Thread is about the various issues surrounding Japan in the aftermath of the recent earthquake. Don't bring the shit side of the internet to the thread, and post with the realization that this thread is very important, and very real, to your fellow members. Do not post speculative and unconfirmed news you saw on TV or anywhere else. Generally the more dramatic it sounds the less likely it's true. | ||

It wouldn't be cancer. And that's insane, they're going to evacuate more than 20km. | ||

There will be no explosion but if a meltdown occurs then you have nothing between the radioactive fuel and the outside environment, as well as liquid metal melting down through the layers of the structure. If this material reaches groundwater, it can spread uncontrolled and that can very be bad. There will be an airborne release as well, this can also be very bad and render the area surrounding the plan uninhabitable for many years. But there is no risk of an explosion. Please don't speculate, this is no place for fear mongering. fuck that had me worried, but still man, i hope one day we can find a better way to produce energy, im sure even without meltdowns nuclear power is still damaging in some long term way. but no time for thread derails! plant tech's are indeed HERO's~! | ||

We expect most of the workers will have a moderate dose over a couple weeks. "Doomed" as in they're going to die this month? Of course not. "Doomed" as in they've dramatically shortened their lifespan by decades? Certainly. Boblion is on the same page as me on this. | ||

It is pretty much unknown what the effects of longterm exposure is but it is 100% certain that you can't extrapolate the data like a lot in this thread tries to do. There are actually studies that shows that a small dose of daily radiation might actually be protective against cancers due to increased activation of the DNA-repair mechanisms. | ||

What could be the cause of that increase ? Is the containment chamber breached as some people say ? What are the realistic options ? | ||

387.3 uSv / hr was the final measurement I believe. | ||

The only experience humanity has with exposure to these levels of radiation are Hiroshima/Nagasaki and Chernobyl - in all 3 cases the people were exposed to a lot higher doses AND much shorter amount of time.

There are actually studies that shows that a small dose of daily radiation might actually be protective against cancers due to increased activation of the DNA-repair mechanisms. Mmm Chernobyl was like 2000-5000 Sv/h next to the reactor which yeah is quite a bit higher than this, but this still is such a high amount that it wouldn't be safe for extended periods of time. Of course just 1 hour in it might not be a problem but imagine if it stays similiarly for a year... that's going to have an effect. | ||

That makes sense. There would be an acute spike in the measurements after the explosion (at least if it was hydrogen induced like the previous ones) because the vented radioactive steam would disperse. But this is starting to surpass TMI. Not necessarily in impact but in the amount of connected incidents. I wouldn't be surprised if it gets upgraded to a 5 pretty soon, especially with the amount of damage to the cores that is suspected. Still, unless we get more and reliable confirmation about the containment integrity of #2 this is all just speculation. | ||

They're doing a job that, in a free, democratic, society, they don't actually have to do - they could run for it, they could do their best to save themselves - but they're not. They're rolling the dice with their lives to protect the lives of others, so show them a bit more respect. I was under the impression that taking interest in their fates is showing them respect. Don't start arguments over absolutely nothing. | ||
