How much Radiation are we exposed to when flying ??
Curious to know how many micro civets we are expiosed too when flying, if any at all.
The reason I ask is, a part of my job is to fly Live Animals across the world and up until recently they were exempt from X-ray, new legislation coming in says they will have to be x-rayed if they are not from a "known" source (too boring and complicated to explain the "known" part) so I have clients now concerned that their small animals will die in the x-ray machine, they wont thankfully as they recieve a small dose of about 5 micro civets when passing through the x-ray machine. Whilst investigating this I was told by a few people they believed the animals (and the passengers) were exposed to a higher doseage of micro civets when 35000 up in the air for a prolonged amount of time. Any of the boffins on here know the answer ?? |
I am more worried about all that fake tan on the cabin crew.Looks like it could iradiate you at 20 paces!:)

About half a milliseivert per year for a frequent flyer. Normal exposure is 2.5, varying slightly according to where you live.
Edited to say this is well within safe levels for a human, and I'm sure it's OK for animals too. Recent evidence has shown that modest levels of radiation may actually be good for you. |

If you're referring to cosmic radiation then this one of the reasons why flight crews are restricted by Flight Time Limitations but there is so much bull**** surrounding the whole subject that sorting out the wheat from the chaff is difficult.
Suffice to say, that I doubt that the levels of radiation they will experience would be higher to what they will be subjected to in flight. I have forgotten most of the stuff I learnt but try this as a starter for ten... http://www.dft.gov.uk/stellent/group...on_503468.hcsp |

Russia never went there, why? An interview with a Engineer within the Russia space program explained that the reason Russia never went to the moon, is cos they didn't want to kill there Astronauts. He explain that in order to protect the Astronauts from the Suns Radiation, they would have to build the module out of 14" thick lead. Now according to America, they can send several men to the moon and back in a module made of 1mm steel, and none of them have got Cancer, or anything. Let alone died in flight. Ozone layers that protects us from the Suns radiation? Why are we bothered? according to America, all we have to do is build out houses out of 1mm steel sheeting or sit in our cars, and everything Will be hunky Dorry :freak3: |

Thankyou :) |

Thankyou :) Solar flares were the concern, not background radiation. |

Solar flares were the concern, not background radiation. To get to the moon you have to leave the ozone layer. that's when you need 14" thick lead protection. |
If the space station was in the ozone layer (or below) wouldn't it heat up with friction as it's going umpteen thousand of miles an hour ??

You don't need 14" of lead to stop most forms of radiation - their windwos are enough to stop alpha radiation for example. The biggest risk they faced was the radiation from a large solar flare... and they lucked out!

I did a bit of a google and the only thing I can find is a CT site on the lunar landings and that claims 4 feet of lead was required. But they don't give any references or workings, it's just wild unsubstantiated claims. |

As we know America never lies for it's own gain, does it. Solar flares, as both Top Banana and I have said were the main risk. Radiation is present in "belts" - its not everywhere in deep space in equal measure. Solar flares emit huge bursts of radiation, and yes, you would need substantial shielding (or the earths magnetic field which deflects the radiation away) to avoid being heavily contaminated. IIRC (not having googled) its the Van Allen belts (?) which were a further risk to the apollo missions. The ozone layer absorbs UV radiation. You don't need 14 inches of lead to do that. Now, having googled, the bloke after whom the belts of radiation are named is quoted as saying "The recent Fox TV show, which I saw, is an ingenious and entertaining assemblage of nonsense. The claim that radiation exposure during the Apollo missions would have been fatal to the astronauts is only one example of such nonsense." -- Dr. James Van Allen So, in summary, you are talking ****e ;) |
I managed 38 years worth of that kind of radiation. Don't know whether it was the cause of my recent operation though. More like red meat and pesticide use I reckon.

Some truth in it........... one person on here is almost certainly senile, and he flew for over 30 years...... <uncle albert type> "during the war................ :sleep: " .......... ;)
