Ag-110m detected from gas sample of reactor1 and 3, “The boiling point is 2,164℃”

According to Tepco, radioactive silver, Ag-110m was detected from air sample of the PCV of reactor1 and 3.

From late April to mid May in 2013, Tepco analyzed the PCV gas of reactor1 ~ 3. The samples are the concentrated water of the gas and the air filters.

As a result, they measured 0.92 Bq/m3 of Ag-110m from the particulates filter of reactor1 and 1,000,000 Bq/m3 of Ag-110m from the concentrated water of reactor3.

The boiling point of Ag-110m is 2,164℃, half-life is 252 days.

As to this measurement, Tepco comment volatility of Ag-110m is big for silver iodide, it’s detected even from the environment.

Credibility. This is what Japanese government lost.

De l’argent 110m relevé dans le gaz des réacteurs 1 et 3 : Il vaporise à 2 164 °C

 

Selon Tepco, de l’argent radioactif, Ag-110m, a été relevé dans un échantillon d’air des PCV (enceintes de confinement primaire) des réacteurs 1 et 3.

Entre fin avril et mi-mai, Tepco a analysé les gaz des PCV des réacteurs 1 et 3. L’échantillon est constitué par leur eau et les filtres à air.
Ils ont ainsi relevé 0,92 Bq/m³ d’Ag-110m dans les particules des filtres du réacteur 1 et 1 000 000 Bq/m³ d’Ag-110m dans les eaux de condensation du réacteur 3.
Le point de vaporisation de l’Ag-110m est à 2 164°C, sa demie-vie est de 252 jours.
Sur ces relevés, Tepco déclare que la volatilité de l’Ag-110m est grande pour l’iodure d’argent, on en relève même dans l’environnement.

La crédibilité. C’est ce que le gouvernement japonais a perdu.

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.
