Austrian Meteorological Agency”16,700 Peta Bq of Xe133 released, 2.5 times much as Chernobyl, the largest in history”

According to The Central Institution for Meteorology and Geodynamics of Austria, 16,700 Peta-Bq of Xe-133 was released into the environment. It was the largest civilian noble gas release in history, exceeding the Chernobyl noble gasrelease by a factor of 2.5.

It started leaking at 15:00 JST of 3/11/2011, when was immediately after the earthquake.

They reported this below,

Regarding the radioactive noble gas Xenon‐133, the results indicate an emission of 16700 Peta‐Becquerel (1 Becquerel is one radioactive decay persecond, 1 Peta‐Becquerel equals 1015 Bq). This is the largest civilian noble gas release in history, exceeding the Chernobyl noble gas release by a factor of 2.5. There is strong evidence that emissions started already on 11 March 2011 at 6:00 UTC, which is immediately after the big earthquake. Xenon‐133 is neither ingested nor retained in the inhalation process and therefore of less health concern, but it is important for understanding the accident events.

L’agence météorologique autrichienne : 16 700 Peta Bq de Xe133 libérés, 2,5 fois plus que Tchernobyl, un record historique

 

Selon le Central Institution for Meteorology and Geodynamics of Austria, 16 700 Peta-Bq de Xe-133 ont été libérés dans l’environnement. C’est la plus grande libération de gaz rare de l’histoire humaine, dépassant les émanations de gaz rares de Tchernobyl d’un facteur de 2,5.

Il a commencé à fuir le 3 mars 2011 à 15:00 JST, soit immédiatement après le tremblement de terre.

Ils le rapportent ainsi :

Concernant le gaz rare radioactif Xenon‐133, les résultats indiquent une émission de 16 700 Peta‐Becquerels (1 Becquerel est une désintégration radioactive par seconde, 1 Peta‐Becquerel équivaut à 1 015 Bq). C’est la plus grande libération civile de gaz rare de l’histoire, dépassant celle de Tchernobyl d’un facteur de 2,5. On a de fortes preuves que les émissions ont commencé dès le 11 mars 2011 à 6:00 UTC, soit immédiatement après le grand séisme. Le Xenon‐133 n’est ni assimilé par la digestion, ni par la respiration, il est donc moins préoccupant mais il est important pour la compréhension des événements accidentels.

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.
