Tepco concealing the analysis data for Plutonium because of “the bad weather”

On 3/21/2013, Tepco released the marine soil analysis data about Pu-238/239/240, but they didn’t show the readings of the soil taken from the south discharge channel of Fukushima plant.

The sample was dry soil. The analyzed samples were taken 6 months ago, last September.

Tepco states they couldn’t take samples due to the “bad weather”, but according to Japanese Meteorological Agency, there were 22 sunny days in September. There were only 3 rainy days.

Tepco also measured (2.2±0.29)×10-1 Bq/Kg of Pu-239/240 from dry soil of North of reactor5, 6  discharge channel.

They evaluated like this below, but unfortunately it’s mentioning the wrong date of “July 19, 2012”.

Given that the density level of Pu-239+Pu-240 detected on July 19, 2012, is the same as the past density measurements (1.7×10-1~5.6×10-1 Bq/Kg) conducted along the seacoasts of 1F and 2F, it cannot be stated with absolute certainty that the presence of these particles is due to the accident.

Tepco cache les données d’analyse du plutonium “à cause du mauvais temps”


Le 21 mars 2013, Tepco a publié les données d’analyse des fonds marins sur les Pu 238/239/240 mais ils n’y ont pas mis les relevés des sols pris au déversoir Sud de la centrale de Fukushima.
L’échantillon est du sol sec. Les échantillons analysés avaient été pris il y a 6 mois, en septembre dernier.
Tepco affirme qu’ils ne pouvaient pas prendre d’échantillon “à cause du mauvais temps” mais selon l’Agence météorologique japonaise, il y a eu 22 jours ensoleillés en septembre. Il n’y a eu que 3 jours pluvieux.

Tepco a aussi relevé (0,22 ±0.29) Bq/kg de Pu-239/240 dans du sol sec du déversoir nord des réacteurs 5 et 6.
Ils l’ont évalué ainsi mais malheureusement c’est à la fausse date du “19 juillet 2012” :

Attendu que la concentration en Pu 239 + Pu 240 détectée le 19 juillet 2012, est la même que lors des précédents relevés (0,17 à 0,56 Bq/kg) le long des rivages de F1 et F2, on ne peut affirmer de façon absolue que la présence de ces particules soit due à l’accident.

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.
