I think their most important point, as summarized by the article above, is as follows:<br /><br />"The new analysis also claims that the spent fuel being stored in the unit 4 pool emitted copious quantities of caesium-137. Japanese officials have maintained that virtually no radioactivity leaked from the pool. Yet Stohl's model clearly shows that dousing the pool with water caused the plant's caesium-137 emissions to drop markedly (see 'Radiation crisis'). The finding implies that much of the fallout could have been prevented by flooding the pool earlier."<br /><br />However, if you read the paper, you'll see that the authors spent remarkably little effort on the causality here. They seemed satisfied that because A and B happened at roughly the same time, A must have caused B. Meanwhile, those of us who remember those harrowing days saw how fluid and dynamic the situation was, but the authors devote zero ink to considering other possible factors.<br /><br />In the end, I think they may very well be right, but they do themselves a disservice for not tackling this issue more thoroughly. <br /><br />(In any event, this is why papers are submitted for discussion prior to being published! I trust that they will rectify some of this prior to publication.)Yosakunoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-77986548009897543882011-10-26T20:48:54.924-07:002011-10-26T20:48:54.924-07:00The report said 78% of the cesium went into the oc...The report said 78% of the cesium went into the ocean. I'm not comforted by that. This means more cesium in fish, algae, and entering the global ocean currents which can then push ashore onto sandy beaches all over the world.<br /><br />The ocean is also involved in the rain cycle, so that could mean more radioactive rain.<br /><br />Don't believe the "dilution is the solution" propaganda.<br /><br />This really is an environmental nightmare.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-39965170181864344632011-10-26T08:29:41.309-07:002011-10-26T08:29:41.309-07:00Exactly as Anonymous 4:15 says, this is far from o...Exactly as Anonymous 4:15 says, this is far from over. Many report it as though it is done and over with. Even my friends, family and coworkers back in Japan talk as though it is over. It is not as the fuel from the reactor cores are open to the air in the ground and also the spent fuel rods are in an unconfirmed state. Also, so much fuel has been spread around and now there are reports of reactors 5 and 6 being in danger.kintamannoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-42960483068653827202011-10-26T07:31:18.518-07:002011-10-26T07:31:18.518-07:00Fukushima still continues to emitt radionuclide fa...Fukushima still continues to emitt radionuclide fallouts. <br />Let's please be careful not to speak or write about Fukushima as if the releases were over.<br />They are not, the crisis is not over, the emissions are still ongoing, via air, vapors or water. <br />Sentences such as "...Reactor 4 Spent Fuel Pool emitted..." or "...The disaster at the Fukushima Daiichi nuclear plant in March released..." make it seems like the emissions are over.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-47460467700930846942011-10-26T04:15:47.585-07:002011-10-26T04:15:47.585-07:00This explains the amount of cesium being discovere...This explains the amount of cesium being discovered. Read following from site, Story Behind the Story, Dr. A.T. Ott. <br /><br />There are about seven isotopes of xenon that are radioactive and would be released in such an incident, with atomic masses of 133, 135, 137, and 138, along with three isomers, 131m, 133m, and 135m. With the exception of the isomers, each of these xenon atoms will decay into cesium and some into other elements past cesium. There is also krypton but its radioactivity and decay products are of less concern. Xenon itself is not particularly dangerous. It is a noble gas and is not concentrated in the body. Cesium is more of a concern. Here are the seven decay sequences: Xenon-131m will decay to stable xenon-131.<br />Xenon-133m will decay to radioactive xenon-133.<br />Xenon-133 will decay to stable cesium-133.<br />Xenon-135m will decay to radioactive xenon-135.<br />Xenon-135 will decay to very mildly radioactive cesium-135.<br />Xenon-137 will decay to radioactive cesium-137.<br />Xenon-138 will decay to radioactive cesium-138 and then quickly to stable barium-138. Of all of these, the decay of xenon-137 to cesium-137 is probably responsible for the most risk, but xenon-137 decays so quickly that the mobility of cesium-137 is limited. I do not think this poses much risk because it can’t get far. "<br /><br /><br />I.E.

Better yet, send them to work in the nuclear reactors first hand. <br /><br />Those responsible:<br /><br />- TEPCO CEO who recently retired to escape.<br />- TEPCO top executives and upper management.<br />- Japanese government top officials.<br />- So called "experts" who misinformed so many people about the dangers.<br />- Media top officials and even announcers who lied.<br />- Whoever made the order which prevented the TEPCO people on site from using Sea Water right away when they knew what had transpired. This is what contributed in a large way to the disastrous releases of radionuclide materials.<br /><br />Do NOT let these criminals get away. Put these people on site at Fukushima Daiichi. Why should they be allowed to escape the results of their decisions and crimes?kintamannoreply@blogger.com
