Tepco is running the water circulation system to purify. However, it only filters gamme nuclide, beta ones remain the same.
They release only the data of the gross amount of beta nuclides. However, the data of tritium is separated for some reason.
Though some of the data is missing, it was comparable to the total amount of gamma nuclides in the process to enter desalinization apparatus.
The results are like these below. Tritium is contained over 34 times the amount of total gamma nuclides.
Also, the tritium data from the sample taken on 3/20/2012 was concealed in the data published on 3/26/2012. [Link]
They must have obtained the data but did not publish until one month later after the measurement.
The desalinization apparatus is located after cesium filters. The total gamma nuclide might be more than 1/34 times of tritium before cesium filter section, but because the tritium data is missing in that process, it is impossible to compare the amount of tritium and gamma nuclides.
