg and the sampling date was 12/21/2011.

At 4.3 km from Fukushima plant, 2,890,000 Bq/Kg of Cs-134 and 3,120,000 Bq/Kg of Cs-137 were measured from vegetation.

In total, it was 6,010,000 Bq/kg and the sampling date was 12/21/2011.

In Yokohama, 50,000 Bq/kg of Cs-134 and 55,000 of Cs-137 were measured from soil too.
In total, it was 105,000 Bq/Kg and the sampling date was 7/25/2011.

1 140 Bq/kg de strontium 90 à l’entrée principale de la centrale de Fukushima, 8 950 000 Bq/kg de Cs 134/137 dans la végétation

 

Selon une étude conjointe de la Colorado State University, de la Vienna University of Technology and Graduate School of Arts and Sciences et de l’Université de Tokyo, 1 140 Bq/kg de Strontium 90 ont été relevés à l’entrée principale de la centrale de Fukushima.

L’échantillon est végétal, sa date de ramassage est le 21 décembre 2011.
1 070 Bq/kg de Sr 90 ont aussi été relevés au même endroit.

L’échantillon de sol est de la même date.
85 Bq/kg de Sr 90 ont aussi été relevés dans du sol de Yokohama, au Sud de Tokyo.

Concernant les césium 134/137, les relevés sont désespérément élevés :

à 1,5 km de la centrale de Fukushima, 4 350 000 Bq/kg de Cs 134 et 4 600 000 Bq/kg de Cs 137 ont été relevés dans le sol.
Au total, il y avait 8 950 000 Bq/kg dans cet échantillon du 21 décembre 2011.

A 4,3 km de la centrale de Fukushima, 2 890 000 Bq/kg de Cs 134 et 3 120 000 Bq/kg de Cs 137 étaient relevés dans la végétation.
Au total, il y avait 6 010 000 Bq/kg, toujours pour ce 21 décembre 2011.

Dans le sol de Yokohama, 50,000 Bq/kg de Cs 134 et 55 000 de Cs 137.
Au total, 105 000 Bq/kg,  au 25 juillet 2011.
