I don’t relish being negative all the time. I still hope to find positive aspects of Fukushima. The remnants of Hurricane Isaac bringing clean air and rain to parts of the US, for instance. (But it appears the remnants of Isaac have picked up some radiation on the back side of the storm, so it’s a mixed bag.) Iodine-131 levels dropped in Gunma prefecture sewage sludge a couple weeks ago, so I thought it might be a trend.
Gunma levels spiked in June, but came down and now they are roughly at the same levels they were in May 2011, after the reactor explosions. Kawasaki spiked later in June, dropped, and then went up again in July, before dropping again. (Note that the iodine-131 deposition depends on wind direction and rainfall, and these are widely separated locations.)
But, oh, Yamanishi prefecture iodine is way up. And Chiba prefecture is holding it own. It’s not a trend, it’s just the vagaries of wind and rain.
Iodine releases are important, not just from the thyroid diseases that result from exposure to this radionuclide, but as an indicator of fission and re-criticality. The table below indicates the radionuclides from a criticality accident in the Idaho chemical processing plant in 1959. These are the same kind of isotopes that we can expect to be released from a Fukushima re-criticality. Dangerous isotopes such as cerium-143, barium-140, ruthenium-103, and uranium-235 are to be found. Hey wait, these are the same kind of isotopes that Potrblog found in an analysis of Missouri beef.
Finding iodine also means that the underground coriums at Fuku are not hardening and cooling off, but heating up and continuing to be on the move, steaming whenever they encounter groundwater.
Observe the spike that occurred in Chiba in late October through November. There was also a spike in Yamanashi in November. There was a report of iodine-131 in central Europe last Nov. 11. This had been going on for two weeks. The international gangsters at the IAEA not only said that this was safe, but they blamed the release on a Hungarian lab. But I ran a HYSPLIT backwards trajectory on atmospheric winds in that time frame (18,000 ft.) and the trajectory corresponds to a Fuku release of iodine around Oct. 24. This plume, which was much wider than the trajectory shows, entered the US in the Pacific northwest, moved through southern Canada, and dived down into the midwest and eastern seaboard, before crossing the Atlantic and entering Europe. This was around the time my thyroid was bulging out of my neck. Yes, this stuff went three-quarters the way around the earth and it was still a problem. There was also a xenon release from reactor 2 at this time, Chris Busby analyzed it and said there was either fission 50 hours before the measurement (no later than Oct. 31 2011) or an explosive criticality 60 hours before. This turns out be be near the time frame of the Fuku release deduced from HYSPLIT. This youtube video shows ground shaking in the early morning hours of Oct. 22, and another video shows abnormal smoke from reactor 2 starting 15 hours later.
There was another detection of iodine-131 on Jan. 16-23 in the northern tip of Scandinavia, but the IAEA idiotically blamed the Hungarian lab for that too, even though it was something like 1,000 miles away.
