I don't have time/energy right now, but I am planning to calculate in the near future how much extra radiation I am taking in just due to flying;
I am quite sure the resulting amount will still be negligible; but I am still curious...
I found some info at:
What do you guys and gals think?
|Terrestrial + house: radon||200||200-100,000|
|Terrestrial + house: gamma||600||100-1000|
|Cosmic (at sea level)||300|
+20 for every 100m elevation
|Food, drink & body tissue||400||100-1000|
|1500 (plus altitude adjustment)|
|From nuclear weapons tests||3|
|Medical (X-ray, CT etc. average)||370||up to 75,000|
|From nuclear energy||0.3|
|From coal burning||0.1|
|From household appliances||0.4|
|Skiing holiday||8 per week|
|Air travel in jet airliner||1.5-5 per hour||up to 5000/yr|
The International Commission for Radiological Protection recommends, in addition to background, the following exposure limits:
for general public, 1,000 (i.e. 1 mSv/yr)
for nuclear worker 20,000 (i.e. 20 mSv/yr) averaged over 5 consecutive years
Air travel in jet airliner1.5-5 per hour
20 intercontinental, average 11 hours: 11 * 20 * 4 = 220 * 4 = 880 (estimated at 4; relatively high and long)
40 inland in china; average 3 hours: 3 * 40 * 3 = 360 (est. value to be 3; lower; relative more take off and land)
total 1240 mS
ramoneur, Check your math, I always used REM and never figured out the metric. but if you are saying you absorb 1230mS per year and have been doing this for a few years I think you would be turning pink.
Here is a good reference, it tops out at 1000ms which is when the victim starts to get sick.
"The corresponding annual effective dose, based on 700 hours of flight for subsonic aircraft and 300 hours for the Concorde, can be estimated at between 2 mSv for the least exposed routes and 5 mSv for the more exposed routes."
I have read about radiation exposure from flying, and without verifying your data sources or analyzing the numbers, I choose to simply not worry about it. Flying on average about 55,000 miles/year, I am nothing like a true frequent flyer. The way I look at it is, if long haul flight crews aren't dying from it (prolonged exposure to cosmic radiation), then it's likely that I have nothing little to worry about.

I am still young enough to be rugged and strong
(yes I know the results will check in about 10 years later)
...but I had days in Beijing where even I had breathing problem
if you have the chance, yes, avoid
the mountain-surrounded capital of Beijing makes the local coal mining and burning problem awful
and I am not even mentioning the terrible traffic problem
I once asked a taxi-driver when there was no traffic jam in Beijing
he turned out to have my sense of humor when he replied:
"on days where the moon is in the first quarter, on Sundays, between 02:00h and 03:15h"
