flying and an increased dose of (cosmic) radiation

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:

http://www.world-nuclear.org/information-library/safety-and-security/radiation-and-health/radiation-and-life.aspx

 

What do you guys and gals think?

 

 

 

Typical µSv/yr 

Range 
Natural: 
Terrestrial + house: radon200200-100,000
Terrestrial + house: gamma600100-1000
Cosmic (at sea level)300

+20 for every 100m elevation

0-500
Food, drink & body tissue400100-1000

Total

1500 (plus altitude adjustment)
Artificial: 
From nuclear weapons tests3
Medical (X-ray, CT etc. average)370up to 75,000
From nuclear energy0.3
From coal burning0.1
From household appliances0.4

Total

375
Behavioural: 
Skiing holiday8 per week
Air travel in jet airliner1.5-5 per hourup 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

    quick calculation:

     

    Air travel in jet airliner1.5-5 per hour

    http://www.world-nuclear.org/information-library/safety-and-security/radiation-and-health/radiation-and-life.aspx

     

    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)

    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 agree

      a few days breathing Beijing's air is far worse

      (coals burning also generates radiation ;-))

       

      ...still I want to know;

      and I will find out

        Beijing air quality is enough to keep me away from there.  Won't be visiting New Dehli any time soon either.

          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"

      Good point about the flight attendants, Pluto. If they remain healthy we should be ok!
