Flying in Airplanes Exposes People To More Radiation Than Standing Next To a Nuclear Reactor (businessinsider.com)

Traveling the skies by jet lifts us far from the hustle and bustle of the world below. From a report: But many flyers don't know that soaring miles above Earth also takes us out of a vital protective cocoon -- and a little closer to a place where our cells can be pummeled by radiation from colliding stars, black holes, and more. You can't see these high-energy charged particles, but at any given moment, tens of thousands of them are soaring through space and slamming into Earth's atmosphere from all directions. Also called cosmic rays or cosmic ionizing radiation, the particles are the cores of atoms, such as iron and nickel, moving at nearly light-speed. They can travel for millions of years through space before randomly hitting Earth. These rays don't pose much of a risk to humans on Earth's surface, since the planet's atmosphere and magnetic field shield us from most of the threat.

So, a few things.

One, when you are standing "next to" a nuclear reactor, you still have all of the shielding between you and the reactor. It's not that much radiation.

Two, the article points out how NASA monitors radiation exposure of it's astronauts, but airlines don't do any such thing for flight crews. Again, this is a false comparison. Astronauts pass outside of our atmosphere entirely, while airplanes do nothing of the sort. You may as well complain that they don't provide space suits when you fly on Jet Blue.

Three, they actually do show a little real science...and illustrate that the annual exposure of a full-time flight crew while in the air is about 3 mSv. And they state that 10 days in space gets you 4.3 mSv of exposure. So even by their own numbers, the simple fact is that this isn't a real problem. Effectively, a flight crew gets 4 times the exposure to "cosmic radiation" (as they call it in the article) as a person who is standing on the ground at sea level.

Next up: Businessinsider.com exposes the "massive" amounts of radiation that high-altitude mountain climbers receive. Not only are they really high up (like real astronauts!), they don't even have a plane around them!
