U.S. EPA RadNet
The Likely Radiation Distribution in Japan (March 19)
Added 3/22:
Iodine from plant detected in Tokyo: .046 µSv/hr. (438 µSv per year — about 4 chest x-rays); Fukushima Pref.: 21.9 µSv/hr. (191,844 µSv per year or 1918 chest x-rays).
Dealing with radiation fears, potassium iodide requests: side effects include nausea, diarrhea, allergy, interference with the body’s normal production of thyroid hormone.
Iodine facts (American Thyroid Association)

Concentrated sources of Iodine include kelp (best), yogurt, cow’s milk, eggs, strawberries, mozzarella cheese, fish, and shellfish.
Added 3/22:
U.S. Nuclear Regulatory Commission: “Doses in Our Daily Lives”: medical procedures, food, Personal Annual Daily Dose Calculator. On average, Americans receive a radiation dose of about 0.62 rem (6200 µSv) each year (100 rem = 1 Sv = 1000 mSv = 1,000,000 µSv).

This is a bit disingenuous. Take the time to look at the actual link:

Note that the above truncated chart leaves out the interesting item that a flight from NY to LA is roughly equivalent to 2 chest x-rays, or that a chest CT scan is 6 times the external dose from Three Mile Island.

Yeah, I’m a bit surprised that you’ve only included this tiny bit of the whole chart. Why this bit, anyway? It’s the chart taken as a WHOLE that makes its point and provides context.
