USA, Canada as well as eastend of Siberia, west Alaska are already contaminated heavily as below. Unless we take measures now, whole part of northern hemisphere are at great risk. This is not a SF.. but a real threat to humans Prev: Hello reply edit delete 15 CommentsChronological Reverse Threaded delete replyengineerpoet wrote on May 1 A Bequerel is one radioactive decay per second. 200 Bq/kg sounds like a lot, but it isn't; some granites have over 1500 Bq/kg of potassium-40 alone. If the wind is blowing to the east, this stuff will fall into the Pacific; for all intents and purposes, it will vanish. Cs-137 and Sr-90 have half-lives of about 30 years and will disappear all by themselves. This appears to be nothing to worry about. I would be more concerned about conventional air pollution from the burning. edit delete replymercedo wrote on May 1 engineerpoet said A Bequerel is one radioactive decay per second. 200 Bq/kg sounds like a lot, but it isn't; some granites have over 1500 Bq/kg of potassium-40 alone.

It reduces the disposal problem by 97%, and makes the material inert. All you'd have to do is sink the ash in the deep ocean and all the radioactives would decay before the water returns to the surface. caesium will be evapolated in around 670 Celsius I'm assuming that the incinerators will have scrubbers, so most of it will be captured. we humans breathe them That depends on the winds. If it's carried to the east, it'll mostly fall into the ocean. US west coast is contaminated To a trivial extent. We only know this because 1.Cs-137 does not occur naturally 2.Cs-137's decay energy is unique 3.This allows extraordinarily small amounts to be detected. I'd worry more about chemical contaminants from spilled oil and things. The US Coast Guard just sank a derelict Japanese ship that was washed out of a ship-breaking yard and drifted all the way to Alaska. There were concerns of fuel on board; how much more is out there, in packages too small to make the news? Trivial amounts of radioactives are nothing compared to the normal background. Worrying about them is a waste of time and a distraction from real hazards. edit delete replymercedo wrote on May 2 Our land is tiny yet densely populated..that's good if it were stored securely in a safest place, but few believes the burnt ashes will be stored securely and separately from humans for nearly 30 years Japanese made 54 nuclear power reactor but don't know how to discard the reactor after its use, so although all must have been abandoned in ten years some keep on being used for more than 25 years.. I mean they Japanese lack vision I don't think they can deal with well such a very sensitive material as heavily radioactive waste In a sense we can say they were waiting for a natural disaster to stop the operation of reactor economically. USA is far away from here so the damage must be much less than that in East Japan, but here in West Japan we have to defend ourselves because Fukushima is just next to us. Fukushima already emitted 168 times more radiation than the atomic bomb exploded in Hiroshima and 5 times more than that in Chernobyl nuclear disaster and still radiation leakage never stops delete replyrobi2106 wrote on May 2 Despite the disaster, I still don't understand Japan's efforts to ditch nuclear power. It is still massively efficient. Why not move to the liquid thorium reactor plan that will solve many of these issues highlighted by the Fukushima disaster? edit delete replymercedo wrote on May 2, edited on May 2 robi2106 said Despite the disaster, I still don't understand Japan's efforts to ditch nuclear power.

Now all 54 reactors are temporarily out of service while stress test is on, our progress in society and scientific academy is now stampede All our nationals especially eastern people are suffered from more or less radiation People can't think logical matters properly once their brains are affected by radiation We call it radioactive brains delete replyengineerpoet wrote on May 2 mercedo said All our nationals especially eastern people are suffered from more or less radiation People can't think logical matters properly once their brains are affected by radiation We call it radioactive brains Radiation, or stress hormones from all the stuff on the news and the hardships needed to save electricity... or the way electricity has to be generated when nuclear power isn't available? It's estimated that several hundred people died as a result of the Three Mile Island meltdown. Radiation didn't hurt anybody. What hurt them was all the additional coal that was burned, leading to worse air pollution. Japan is burning a lot more fossil fuel and spending a lot of money to get it. That has to hurt. edit delete replymercedo wrote on May 3 engineerpoet said Radiation didn't hurt anybody In the case of Fukushima, radiation hurt anyone who is vulnerable to radiation which counts about 10 per cent of all population. Women, elderly and infants are affected more severely. On the other hand 11 per cent are believed to have resistance on radiation, so effect of radiation varies up to individuals. We believe radiation caused by this disaster is 168 times more than Hiroshima and 5 times more than Chernobyl so now many people start having various health problems. We will encounter severe diseases as heart attack, stroke, leukemia, and cancer in the coming years. Yes in the 1960s, there were several areas whose air is very contaminated. But because of the effort we had made the problem of air pollution has been greatly reduced by multiple filtration, etc. delete replyengineerpoet wrote on May 3 mercedo said radiation hurt anyone who is vulnerable to radiation which counts about 10 per cent of all population. Women, elderly and infants are affected more severely. Can you provide a reference in English for this? As I've mentioned elsewhere, people Ramsar in Iran get an AVERAGE of 260 mSv/year and don't have obvious ill effects. Also, most effects of low-dose radiation (such as cancer) are delayed by years; it is simply impossible for them to have appeared already. Stress hormones, buildings too cold or too hot, and other non-radiation side effects would take effect immediately. I don't know any Japanese, but I'll refer you to the English definition of parsimony, which is a virtue in scientific explanations. The "radiation did it" claim is not parsimonious. delete replyengineerpoet wrote on May 2 robi2106 said I still don't understand Japan's efforts to ditch nuclear power. I found a news item which mentioned that Japan's oil imports had jumped by about 113,000 barrels per day to feed thermal powerplants (I'm sure it's greater now). That would cost about $11 million per day ($4 billion per year), plus extra imports of coal and LNG and the cost and discomfort of conservation measures. Next Big Future had a post recently about a couple of plants which had passed their checkouts and were ready for restart, waiting only for approval of the prefecture. If the plants are not owned by TEPCO, I'm not sure why they haven't been given the go-ahead yet; it appears that all of them are being made to pay for TEPCO's sins, and Japan as a whole. delete replymorosoph wrote on May 2 I'm glad that you're still around, Eiko. I understand that whatever the risks on the ground, this failure has had a psychological impact on the Japanese population, and I can understand that nuclear failures would be exceptionally distressing to the Japanese. If engineerpoet is right, at least you shouldn't have too many physical problems to deal with, but I am very sympathetic to the distress that must be felt after the Fukushima disaster. It must be difficult to keep a level head. I hope that you're going strong, and that life is treating you well. My best, Tim. edit delete replymercedo wrote on May 3 Hi, Tim... Just take a close look at this map! About one- third of whole Japan is severely contaminated by very strong radiation. A couple of days ago in Tokyo 50 people found dead in bed in the morning on the same day.. Drinking water in Tokyo often counts 2 or 3 Bq per litre. I think the fall of our society is just a matter of time. delete replymorosoph wrote on May 3 Stay sane and safe. I expect that there will be a statistically significant, but small increase in the number of deaths, birth mutations, and such like. But it will be a small fraction of the population. A mother whose baby is mutated will think otherwise, but I expect that life will go on much as before for most people. That said, the nuclear meltdowns are a distressing thing to happen in any culture, and there is always likely to be that feeling of being punished for 'playing God' by manipulating fundamental forces of nature. delete replyengineerpoet wrote on May 3 mercedo said Just take a close look at this map! There's no valid hyperlink or URL there. I tried to find a map last night, but I didn't come up with anything more recent than last June or so. If you have a good one (and a translation of any Japanese on it), I'd love to see it. delete replyengineerpoet wrote on May 3 mercedo said Drinking water in Tokyo often counts 2 or 3 Bq per litre. Note that a bequerel is one decay per second. It is a VERY small amount of radioactivity. The radioactivity from natural uranium in seawater is 33 mBq/liter. 14C is another 5 mBq/liter; I'm assuming that's largely due to dissolved carbonate and bicarbonate ions. You're concerned about 3 Bq/l, but Germany had milk measuring 20 kBq/l after Chernobyl. There would have been rises in drinking water too. Germany did not have the sort of health issues you're claiming here, despite what appears to have been much worse contamination. This suggests that any problem actually has some other cause. Radiation could be a convenient distraction from something else that's going on. Have you ever considered that? Remember, TEPCO managed to deny that there was anything deficient about their designs or practices. Who else could be doing that today? Something to think about. Radiation is worrisome because it's invisible and you can't do anything about it. However, if people are blaming harmless levels of radiation for problems caused by a real health threat, you're harming yourself twice: you're stressing out over the radiation, and not protecting yourself from the real problem. I'm thinking about the bubonic plague and Yellow Fever. People didn't understand that they were transmitted by flea and mosquito bites, so they failed to do things that could have protected them. This could be another example. The first thing is to de-stress. Stress will kill you even if nothing else is wrong. audio reply video replyAdd a Comment For: Add a comment to this blog entry, for everyone Send mercedo a personal message Subject: - Quote original message neim0 engineerpoet allenzadr printf morosoph Viewing History Viewed 63 times by 17 people, latest at 11:00 AMViewing HistoryView This Page as Another User mercedo Eiko Onoda Fukuoka , Japan Upgrade My Account Customize My Site Promote My Site My Contacts (21) My Groups (7) Shop Online in the Marketplace · Philippines Marketplace · Indonesia Marketplace · Open a Free Shop © 2012 Multiply · English · About · Blog · Terms · Privacy · Corporate · Advertise · API · Help · Sitemap Template design - Copyright © 2005 Sam Royama All rights reserved. placeholder Share
