High level of Cs-134/137 detected on the top of reactor3 again / Spread by the wind

Fukushima Diary reported Cesium-134/137 level jumped up 10~1,000 times much as average on the top of reactor3 on 8/23/2013. [URL]

 

On 8/29/2013, higher level of Cs-134/137 was measured in the dust of the top of reactor3. The top floor (Operation floor) of reactor3 was already covered with the antiscattering agent. It is unlikely that the Cs-134/137 level in the dust was picked up due to the debris removal on the building.

Cs-134 density was 8.1×10^3 Bq/m3, Cs-137 density was 1.7×10^4 Bq/m3.

The wind blew from the east at this time (2m/sec), and the significant level of Cs-134/137 was also measured in two locations of downwind.

Cs-134 : 1.1 ~ 3.1 Bq/m3

Cs-137 : 2.6 ~ 9.1 Bq/m3

 

There is a possibility that the radiation level of the gas from reactor3 is picking up for some reason, and it’s spreading by the wind.

Encore une radioactivité forte en césium 134/137 au sommet du réacteur 3 / Éparpillée par le vent

 

Le 23 août dernier, le Fukushima Diary a publié qu’au sommet du réacteur 3 le niveau en Cs-134/137 était monté à entre 10 et 1 000 fois la moyenne. [Lien]

Le 29 août 2013, une radioactivité encore plus forte du Cs-134/137 a été relevée dans les poussières du sommet du réacteur 3. Le dernier étage du réacteur 3 (étage opérationnel) est pourtant recouvert d’un agent fixateur. Il est très peu probable que cette radioactivité en Cs-134/137 des poussières soit due au retrait des gravas du bâtiment.
La radioactivité en Cs-134 était à 8 100 Bq/m³, celle du Cs 137 à 17 000 Bq/m³.
Le vent soufflait alors de l’Est vers l’Ouest (2 m/sec = 7,2 km/h) et une radioactivité importante en Cs 134/137 a aussi été relevée en deux endroits sous le vent.
Cs-134 : 1,1 ~ 3,1 Bq/m³
Cs-137 : 2,6 ~ 9,1 Bq/m³

Il est possible que le niveau de radioactivité des gaz du réacteur 3 soit en train d’augmenter et ça se disperse avec le vent.

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.
