I tried to seed this, but it could not get past the in inspecting link part, so after two attempts and waiting 15 minutes I assumed it was not going to do so, even though the page is not in Japanese, lol.
Unit 2 water 10 times more radioactive than Unit 1 — 47,000,000 becquerels per liter in turbine room basement
The significance of this is that the radiation level in Unit 1 already precludes virtually all human activity there and robots are having to be used, or even invented, to be able to do what is required. In addition, recent research elsewhere has shown that modern electronics are roughly 10 times more vulnerable to radiation than was previously thought. This is because they are now scaled down to a point where a transistor function is composed of a few thousand atoms. This makes them more vulnerable to some atomic changes than when they were composed of a much higher number of atoms. As a result, measuring apparatus and most things being used break down much more rapidly than expected
This water problem seems likely to get worse for two reasons. Firstly more water is being added from rain and ground seepage into the basements. Secondly there is a high probability that the basements contain at least some melted fuel that melted through the containment vessels and thought the floor to the basement (I've even seen it said that they do not know where the meltdown of N°2 actually is). The water is absorbing the radiation as that fuel is cooled. As the water is not being replaced, then the amount of radiation it contains is forced to rise.
Another aspect is coming to light, given at http://enenews.com/quite-extremely-radioactive-sample-tokyo-air-filter-150-times-uranium-expected-fukushima-busby-video
The videos are also useful in seeing what tool-aided capacity they have to analyse things nowadays, quite remarkable. It seems that Uranium-235 has been detected. This has a half life of a little over 700million years, so can be viewed as permanent. In spite of my following the Fukushima event in detail ever since it started, I have still yet to see any detail of ALL the radioactive isotopes emitted and their approximate amount. Information is given in trickles over time and is usually restricted to isotopes with a half life of 2 years or less.
What is becoming clearer and clearer is that the contamination is much worse and more widespread than we have been led to believe and certainly millions of Japanese, including the 13 million living in Tokyo, are being kept in the dark. Thus they are being prevented from taking actions to preserve their health by not being given the full information. Personally, that seems a crime against humanity to me.
