Massive Earthquake In Japan Triggers Tsunamis

[Haggis@wk]

Radiation levels in Japan vs. radiation levels in-flight.

yeah...except a flight only lasts for a few hours

I don't know enough to interpret the chart so I had to dig around. The peak of over 3 uSv equates to 30 mSv, and the radiology link says that's a moderate exposure, adding slightly to our risk of dying from cancer. But it's 100 times what the rad. link says we're exposed to on a coast to coast flight.

and...I wonder if any of those in-flight spikes were due to airborne radiation from the plant as opposed to "background" radiation.

I wonder if any of those in-flight spikes were due to airborne radiation from the plant as opposed to "background" radiation.

Certainly they were. The radiology link gives a figure of 1% of those readings for a trans-con flight. No isotopes were id'ed, but where else would such a quantity come from?

[jamiebk]

I'd be more concerned with breathing that particulate

Something to pay attention to, but not necessarily alarming.

Another big earthquake, although I think it's considered an aftershock. Time for everyone to leave Japan.

With shifting, sinking, and shaking, seems Japan is trying to leave everybody.
