The video below explains - somewhat - how this ice wall experiment will be built and work, or rather not work.
Quote:The prime minister, Shinzo Abe, said he understood the growing concern at home and overseas about the state of the plant but said his government was now "taking the lead" to solve the problem. "To do that we are resolutely implementing drastic measures."
As I've mentioned twice before, so-called dilution (dispersion) is a smoke screen. There is zero relevance to how diluted or dispersed the radiation is. Dilution applies when talking about chemical reactions, not nuclear disintegrations. Maybe they talk about dilution as a way to assuage the public because it is something the public can grasp - even though it has no bearing on the effects of radiation.
Nuclear disintegrations cause harm by changing the physical chemistry of the cells without changing the radioactive material's ability to do it again and again, millions or billions of times. There is no chemical reaction, thus the radioactive material isn't "tied down" to one reaction.
This latest chart uses the same failed concept that the Potassium-40 radiation in a banana is the same as the high energy radiation from Cesium-137 and from high energy Strontium. Is was pointed out before, Cesium is 12.4 MILLION times more dangerous than the Potassium-40. IOW, the charts are preposterously misleading.
the chart refers to millisieverts when it is Curies that make the difference.
You could build a treehouse in the middle of a banana tree farm and spend your entire life there eating bananas every day three times a day and never be affected by the radiation from the Potassium-40.
But if there were 2 grams of radioactive Cesium-137 within an acre, the land would be uninhabitable because you'd be exposed to 176 Curies of radiation.
You might be tempted to look at the chart and assume that 176 Curies is the same as a 176 millisieverts, IT IS NOT!!
There are 37 BILLION bequerels to one Curie. To convert the Curie into sieverts it requires a computation of the bequerels, times the amount of time exposed, times the energy signature of the particular radioactive isotope.
The bottom line is this, if you put 100 or a 1,000 people in the banana field contaminiated with 2 grams of Cesium-137 to live all of them would be dead within a year. Most would die within a few weeks.
People just don't grasp how serious this is.
Pray for me.
