this thread DUmmie flamindem posts a link to a nice graphic illustrating relative exposure levels for different activities.
The chart shows the average annual exposure and one airline trip from NY to Tokyo.
Of course DUmmie nadin knows nucleer and she must make some comment on all posts associated with the nukes in Japan.
First she needs to show what she leanrt from Wikipedia.

3. How many milliSieverts in a Roentgen or in a millicoulomb/kilogram?
Maybe I'm old fashioned, but I still think in Roentgens.

6. and I think in rads Updated at 10:25 PM
SI multiples and conversions
Frequently used SI multiples are the millisievert (1 mSv = 10−3 Sv) and microsievert (1 μSv = 10−6 Sv) or (1 mSv = 0.001 Sv) and (1 μSv = 0.000001 Sv).
An older unit of the equivalent dose is the rem (Röntgen equivalent man). In some fields and countries, the rem and millirem (abbreviated mrem) continue to be used along with Sv and mSv, causing confusion. Here are the conversion equivalences:
1 Sv = 100 rem
1 mSv = 100 mrem = 0.1 rem
1 μSv = 0.1 mrem
1 rem = 0.01 Sv = 10 mSv
1 mrem = 0.00001 Sv = 0.01 mSv = 10 μSv
Then the smack down showing she doesn't have a clue.

2. But but I have been told that flying exposes me to more Updated at 10:25 PM

Are you comparing the 0.2 number, described as a plane trip from Tokyo to New York, with the 2.4 number which is the ANNUAL amount of natural radiation (world average)?
Because it seems from these numbers that flying does expose you to much more than a day in the sun.
2.4/365.25 = 0.006570
So in one day of natural exposure to radiation you would receive (on average) about 0.0065 mSv while on that one plane trip you would receive 0.2 mSv.
