Slightly off topic, has anyone seen it first hand? I was lucky enough a few years back in a UK core pond - I bullied my guide to turn the lights off and it really is quite an eerie site.
not from a reactor (or ex-reactor i.e. a used core)I thought it was an amazing thing to see, very vivid colour.

I've seen it a couple of times - the Imperial research reactor back when it was running and recently at the TRIGA reactor in Mainz. Yes, very eerie!http://www.nytimes.com/2011/04/10/world/asia/10wor...
Interesting insight into working conditions pre and post disaster at the power station. There seems to be a culture of secrecy and cover-up with all the nasty and dangerous jobs going to daily contractors.

This is Japan... is anyone surprised? Interesting insight into working conditions pre and post disaster at the power station. There seems to be a culture of secrecy and cover-up with all the nasty and dangerous jobs going to daily contractors.

Pretty good article - thanks for posting that up!Interesting insight into working conditions pre and post disaster at the power station. There seems to be a culture of secrecy and cover-up with all the nasty and dangerous jobs going to daily contractors.
For all the people who claim there is nothing to worry about (and that goes for the thugs described in the article!) there still seems to be four piles of burning nuclear fuel with enough radioactive ingredients to make Chernobyl look very small, that are too 'hot' for anyone to get near enough to fix.
I maintain my view of criminal negligence, but from the practical point of view it's not that the risks of x Y and Z are small, but that when something does go wrong it gets worse and worse, into a spiral of disaster which has now left a disaster hit country in limbo and many areas simply unable to be searched - let alone cleared and rebuilt.
An iteresting website that shows current readings from a couple of hundred locations. No idea how accurate it is.

Japan to evacuate more towns around crippled nuclear plant:

170 kg per assembly

article said:
Chief Cabinet Secretary Yukio Edano said the municipalities are likely to see long-term radiation levels that exceed international safety standards, and he warned that the month-old crisis at Fukushima Daiichi is not yet over.
"Things are relatively more stable, and things are stabilizing," he said. "However, we need to be ready for the possibility that things may turn for the worse."
And about an hour after he spoke, a fresh earthquake rattled the country, forcing workers to evacuate the plant and knocking out power to the three damaged reactors for about 40 minutes, the plant's owner, the Tokyo Electric Power Company, reported.
I get the impression that all four reactor/pool buildings are still totally out of control, no one has any idea how to fix them and no one can get close enough to assess the damage properly."Things are relatively more stable, and things are stabilizing," he said. "However, we need to be ready for the possibility that things may turn for the worse."

Looks like the Japanese may raise the incident from a level 5 to a level 7. The releases have been of the same order of magnitude as Chernobyl i.e tens of thousands of terabequerels.

Expert reassures me, next fact seems to undermine expert:
"Previously, the damage to reactors at the plant, 137 miles north of Tokyo, has been rated at level 5 on the scale, putting it on a par with the Three Mile Island accident in the United States in 1979. The government elevated the disaster by two notches, a rating that has previously only been applied to the Chernobyl accident in 1986.
The government's decision is based on a preliminary calculation by the Nuclear Safety Commission of Japan that estimated that the plant was venting as much as 10,000 terabecquerels of radioactive iodine-131 into the atmosphere every hour at one point after being damaged by the March 11 earthquake and tsunami.
One terabecquerel is equivalent to 1 trillion becquerels, the agency said, although it now estimates the nuclear plant is releasing less than 1 terabecquerel per hour.
The agency also said radiation beyond the amount considered safe for humans during a full year had been detected up to 37 miles northwest of the plant and 24 miles to the southwest, well beyond the 18-mile exclusion zone the government has imposed around the nuclear plant.
The operator of the Fukushima plant also revealed that it fears the radiation being leaked may surpass the amount that escaped into the atmosphere when the Chernobyl plant exploded in 1986."

From reading the INES site it seems that they still consider each individual event as 5 which is how they've been doing it so far just that now some bright spark has copped that the event should be viewed as one in terms of emmissions and hence the jump to 7 whilst missing 6 on the way.
That must have taken some lateral thinking.
After the event classifications of disasters - really useful tools.

Interesting visit to the exclusion area:
http://rt.com/news/japan-fukushima-zone-radiation/
For some reason the Geiger counters in the car are fixed to the dashboard, so they may be sampling airbourne particles from the vents that the actual levels at the position, but there sounded like a fair amount of activity on there, and some readings are from outside the car.
It's fairly clear to me that the radioactive contamination of the land is pretty serious already, give another couple of months and I dread to think of the exclusion zone size.

The general level for the area is still elevated at 1.94μSv/h.

LLewop would be best placed to determine whether the rate of fall off is significant or not.
The emergency recording equipment still records as under survey for some reason.
http://www.bousai.ne.jp/eng/
So anyones guess what levels they get locally.
Reuters report that remote controlled dozers are removing soil around the grounds of the plant to reduce levels. Don't know what they do with the soil mind.

Can you give us the numbers for 'pretty serious'. Or should we be scared just in case?
Watch the video, listen to the counter, read my post, note my opinion.
You can be scared if you like BTW, I'm not sure why you'd think of being scared though. Are you easily scared? Does talking about something on the other side of the planet usually scare you?
