Radiation Not As Hazardous As Once Believed 570
HeavensBlade23 sends in an article from the German site Spiegel Online about mounting evidence that nuclear radiation may not be as deadly as has been widely believed. The article cites studies by German, US, and Japanese researchers concluding, for example, that fewer than 800 deaths are attributable to the after-effects of radiation in over 86,500 survivors of the Hiroshima bombing. Other surprisingly low death rates are reported in studies of Chernobyl and of a secret Siberian town called Mayak, devoted to producing plutonium, that was abandoned after a nuclear accident in 1957.

A very important point to note is that the determination that no level of radioactive exposure is safe does not mean the same thing as low levels of radiation are extremely dangerous (which many might believe). What the doctors are literally saying is that they don't consider a 10^-20 or even a 10^-40 Curie source to be perfectly safe. One errant gamma ray from the decay of some radioactive substance might be enough to cause a fatal cancer. As there is no safe level of exposure to asbestos, PCBs, or arsenic, reasonable limits are proposed where very few people are injured by these substances. The same applies to radiation levels. If the danger due to low level radioactivity is determined to be a thousand times less dangerous than we thought it was then the exposure limits might be raised if convenient, but radioactive material will still not be considered safe, even in the smallest amounts.

Spent fuel is stored encased in glass and concrete. The risk of leaks is very small, and because the low volumes of waste can be concentrated in a few locations, only small areas would be contaminated even if there was a leak.
The Chernobyl plant was a very poor design and nobody is pursuing similar designs any more. The RBMK design encased the fuel in flammable graphite as moderator. When the reactor overheated and the hot graphite was exposed to the air a raging fire immediatly began, tearing the reactor core apart and sending particles of spent fuel into the air in great clouds of smoke. Water moderated designs obviously don't have this problem. (The experimental pebble-bed reactors are graphite moderated, but they are much less likely to overheat.)
The bombs used in Japan were also very dirty. Modern designs consume a much larger part of their fuel. The chief danger is that setting off a nuke on the ground will mix the nuclear material with dirt, causing concentrated fallout within a few miles of ground zero, instead of dispersing it relatively harmlessly in the atmosphere like an explosion in mid-air.

1) You are absolutely right about bad figures. On average, coal-fired plants produce much more exposure to radiation than nuclear plants and this is generally ignored by the anti-nuclear folks (of which I still count myself one). However, I will say that if it were a choice between coal (lots of green house gases, radioactive pollution, etc) vs nuclear (waste disposal issues, etc) I would choose the latter. In short, nuclear may be bad, but coal is definitely worse.
2) We need to understand that energy use has environmental cost. Simply throwing more power generators at a problem doesn't fix it. We need to do what we can to minimize that cost and this means a multi-level strategy. There is no magic bullet. A few nuclear power plants may be necessary but if we are smart we will pursue a number of other means first.
3) Cost per kWhr is not the only measure of energy's real cost. I think one must factor in the total environmental cost as well. This includes carbon consumption, hazardous waste disposal, environmental cost of production and disposal of generating equipment etc. We need to start at the bottom and work our way up. This means:
a) Conservation-oriented policies. Let us help try to get people to push for more energy efficiency in general so we don't need as many generators as we might otherwise.
b) methane from manure composting from dairy farms which may have close to a net zero cost. (On one hand capturing/burning the methane is *good* for the environment. On the other, the equipment still has to be manufactured and disposed of.)
c) Encouraging thermal solar energy use from areas where one would normally waste the energy is another proven area where we could come out ahead in terms of general conservation.
d) Wind power, properly done, is something I would call low-cost.
e) Any other ideas on agricultural waste, esp. the stuff that normally just gets burned?
f) fish-friendly hydroelectric dams
g) Current generation of nuclear reactors should replace coal generators.
h) More research needs to be done on renewable energy sources, and on storage and transmission systems (I think that ultracapacitors should also be seen as a green alternative to batteries in wind generators, for example).
h) More research needs to be done on fuel cycle issues and how to effectively eliminate waste (for example, by using the waste as fuel in other nuclear reactors)
I don't think it is an either/or question. I am not convinced that it is practical to use renewable energy at the current generation for current or future electrical needs, but I would think that everyone should be in favor of minimizing the role of non-renewable energy (in general) and the environmental cost of energy as a whole. Nuclear almost certainly has a part to play, but let's not make it any larger a part than it needs to be.

With no room for giant car lots and showrooms, the routine method is for a sales team to come to your home or office, where they painstakingly go over every option. Once you've made your choices, and honko'd all the e-forms, the wait begins. You wait while your car is built. And before you can have your purchase approved, you must show proof of having obtained an appropriate parking space. Many times, new car owners have to wait for a parking slot to become available long before they can even think about what color interior would go best with the wife's wardrobe.
Once you have the parking spot and car buying process behind you, a new list of routine obligations must be met. Like full car inspections at intervals designated by the manufacturer and (ahem) backed by the govt. You don't take the car in and ask for this or that to be looked at or fixed...nooo. They come and get the car, and then contact you with the list of things that must be done, along with how much it will all cost. No choice - pay up. Think of the whales. At one time, there was an anti-pollution law that said a new engine had to be installed every two years. Ever wonder why all those low mileage Toyota truck engines are for sale here in North America? Ever wonder how so many foreigners found it easy to get a car in Japan? Maintenance costs can be so high, some owners simply give the car away and go out and buy a new one.

Basically everyone pays a couple thousand bucks to a driving school to take courses for several months, after which you have as many chances to take the "test" at the driving school as you want, several times per day, and any day you want. Of course, the real test held at the government license center is harder, held only on weekday mornings if you're lucky, and the "rules" of the test bear no relation to actual driving. Don't get me started on the oogata bike test. That thing is even more of a swindle.
You are correct that the roads are not safer. In fact, almost none of the roads have reflective markers for rainy conditions. No "cat's eyes", no Botts' dots [wikipedia.org]. Drivers do not switch their headlights on in fog or rain or snow; I had three or four drivers actually flash their brights at me on Sado island for driving in a rainstorm with my headlights on last weekend! People here often stop in the middle of the road to answer a phone call, often on a blind curve. Ah, but at least they're not driving while talking on a phone... I guess their abysmally low speed limits are an attempt to make up for these deficiencies.
The road system is set up to be a big cash cow for the government. You are correct in that aspect.
The wrong:
The shaken inspections aren't mandated by the manufacturers, they're mandated by the government: after 3 years for a new car and every 2 years after that. Unlike US car inspections, they check more than just emissions: brakes, suspension, tires, transmission, all the lights, seat belts, and steering are among the things tested. The inspection itself winds up costing about 10000 yen plus any repairs, but you also pay taxes for two years at the same time, which is why it's so expensive. If you know a reputable repairman, the repairs will not cost that much. My guy gives me a loaner car while he's working on mine, no charge. Alternatively, you can do the fixes yourself and take the car in for inspection on your own time if you can get the time off work, which saves a bit of cash if you're handy. I do think this helps keep unroadworthy cars off the streets, and in that way helps safety... but it does cost an arm and a leg. You do have a choice: if it's too expensive to fix the car up to snuff, you scrap it. Part of owning a car means making sure it's not an accident waiting to happen.
Proof of parking space is only required in big cities: Tokyo, Osaka, Nagoya, basically any metro area. If you live outside those areas you don't need proof of parking. And there are plenty of car dealerships outside Tokyo where you can walk in, pick out and buy a car from the lot, and have it delivered to you or pick it up within a few days (after they fabricate the plates, no temporary tags here). If you haven't seen them, it's because you haven't been outside big cities.
Maximum expressway speed is 100kph outside cities on multiple lane highways. Where I live, congestion is rare because the expressways are only used for long trips. In clear dry weather most vehicles cruise between 100 and 120. If you live in Tokyo, don't get a car to drive to work every day, because you're right, the highways can't support that many people. But the only speed enforcement is fixed cameras and the rare patrol car (and there are unmarked cars as well, so be careful). Thankfully, almost everyone is courteous enough to pull over when they're not passing. I've seen a couple folks taking stretches in excess of 150kph on twisty road, and the rest of traffic just moves over to let them go. Assuming they have the space. But unfortunately the roads are not banked for the speeds their surfaces and widths support. And they are extremely overpriced.

I don't know if I would trust the state of NJ more than I would trust the Soviet government that was present in 1986. To be honest with you, may be in 50 years we will know 1% of the true effects. Remember how cocaine was legal in the United States?
One of my most exciting moments of my childhood was the rain of April 26th, 1986. I was walking from the hospital when it started raining and I got soaked by the time I got home. Several days later we were told to throw away the clothing used on that day and take a long shower because a chemical plant not so far away had a problem. Cool huh? As somebody who was under 10, it was "it!" I was a part of something that the government asked me to do. It felt great until my mom got a call from my grandmother: My uncle was traveling to Belaja Tserokv' (White Church) with a his chem-bat (chemical forces battalion). My grandma was a nurse and she suspected that something was going on since they tons of firefighters were shipped to the area. It was highly unusual to send that many people for a small chemical spill at a nuclear plant. I will skip you the stories about carefully re-adjusted radiation meters given to the soldiers and other tricks that were used to keep public away from the information about the real aspects of the accident. Everything was "peaches and cream" according to the top brass. My uncle delivered cement to the reactor thinking that they were putting down some important fire. Only later we were told about the nuclear disaster and its impact. During the times of Perestroika this became more public and we finally realized what has hit, but it was too freaking late.
I would like to come back and visit the ghost areas. Many areas of Belarus and the Ukraine (Belarus was hit the hardest due to the North-Western winds) became ghost towns. It is a lot like what you can find in the prominent historic parks of the U.S.: Whole towns are there, but no people want to live there for the exception of an occasional squatter. You may see a Western tourist here and there and that is about it. Whoever thinks that radiation is not damaging needs to get their head examined. Yes, a direct death from the exposure may be unlikely, but I'd rather not wait for the long term effects. Honestly, I have seen that stuff and it is not pretty. I'd take a bullet over slow death any time.

The article was refreshingly in-depth and it covered both sides of the issue - surprising, considering most ./ articles are not much more than short blog rants. I do wish it had pointed readers to an online location of the studies cited, but the reports are verifiable. I was aware of cooperative studies done after WWII by the US and Japan, among others.
My gut reaction is to accept the information presented as reliably true. I have two reasons for this. First, this was published to a German site. I trust a German site slightly more than your average dot-com because of the competing forces at play in the current US 9/11 mindset. The Bush "gubmint" wants you to cower in terror every damn day fearing random acts of violence by brown people (Appropriate thanks to George Carlin). The more peaceful side of the US continues to try to reassure the public that much of the terror threat is FUD (which it is - seriously, we've been at the Orange terror level for months, meaning "High Risk of Attack". No attacks, no highly publicized failed plots to garner support for the omnipresent Orange. I doubt the FBI/CIA/DHS is doing THAT well). I admit the US has its enemies, and that fact should not be discounted. It's true that someone may someday use a nuke (or more likely a dirty bomb) in an American metropolis. But if this was posted to an American website, I would have a harder time accepting it at face-value, rather than subtle "fear not" messages by pro-nuclear lobbyists. That said, as an American citizen in a metro area, I'm happy to see that moderate radiation may be tolerated by the body better than expected, and i am also in support of more nuclear power plants in the US. Nuclear power done right releases less radioactivity into the air per year than a coal plant...and probably less than the pack of cigarettes I'll finish tonight.
Second, the effects of short-term radiation exposure are typically exaggerated, in my non-professional opinion. A chest X-ray for example, is roughly equal to 10 days' worth of background radiation dosage; fewer if you live 5000 feet or more above sea level. Not bad considering your heart and lungs are the target of a quick 120,000 electron-volt blast (Linkage) [netdoctor.co.uk]. Cancer treatments can exceed 10 MeV. Granted, I'm talking about reasonable short-term exposure, something less than 3 or 4 Greys for a one-time worst-case scenario. I'm not going to argue that pulling a Spock and walking into a reactor for a while will leave you anywhere near healthy.
I think long-term radiation exposure is where we need to concern ourselves. For example, Marie Curie handled radioactive material with little to no protection for nearly 40 years, before dying of anemia in 1934. This can be partly attributed to the fact that much of the radiation she was exposed to was alpha radiation. However, long-term exposure to radium (which is over a million times more radioactive than uranium) and its byproducts, including radon gas and ionizing beta particles most likely led to her death. Gamma radiation is much more harmful, with the ability to knock base pairs out of DNA. Even the most loved radiation of all, UV, that elixir of youthful bronzed skin, has been shown to cause harm. But no one gets carcinoma from a single sunburn, or a single tan. The most deleterious effects add up over time, but are not caused by forgetting to slide the lead suit over the family jewels during an X-ray at the dentist.
Saying that only 800 or so out of 86,000 survivors died of radiation-related illness is not enough for me. How many showed non-fatal illness extending beyond 1 year of exposure to the bomb? What was the change in infant and child mortality 5/10/20 years after? How did the population histogram change over time - were elderly affected more than children or vice versa? How much radiation WAS deposited to the environment after the detonation of Fat Man/Little Boy -- accident at Chernobyl -- accident at Three

Low Dose effects of radiation (Score:3, Insightful)
But there's extensive research [magma.ca] being done today [marie-curie-prize.org] which seems to be indicating that low-dosage radiation is not only non-lethal but can actually be beneficial [lbl.gov].
I saw recently a (BBC?) documentary about ongoing research into the effects of radiation exposure. Basically we have *more than enough* evidence of the effects of short-term high-dosage (the upper/right side of the curve) but damn close to zero data regarding the lower/left side of the curve.
The does seem to be evidence that in some cases ongoing exposure to (relatively) low-level radiation (but still higher than "generally accepted" levels/"normal background" levels) is actually beneficial.
There was some village (Israel/Palestine/Middle-East 'ish') where the natural background radiation was something like two-hundred (200) times "normal" levels. The people there were perfectly normal, fine and healthy. In fact, researchers found the villagers were more healthy than normal/average for some diseases/conditions.
From Memory: I think the science is currently leaning towards the theory that even with radiation (which previously we thought that *any* was bad), "a little" can be good because it basically prompts the bodies natural response to damage/injury (eg in the same conceptual way that an innoculation helps prevent disease) .
Not that I'm pushing "radiation is good", but there's more than enough evidence to show that we clearly do not fully understand all the implications of exposure to radiation, especially when it comes to ongoing low dosage exposure over long time periods.

That's right. For example, from the ionizing radiation article on wikipedia [wikipedia.org] (units in mSv -- 1 mrem = 0.01 mSv):
260 Ramsar, Iran, annual natural background peak dose
175 Guarapari, Brazil annual natural radiation sources
50 USA NRC annual occupational limit
3 USA average dose (per year) from all natural sources
I don't want to sound like a troll, but radiation safety in the US is almost certainly far too conservative to the point that it has made the public (including many slashdotters, apparently) su
Radiation hormesis (Score:4, Informative)
We have more or less only one good epidemiological set of data for various-dose radiation--atomic bomb survivors. Those data are extrapolated to low doses, and that's a large part of the data set from which the current "radiation damage" model (the LNT or "linear-no-threshold" model) is derived (actual survival of cells is predicted by a different model--the LNT model is for radiation effects on a person). Since the LNT model is the most widely-accepted standard in the field as far as I've seen (medical physics student), the hormesis promoters have the burden of proving the protective effect.
The parent is right in that we don't have a good understanding of what goes on at low doses of radiation, and we don't have a model backed by strong empirical observation either. Radiation protection, however, is founded on the principle of keeping doses as small as is reasonably possible, and it's irresponsible to try to wave around that small doses MIGHT not be as harmful as people currently think. I would say that radiation science still basically wants to say that there is no lower threshold for radiation damage, and thus that there is probably not a hormesic (hormestic? I don't know the adjectival form of hormesis) effect. It doesn't really need to be stated that we don't know a lot about low-dose radiation--you start from the assumption that you don't know a lot about it until you can prove that you do. Right now, all we can prove is that it's pretty likely that if damage is linear, then low-doses are bad too.

This article is from a German magazine, and the research was done by the GSF under the Helmholtz-Gemeinschaft foundation, Germany's version of the NSF. Are you referring to Germany as "the country?"
The article ends with "Still, there is no doubt that radiation poisoning remains ominous and highly dangerous."
Wow, that's some powerful FUD being thrown around right there. (Ominous is an odd translation of a German word, which means something close to ominous/foreboding/nasty/etc...)

I am aware that Browns Ferry had a fire in the 1970's, but you've made me think of an interesting point. The water used in a reactor's triple cooling loop *should* remain separated twice over from the working fluid of the core. Heat is exchanged from the liquid sodium in the reactor, creating steam to drive the turbines. The steam is cooled in the evaporating towers, aided by a separate water supply which is often circulated into a lagoon/lake. The water temperature leaving the cooling towers is around 30C
