150.5 mSv/h on the second floor of reactor1

On 10/24/2012, Tepco attempted measuring the state of the reactor building of unit1.

Because they can’t send human workers, they flew a balloon to the operating room of the fifth floor.

As a result, They measured 150.5 mSv/h on the second floor.

The radiation level of each floor is like this below,

2nd floor : 150.5 mSv/h

3rd floor : 33.6 mSv/h

4th floor : 20.1 mSv/h

5th floor : 53.6 mSv/h

150.5 mSv/h on the second floor of reactor1

 

 

The balloon captured photos of the fifth floor like below,

2012年10月24日、東京電力は1号機の原子炉建屋の状況調査を試みました。作業員を送り込めないので、5階オペレーティングフロアまでバルーンを飛ばしました。そして、建屋の2階で毎時150.5 mSvを計測しました。各階の放射線量は次の通りです。

2階:毎時150.5 mSv
3階:毎時33.6 mSv
4階:毎時20.1 mSv
5階:毎時53.6 mSv

バルーンにより5階の写真撮影も行われました。

150.5 mSv/ora al secondo piano del reattore 1
Il 24/10/2012 la Tepco ha tentato di misurare lo stato dell’edificio che ospita il reattore dell’unità 1.
Dal momento che non possono mandare operatori umani hanno gonfiato un pallone nella sala operativa del quinto piano.
Come risultato sono stati misurati 150.5 mSv/ora al secondo piano.

Il livello radioattivo in ogni piano è il seguente:
2° piano: 150.5 mSv/ora
3° piano: 33.6 mSv/ora
4° piano: 20.1 mSv/ora
5° piano: 53.6 mSv/ora

Il pallone ha catturato le seguenti foto del 5° piano:

150,5 mSv/h au 2e étage du réacteur 1

Le 24 octobre 2012, Tepco a tenté de relever l’état du bâtiment du réacteur 1.

Parce qu’ils ne peuvent pas y envoyer d’ouvriers humains, ils ont fait voler un ballon jusqu’à la salle d’opérations du cinquième étage.

Ils ont relevé 150,5 mSv/h au deuxième.

Les niveaux de radioactivité de chaque étage sont les suivants :

2e étage : 150.5 mSv/h
3e étage : 33.6 mSv/h
4e étage : 20.1 mSv/h
5e étage : 53.6 mSv/h

150,5 mSv/h au 2e étage du réacteur 1

Le ballon a pris des photos du 5e :

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.
