Sorry, you don't seem to understand the time dosage problem with radiation. In a nutshell, do you think you have the same radiation effects from a single x-ray and you do with an x-ray every day for 2 years?

The numbers you quote are a time dosage - "8217 microsieverts per hour " You then talk about "And I further read that at 250,000 µSv ”Some people feel nausea” and at 1,000,000 µSv there is “Mild to severe nausea”. Makes 8,217 µSv look pretty small to me."

You need to multiply the 8217 /hour X the number of hours of exposure. It takes a day to get to your "mild nausea." About a week to get to severe nausea. Where does the nausea come from? The fast-growing lining of the stomach sloughing.

I've had two parents undergo chemo and I promise you, it is umm, unpleasant. To think of everyone within 17 miles of a Japanese reactor going through that is inhumane but in your blog, you dismiss it.

I am very much with you about learning - but I guess there is a little more to nuclear physics than Wikipedia.

# Lowest clearly carcinogenic level: 100 mSv/year[3]
# Criterion for relocation after Chernobyl disaster: 350 mSv/lifetime
