[Hypothesis] Why doesn’t Cs-134 decrease endlessly in seawater of Fukushima nuclear plant port?

(Before It's News)

Tepco releases the data about radioactivity density (I-131, Cs-134, Cs-137) of the seawater around Fukushima nuclear plant port on the daily basis.

However, they miss the data several times a month. The reason is not announced.

They miss the data in the format below,

・No Cs-134 data, no Cs-137 data

・No Cs-134 data but Cs-137

Strangely, they never miss the data in the format below

・No Cs-137 but Cs-134

When they miss data, they miss neither of Cs-134 nor Cs-137, or only Cs-134, but they never miss only Cs-137 but Cs-134.

They graph below is the radiation readings of the seawater at reactor4 screen (Outside of the silt fence) as an example.

Also, Cs-134/137 ratio is endlessly stable. The half life of Cs-134 is 2.0652 years. However, it’s all stable at least through these 3 months.

On this post, Fukushima Diary suggests the possibility that Tepco covers up the Cs-134 readings when it is bigger than Cs-137.

If Cs-134 reading is bigger than Cs-137, it can have us suspect the possible fission.
