#Fukushima I Nuke Plant: Radioactive Materials at Reactor 2 Silt Fence Rising, Again

Radioactive iodine-131 shot up inside the silt fence in front of the water intake for the Reactor 2. Radioactive cesium (134 and 137) continues to rise OUTSIDE the silt fence for the Reactor 4, and the water levels at the trenches from the Reactors 2 and 3 continue to rise.

All is not well at Fukushima I Nuke Plant; it never has been since the earthquake.

From TEPCO's press release (English) on May 29:

Unit 2 inside the silt fence, for the sample taken on May 28:

Iodine-131: 24,000 becquerels/liter
Cesium-134: 4,100 becquerels/liter
Cesium-137: 4,300 becquerels/liter

The same nuclides from the sample taken on May 27 (and announced on May 28):

Iodine-131: 5,200 becquerels/liter
Cesium-134: 1,600 becquerels/liter
Cesium-137: 1,700 becquerels/liter

#Fukushima I Nuke Plant: Higher Radioactive Materials Outside the Silt Fence of Reactor 4 Than Inside?

Some funny numbers for the Reactor 4's nuclide analysis at the silt fence at the water intake.

TEPCO's press release on May 28 on the samples taken on May 27 shows the water OUTSIDE the silt fence for the Reactor 4 water intake had a much higher radioactive material concentration than the water inside the silt fence.

This wasn't the case at all on May 25 samples whose level of radioactive materials was higher INSIDE the silt fence, as you would expect. Hmmm. The silt fence for the Reactor 4 water intake is not working? But why would the outside be more radioactive than the inside?
