RADS ON A PLANE--NEW RESULTS:
NASA has released o new report on radiation absorbed by crew and pax in various areas and altitudes. They have a weekly newsletter Spaceweather.com that covers these and other topics. There is no practical way to prevent space radiation from entering the cabin - They are unlikely to start skinning airliners with a thick tungsten skin or use lead wool insulation
Definitely worth reading and wondering what a lifetime of flying, particularly in the Artic will bring. And its from a reliable source.
A quote:
Here is what we have learned so far:
Radiation always increases with altitude, with dose rates doubling every 5000 to 6000 feet. This make sense: The closer you get to space, the more cosmic rays you absorb.
At typical cruising altitudes, cosmic radiation is 40 to 60 times greater than natural sources at sea level.
Passengers on cross-country flights across the USA typically absorb a whole body dose equal to 1 or 2 dental X-rays.
On international flights, the total dose can increase ~five-fold with passengers racking up 5 to 6 dental X-rays.
