Fukushima Casualties
There are two socio-economic casualties of the Fukushima aside from the obvious spread of radiation. First a few comments on that. It’s disingenuous to compare CT scans and X-rays to atmospheric radiation since a one time zap is completely different than having a radioactive particle lodged in your body. Once ingested each different element migrates to a specific part of the body – radioactive Iodine, for instance, goes to the thyroid – and continually and cumulatively discharges its carcinogens.
We also often find exposure compared to background radiation, as if it’s no big deal. What they don’t mention is that most background radiation is a result of nuclear testing; it’s not something people have always lived with, and, as mentioned previously, there is no safe level of exposure. All radiation causes cancer; minimal exposure causes minimal cancers, but since it’s all cumulative, every little bit increases your chances of developing the disease.
One casualty of Fukushima is globalization itself. The concept of globalization encourages manufacturers to scour the globe for the cheapest and best possible location for fabricating and/or assembling each individual part of a complex whole. This has caused a lot of grief for Toyota, which has had to stop or slow production of its vehicles in plants around the world because of the earthquake/tsunami. Sometimes a part is manufactured in only one location and if that one plant gets washed away in a giant tsunami, well everything shuts down.
Toyota also pioneered just-in-time manufacturing. Instead of producing and then storing parts in warehouses for eventual use, parts are delivered to the assembly line just minutes before they are to be used. As a result there is no leeway, if any part of the supply chain breaks down the whole edifice shuts down. It’s a very efficient method of manufacturing, but as we see subject to total breakdown when things don’t go exactly according to plan.
The other casualty is the Nuclear Renaissance, the return to the purportedly ‘green’ energy source, which has been dead in the water for decades because of a multiplicity of factors. Fukushima won’t stop China and other countries, rich and poor, from building nukes but it will certainly slow the process. It will also increase dependency on fossil fuels just when we are approaching peak oil crunch time.
As we are now seeing, in the frantic attempt to sustain the endless growth paradigm, ever more delicate, difficult and dangerously placed reserves are being developed. While BP was guilty of gross negligence in the Gulf of Mexico blowout, the proliferation of drilling around the world in those marginal areas will almost certainly result in additional catastrophic pollution events. That’s in addition to the damage done in some processes even when all goes according to plan, as in the poisoning of groundwater that results from using hydraulic fracturing in extraction of gas from shale deposits.
All in all the environment is in for some serious thrashing and trashing.

Fukushima Going Down
Excessive radiation has been found 50 kilometers from the plant, the exclusion zone, however, is only 20 k. If they expand to 40 k, 170,000 people will have to be evacuated, probably permanently. The exclusion Zone around Chernobyl is half the size of New Jersey. Moreover that excessive radiation found outside the Fukushima exclusion zone would be over the limit allowed inside the Chernobyl zone. In other words, they are being very lax about their citizens’ safety.
Previously Japan’s sacrificial plant workers were limited to 100 millisieverts of exposure. At that level, one in a thousand will develop cancer. At the new limit of 250, that proportion goes down to one in four hundred. That’s not bad odds, or wouldn’t be if it was the only toxin people were subject to in their daily lives. But add up all the nasties in water, food and air and give them a couple of decades to do their damage and the proportion goes down to 1 in 7. It wouldn’t be such a big deal if cancer was a quick and easy death, rather than the long drawn out and debilitatingly painful one that it is. However, the plant workers are being compensated; previously earning $100 to $200 per day, they are now receiving $4000 per day. Hopefully they’ll live long enough to enjoy their new found riches.
In the process of dousing the stricken reactors with large amounts of water, one thing they are doing is creating radioactive steam, evidently able to spread far and wide. They’ve also been creating contaminated water, part of which they need to store and somehow dispose of safely, another part is seeping into groundwater and a lot of it is draining into the sea.
Three hundred thirty meters from shore the water was, at last report, more than 4000 times over the limit and that number is growing every day. That seems very far from shore to be so contaminated and must entail a gusher of a leak. Radiation twice the limit has been found 40 kilometers from the shore so a massive contamination of the sea. No problem, the authorities say, the ocean will dilute it. Yes but how many mutant fish will emerge in the meantime?
Latest news is they found a crack in one of the containment vessels which might be the source of the leak, or maybe at least one source. They really don’t know for sure where it’s coming from. And it’s too dangerous to be able to spend the time, get up close and really find out why it’s leaking. It may go on for a long time. It may render a large part of the Japanese coast off limits to fishing on a permanent basis.
If a country wished to take a chance on permanently polluting its land, that would be their choice, but radiation knows no national boundaries. If Japan, one of the world’s most technologically advanced nations can’t keep it together, how can the world possibly be safe with a whole bevy of developing countries embracing nukes?
To me, nuclear power is emblematic of the idiocy and insanity of modern corporate life and its sway over government of all stripes. Nukes are now more expensive than wind. It takes five to ten years to bring one on line compared to one year for wind. There isn’t a single privately financed nuke in the entire world, because no deep pocket financial institution in its right mind would put up the money without 100% guarantees from government. There isn’t a single insurance company that will cover the full costs of a nuclear meltdown. There is still no way to permanently dispose of nuclear waste and though the radiation in spent fuel is just as dangerous as that in nuclear cores, the spent fuel is housed in tin sheds rather than the foot thick steel walls of the containment vessel for the nuclear core.
There’s no CO2 produced in a nuke, but a large amount is produced in the mining and processing of Uranium and the people who work in that area have a much greater risk of cancer than the general population.
It doesn’t make any sense and it never has, but still, even after Fukushima, there are a lot of people who’re still pushing for nukes and a lot of countries that’ll continue to pursue the ultimate disaster of nuclear power.

Tsunami Warning
I haven’t had much time to keep up with the blog lately as I’ve been working on a new book, Hitchhiker’s Guide to Enlightenment, but I had to take a little time off to comment on the earthquake, tsunami and nuclear meltdown in Japan.
It’s ironic that Japan, the country that’s suffered most from radiation has relied so heavily - 30% of its electricity - on nuclear power. It is also, of all countries, most subject to strong earthquakes. Something like 20% of all earthquakes over magnitude 6 on the Richter scale happen in Japan. As you’d expect, with that background, Japan is, relatively speaking, very well prepared for quakes. Forty story buildings in Tokyo swayed like palm trees but didn’t crumble.
However, at 9.0 that was the 4th strongest quake recorded since 1900, and the strongest in Japan in 300 years. It moved the entire country 4 meters to the east. That was not something you’d ever expect, at least not in your lifetime, so not something Japanese officials cared to plan for. But they do happen and with the consequences of nuclear meltdown so grave, even a 1000 year event should’ve been taken into account.
Moreover, with the very word tsunami derived from the Japanese, that’s also something they should’ve considered. There again, this wave was so outsized nobody there would’ve believed it could’ve ever happened. Nevertheless, when dealing with nuclear meltdown, the worst case scenario has to be part of the calculation. It’s not like when a windmill crashes and all you have to do is recycle the metal.
The government had been saying that radiation releases have been small and not dangerous, but now they are admitting spikes of unhealthy levels of radiation. One slick move made by the Japanese government was to lower standards for allowable radiation exposure when workers at the plant were getting over the maximum limit, otherwise they would’ve had to stop working. No big deal unless you’re one of the workers who might die from that exposure. More recently, they announced levels of radiation in food produced in the general area that were over allowable limits, but then said it wasn’t dangerous. Then why have a limit if there’s no harm in going over it? Some people feel there is no safe limit, that any amount is harmful.
The conventional wisdom has it that there was little radiation released at Three Mile Island and nobody died from it, in spite of the fact that cancers in the area spiked for a whole generation. It boggles the mind how the industry and their government enablers either believe their own lies or don’t care as long as there are profits to be made. After all, they have to breathe the same contaminated air as everyone.
Moreover, the industry, aligned with western governments is pushing nukes all over the world. Turkey, China, Pakistan, Vietnam, Indonesia, India, amongst several other countries, are all planning on developing nukes, so further meltdowns are inevitable. Take India for instance, it’s a great country with a lot going for it, but they haven’t been able to figure out how to provide toilets for more than half their population so those people just shit around, even in the big cities, so how the hell could they be trusted to safely operate a nuke?
Fortunately, this will force a rethink of nuclear power plans around the world, though many countries are certain to go ahead with them anyway. Not one single nuke would exist in the world today without government subsidies and exemption from full liability insurance in case of an accident. Not one single bank or investor in the entire world will finance a nuclear power plant without 100% guarantees. They take 6 to 10 years to build and cost a fantasic amount of money and now their power is more expensive than wind power. Still, many countries will continue to build them.
Meanwhile, four different units in the Fukashima complex have experienced serious explosions. The great irony is that the problem stemmed from the breakdown of the conventional pumping systems. The tsunami wiped out the electricity used to operate the pumps as well as the backup diesel generators. Now they are dumping in sea water. These are Hail Mary passes, acts of desperation, last ditch attempts to avoid meltdowns because once the containment vessel is covered in sea water it’s toast as a power facility. Billions of dollars down the drain and the country is experiencing rolling black outs because they now have a shortage of power.
Having four reactors out of control at the same time also seriously complicates matters because it’s hard to work on any one of them with the others so close by spewing their nasty stuff all around you. Moreover, the greatest danger comes not from the reactor cores themselves but the spent fuel rods. They may be spent for the purposes of use in the reactor, but they still contain a lot of radioactivity and generate a lot of heat and require water to be constantly circulating to keep them cool. And further, the spent fuel rods are not enclosed in thick steel containment vessels as the reactor core is and thus in case of overheating will spread their radiation very easily.
There area around those plants will become a permanent exclusion zone. Without protective clothing, nobody will be able to safely go near those plants as far in the future as one can imagine.
There’s been a feeling on the part of climate scientists for several years that global warming could have an impact on earthquake activity. If you remove heavy land ice in places thus lightening up those areas, while adding water to the oceans making them heavier, that may well increase frequency and intensity of quakes. I’m also convinced that withdrawing vast amounts of fossil fuels and water from the earth’s crust has an impact. Finally, the latest natural gas extraction technology – hydraulic fracturing – has shown to be exacerbating earthquake tendencies. The idea is to break up layers of shale to get the gas out. If you take a strong solid shale formation and shatter it into a lot of pieces it has to be destabilizing.
So it can only get worse. The world should prepare, however much it’s possible, for a wave of 100 year, 500 year, 1000 year natural events. And tough luck if you gamble on nuclear power and lose.
