Ministry of Defense detected Xe-133 from the atmosphere of Aichi offshore “halflife is 5 days”

 

On 2/13/2013, Ministry of Defense conducted aircraft monitoring of radioactive material for N. Korea’s nuclear test based on the forecast of WSPEEDI-Ⅱ.

(cf, [Surrealism] MOE reinforces radiation monitoring for the nuclear test of N. Korea [URL 1])

On 2/21/2013, MEXT announced they measured Xe-133 from the atmosphere of 300m altitude offshore Aichi. The amount was 1.9 mBq/m3.

They state the connection with N. Korean nuclear test is not known.
Xe-133 is a fission product, daughter of Uranium 235, half life time is 5.2 days.
MEXT did not mention the possibility that the Xe-133 came from Fukushima.

Le Ministère de la Défense a détecté du Xe-133 dans l’atmosphère au large de Aichi “demie-vie de 5 jours”

Le 13 février 2013, le Ministère de la Défense a mené une mission aérienne de surveillance de la radioactivité après l’essai nucléaire de la Corée du N. basée sur les prédictions du WSPEEDI-Ⅱ.

(cf. [Surréalisme] Le MOE renforce la surveillance de la radioactivité après l’essai nucléaire de la Corée du N.)

Le 21 février 2013, le MEXT annonce qu’ils ont relevé du Xe-133 dans l’atmosphère à 300 m d’altitude au large d’Aichi. La quantité était de 1,9 mBq/m³.

Ils affirment que le lien avec l’essai nucléaire nord-coréen n’est pas établi.
Le Xe-133 est un produit de la fission, descendant de l’uranium 235, sa demie-vie est de 5,2 jours.
Le MEXT ne précise pas si le Xe-133 pourrait provenir de Fukushima.

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.
