> an excuse to paint nuclear power as completely unsafe and dangerous 50 people sacrificing their lives so that anything even shittier would not happen "is safe and not dangerous"? I fail to imagine what you really find "unsafe and dangerous".

What people are you talking about?

At Chernobyl, this actually happened inside the containment vessel and the resulting explosion ruptured the vessel, leading to a serious release of core radioactives – though this has had basically zero effect on the world in general nor even much impact on the area around Chernobyl. Even just as a matter of rhetoric and persuasion, I think trying to argue that Chernobyl wasn't all that bad isn't the route you want t…

The National Geographic article, the author links to, states that

  The effects of the Chernobyl catastrophe are still being felt today—whole towns
  lie abandoned, and cancer rates in people living close to the affected areas
  are abnormally high
  
then goes on to say that

  But it turns out that the radioactive cloud may have a silver lining. Recent
  studies suggest that the 19-mile (30-kilometer) "exclusion zone" set up around
  the reactor has turned into a wildlife haven.
  
So basically, the accident at Chernobyl turned the area into a wildlife haven, because it was left to wild animals. If this were to mean that Chernobyl had a net positive effect, it would still contradict the author’s claim that there hasn’t been “much impact on the area around Chernobyl”.

I think it might be time for those who don't have a clue to stop talking about this. People are and will be diing because of what is happening now. Calling this "ok" and "safe" is borderline obscene.

Plus, as told in other comments, this article dates back to yesterday and recent news are less and less reassuring (e.g. the containment vessel is now broken in one reactor).

Thank you.

... I'm not one of the "OMFG LOOK AT THE NUCLEAR ANGEL OF DEATH" people, but can we wait for this crisis to reach some resolution before we make loud proclamations either way? The main information that concerns me right now is that there appears to be a consistent radiation leak of 400 mSv/h at the plant. While not Chernobyl by any measure, this is quite a bit of radiation, considering one's yearly dose limit is 1 mS…

"considering one's yearly dose limit is 1 mSv total." In Ramsar, Iran the background radition is around 200 mSv/Y (compared to a worldwide average of 2.4 mSv/Y) and _according to wikipedia_ this "high level of radiation does not seem to have caused ill effects on the residents of the area". Call me confused. Is the 1 mSv/Y total one of those made-up safety guidelines?

Well, it's prudent to low-ball the dosages in safety guidelines.

Regardless of whether or not the situation is under control, I think the triumph is more for the Japanese. I'm sure that if the plant were in Greece the fallout would have been much greater because everyone would have cut corners and not followed the safety procedures.

Agreed. It is nice, however, to read coverage of the event that's devoid of sensationalism.

When an editorial is so desperate to take a contrarian view to what everyone else is saying it starts claiming Chernobyl didn't affect the area much (linking as supposed evidence to an article whose second page is entirely devoted to observed negative effects of the radiation on the wild animal population two decades later...) it's ill-researched sensationalism itself. I realise The Register may have published the st…

It is a curious social phenomena that people often want to believe the best possible interpretation even when the evidence shows that things are not going well at all. In this case denialism is probably a strategy to avoid panic, which could have even greater negative consequences.

1 mSv is estimated to increase your odds of serious medical complications by 1/1,000,000. Not a significant amount, but one's regularly allowable dose should not be expected to cause health problems in the first place. Also, these limits are very conservatively set for various reasons - most of which I agree with (used to work in a nuclear facility).

So no, if you got blasted with 10 mSv all at once you shouldn't expect to vomit blood or fall over dead, but it's still a sizable amount of radiation.

Also, 400 mSv/h is 3,504,000 mSv/Y (aka 3504 Sv/Y, aka 17,000 times the radiation output in Ramsar, Iran). Of course, one doesn't expect this radiation leak to last for a whole year, but the dose rate does matter. Sucking in 400 mSv over an hour is many, many times worse than getting it over a matter of years or decades.

The physics and physiology of radiation exposure seem to be quite complicated. I can't really answer your question, I'm very far from qualified to do so, but again _according to Wikipedia_ the short term effect of 0.2 Sv per day, let alone a year, seems to fall into the "no effect" category[1]. And according to this[2] post on Boingboing, the long term effect may not be as bad as one might think either.

Enough articles "everything is fine" for my tastes circulating onto Hacker News, while instead the facts created more and more concerns. I think it's better to just wait, and hope, instead of blabling about things that even the top experts of the world are having an hard time to figure. There will be a time, in a few weeks, and hopefully after a disaster was avoided, to speculate about the real security of nuke power…

Sadly within a few weeks, armies of anti-nuclear campainers, writers, and politicians will have jumped on this and pumped it so through the roof that, even if everything in this article is correct most people won't listen. Look at Chernobyl or Three Mile Island (study after study found no major exposure by anyone).

The hysteria over this is caused by the anti-nuclear people and groups trying to use this as a case against nuclear power, blowing everything out of proportion before any facts are known.

I think a few articles calling for calm balances the shrieking cries of "meltdown imminent".

It wasn't that bad at all. In every discussion about Charnobyl I link this (translation from Polish) http://goo.gl/Djbag

> So what Chernobyl has taught us?

> That nuclear energy is the safest source of energy currently available. The Chernobyl disaster was the worst we can imagine a nuclear power plant. In addition, Chernobyl defied every rule of safety. This property was one big scandal. But that's not all. Following the outbreak of the reactor were released into the atmosphere huge amounts of radioactive substances, which reached even to Antarctica. And what? And nothing. Killed 31 people - less cluttered than in January hall in Chorzow. Dangerously contaminated was less than a square kilometer of land.That's it!
