Sounds a bit bonkers to me to be honest. Of course all the money is going to be coming from the govt as TEPCO is bust anyway.James Annanhttps://www.blogger.com/profile/04318741813895533700noreply@blogger.comtag:blogger.com,1999:blog-9959776.post-45066603435621651212011-09-06T14:19:42.712+01:002011-09-06T14:19:42.712+01:00Irn, I don't think there's too much planne...Irn, I don't think there's too much planned yet - the politicians have more important things to do like jockeying for a better shot at the PM's seat next election time.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9959776.post-53000373632502110382011-09-03T10:26:06.166+01:002011-09-03T10:26:06.166+01:00As far as you know, are there any stories in the m...As far as you know, are there any stories in the media dealing with the government's plans for providing for Japanese who lost their means of livelihood because of the nuclear disaster? For instance, I know that at least one onsen town in Fukushima has lost most of its income since tourists from other parts of Japan have no interest in a place they view as being tainted. Ryokans are closing, and the people who live in town and worked in those ryokans are now without jobs. Also, small mom and pop businesses are suffering because of the lack of customers. Many of these citizens only know one trade and lack the resources to move and the schooling to obtain another job.lrnhttps://www.blogger.com/profile/02537129220340172426noreply@blogger.comtag:blogger.com,1999:blog-9959776.post-91495755737648140372011-09-02T07:01:50.442+01:002011-09-02T07:01:50.442+01:00Well for better or worse we place greater safety r...<i>Well for better or worse we place greater safety requirements on nuclear reactors.

Lots of people were lost actually returning home, or taking time to collect belongings. If they'd known there was a large 1000 year tsunami overdue for the area they might have made different choices and still be alive today. Who was supposed to inform these people is a question that no one seems to be asking.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9959776.post-30251217068688152202011-09-01T17:35:05.492+01:002011-09-01T17:35:05.492+01:00Many thanks for your answers!Many thanks for your answers!Jesús R.https://www.blogger.com/profile/08623637876422608968noreply@blogger.comtag:blogger.com,1999:blog-9959776.post-77308757838461922372011-09-01T08:17:10.396+01:002011-09-01T08:17:10.396+01:00Well for better or worse we place greater safety r...Well for better or worse we place greater safety requirements on nuclear reactors.

It's particularly galling to see the LDP avoiding any responsibility for the mess they helped set-up. Unfortunately Japanese society expects the current people in charge of organisations that cause problems to resign to "take responsibility" - this act wiping the slate clean, and avoiding any soul-searching for insights as to why the problems occurred in the first place.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9959776.post-43182275191057491542011-09-01T05:02:37.407+01:002011-09-01T05:02:37.407+01:00Yea-mon has beaten me to it.

No farmers or farming organizations seem to have queried the use of rice straw either.<br /><br />The Farm Ministry was later found to have also forgotten about how compost was made - leading to contaminated compost entering the market.<br /><br />* TEPCO had recently concluded that a 10 metre tsunami could possibly hit Fukushima - but there seemed no urgency on this point (how could they know what was soon to happen?). To be honest, this is more a systemic failure - as TEPCO was asked by the nuclear regulator, NISA, to investigate the matter. Such things should be done by regulators, and more specifically whatever branch of the bureaucracy is concerned with preventing disasters. To be honest, if there was a more coherent approach to disaster in Japan perhaps the death toll in Tohoku would have been much lower, after all - if TEPCO could conclude a large tsunami would hit their plant, perhaps a Disaster Prevention Agency could have reached such a conclusion earlier and warned municipalities to guard against such an event.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9959776.post-82199677380152309202011-08-31T22:58:21.315+01:002011-08-31T22:58:21.315+01:00May I ask in what specific points Govt and Tepco h...May I ask in what specific points Govt and Tepco has proven to be incompetent and/or dishonest?

Also, I hadn't noticed this:<br /><br />"An NRC task force set up in the aftermath of the Japan crisis urged a shift in the NRC's safety regime that would force plants to plan for catastrophes far worse than design specifications allowed for, as well as require that companies assess seismic and flooding hazards at plants every 10 years."<br /><br />The first one in particular is a good idea, but as a reasonable application of it would mean the end for some existing plants I expect it won't be implemented.<br /><br />Re the general issue of radiation in the environment, I'm a lot less worried about it than about the increasing load of chemicals we're all carrying around. OTOH, that doesn't make the radiation benign.<br /><br />Probably, though, the largest health issue is with people who, thanks to the gov't/TEPCO collaboration that just seems to keep on giving, lingered in contaminated areas in the days immediately following the containment breaches.Steve Bloomhttps://www.blogger.com/profile/12943109973917998380noreply@blogger.comtag:blogger.com,1999:blog-9959776.post-18893738329419937582011-08-30T07:05:49.441+01:002011-08-30T07:05:49.441+01:00James,

But (when talking about the habitability of affected areas and whether children can go to school there) the JGovt is primarily talking about a per-year dose in the context of an ongoing exposure to ambient conditions, which seems a fairly straightforward comparison to background radiation in other regions.James Annanhttps://www.blogger.com/profile/04318741813895533700noreply@blogger.comtag:blogger.com,1999:blog-9959776.post-61518542260056530352011-08-29T23:59:52.595+01:002011-08-29T23:59:52.595+01:00> Cornwall

Most of what's known about how it behaves is recent, based mostly on industry accidents and animal studies.<br /><br />Per a one-cow dissection study (I quoted at Stoat's) the standard for cesium assumes it's evenly distributed throughout the body -- but the dissection identified cesium concentrated in some tissues far more than others.
