Here is a nice link of live coverage of the event from Japan. They just admitted radiation level at ENTRANCE to the facility is 292 microsiverts per hour, and the fire trucks sprayed water AT the plant for less than 30 minutes. The trucks could not get close enough to get water on the cooling pool and had to be withdrawn due to high radioactivity....

I just asked, because 292 microsieverts an hour is not much at all. You might have your units wrong, you may want to double check.
So it has reduced by an order of magnitude or two? Good.
That means about .3 sievert per hour and I think the annual dose is allowed to be 50 sievert for a nuclear worker. Higher than you would like, sure, time to wet our panties, not yet.
