I’m trying to figure out what microsievert actually is. They show a graph on NRC news, and there’s a live geigercounter in Tokyo right here. Right now, it says: “16,34″. So that’s… 2 point something CT scans? “2.4″ is the yearly amount, apparently.
Reporters from all around the world are fleeing now. They say “the great exodus from Tokyo” has begun. That’s right, when the French run, you better speed it up and run faster.
Edit:
The site also helpfully notes that 100 CPM is about 1 microsievert per hour.
For a bit of context:
As I stated above, one hundred counts per minute in a Geiger counter like this is equivalent to 1 microseivert per hour.
It takes about a full seivert (equal one million microseiverts) to have a risk of death from acute radiation poisoning.
At lower levels of exposure, around 100 milliseiverts, one can suffer some permanent injury (like infertility).
A dose of 1 milliseivert per year is considered a ‘safe’ annual dose of radiation.
So… according to my calculations you would need to stay in Tokyo at radation level say, 16,5 for an entire month to reach over 100 microseiverts. Oh! Milliseiverts… I HATED MATH. Waits! 0.000165 milliseiverts per hour * 24 * 365 = 1,4454 a year. But…. ? The readings in these geigercounters are entirely different… wtf. Look at this one, it says around 30 cpm now, instead of that live video one. That’d be 2.68 a year. Milliseiverts I mean. Anyone that actually CAN count, may correct me here. I’m bettin’ on the graph instead of the video.
Edit #2: Japan reverses the decision, asks EU for help. Dutch have figured out some time ago what they could do for Japan, when the first reactor blew up: “we can builds a dam”. The reporter said it was “not in any way for the near future, but hey”. I thought it was the most hilarious and stupid thing I heard, but then I heard a few days ago a dam had indeed bursted. Not so crazy after all? There’s a team ready with K9′s as far as I hear… though there was talk about them even going.
