Tepco excluding Strontium-90 from analyzing nuclides of groundwater and seawater samples

Extremely high level of Tritium and Strontium-90 are starting to be measured from groundwater and seawater, which are also in the increasing trend.

(cf, 500,000,000 Bq/m3 of Tritium and 1,000,000 Bq/m3 of Sr-90 detected from groundwater east side of reactor2 [URL])

However, they are excluding Sr-90 from analyzing nuclides of groundwater and seawater.

From 6/25 to 6/26/2013, they took samples from 3 groundwater observation holes and 16 locations in Fukushima plant port.

For some reason, they are not to analyze the samples for Sr-90 from all the groundwater observation holes or 8 locations in Fukushima plant port according to Tepco.

If seawater and groundwater are contaminated by Sr-90 as well, it could cause the significan effect to the environment.

The reason of not analyzing the samples for Sr-90 is not announced.

Tepco ignore le strontium 90 des nucléides analysés dans les eaux souterraines ou marines

 

Des niveaux extrêmement élevés de tritium et de strontium 90 commencent à être relevés dans les eaux souterraines et marines, ces dernières étant en pente ascendante  (cf. Les eaux souterraines de l’est (= côté mer) du réacteur 2 sont à 500 millions de Bq/m³ de Tritium et 1 million de Bq/m³ de Strontium 90) et ils excluent le Sr 90 de leurs analyses des eaux souterraines et marines.

Entre le 25 et le 26 juin 2013, ils ont pris des échantillons dans 3 trous d’observation et 16 points dans le port de la centrale de Fukushima.
Ils n’analysent pas le Sr 90 de trois trous d’observation et de 8 points du port de la centrale de Fukushima.
Ils n’en donnent aucune justification.
Si les eaux souterraines et marines sont aussi contaminées par le Sr-90, les impacts sur l’environnement vont être très graves.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
