A friend in Tokyo reports radiation 5X over background this morning.

This morning, a friend in Tokyo reported to me that he went for a walk in the rain. When he came back, he checked his feet and clothing with a geiger counter and came up with a reading five times over normal background radiation -- enough to register significantly on his meter.

The wind in northern Japan has been blowing south the last day or so and is expected to continue blowing South for the next couple of days until the rain storm moves through.

1. I don't know enough about this subject to have a solid opinion -

in this case, I'm wondering if 5 X next to nothing is still next to nothing, or something to worry about. OTOH, I recall reading that determining the "acceptable" dose of radiation had far more to do with the cost of reducing radiation exposure below a certain point than the harm of exposure above that point.

2. As doses go, it's nothing. But...

It does mean that radiation is being released from Fukushima north of Tokyo, in significant amounts if it can be detected easily as far south as Tokyo.

Also, when the puddles dry, the radiation will be more concentrated in dust that can be inhaled. Then it could be a real danger.

I'm hoping to get a reading from one of the dried puddles in a couple of days. I'll post an update then.

3. Rain may have put iodine in Tokyo water
