Flying in Airplanes Exposes People To More Radiation Than Standing Next To a Nuclear Reactor (businessinsider.com) 275

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.

      Spot on!

      Reading the line "tens of thousands of them are soaring through space and slamming into Earth's atmosphere from all directions" my first reaction was:

      Divide "tens of thousands" by the surface area of the atmosphere.

      My next thought was to divide my own profile surface area (maybe 1 square meter?) by the surface area of the Earth's atmosphere (500 trillion, or thereabouts) and multiply that by "tens of thousands" to come up with the probability of getting hit by a cosmic ray.

      Then I realized that the OP stated "at any given moment", and realized that you can't multiply by the number of "moments" in a flight.

      The article is complete emotional bullshit.

      • An imaginary number divided by a real number doesn't make it any less imaginary. "Tens of thousands" is a literary concept booty a scientific explanation.

      This can be read two ways. Are they trying to scare people away from planes, or impress people so they stand in front of reactors?

        The latter. It's nuke industry shilling to try to stop its inevitable decline as the market turns to cheaper and cleaner renewables.

        It's not the safety of a week maintained, normally operating reactor that is the problem. They just fixate on that because they have no answers to the real issues.

      Yes, a very slight increase in cancer risk but not necessarily attributable to radiation. Prostate cancer is a risk, evidently is from prolonged sitting (truck drivers see similar risk). The problem with tying cancers to occupational or medial radiation is that the risk factors are so small to begin with, potential correlation is often overcome by uncertainty. What we do know is the risks of these types of exposures are very very low.

      For example, you could put your bed 2 meters from a loaded spent fuel dry storage cask, and sleep there every night for 8 hours, your exposure in a year would be less that the annual exposure to where there is any observed health effect.
    • Flight attendants suffer increased risk of cancer.

      Only for skin and breast cancer.

      Skin cancer is correlated with exposure to sunlight, but not so much with radiation that can reach deep tissue.

      Breast cancer is correlated with NOT HAVING CHILDREN, something many career women do. It is also correlated with not breastfeeding, another thing that many career women do.

    • This isn't news. Flight attendants suffer increased risk of cancer. Probably because of this radiation. Astronauts have restrictions on total flight hours because of cosmic radiation.

      I always found it humorous that nuclear submariners had to wear dosimeters even though our doses were less than flight crews.

    • I can think of a number of things to put forward as a potential contributor to increased cancer risk in flight attendants.

      Kerosene fumes
      Frequent pressure changes and the effect on various vesicles and membranes
      Constant disruptions of circadian rhythms

    The guy linked above is a bit nose-in-the-air (and sort of an asshole to boot), but the playlist itself pretty much outlines a great deal about radiation, both manmade and naturally occurring.

    He's done quite a bit of work on it, and has actually taken a geiger counter on a plane to measure exposure.

    Hell, I wouldn't be surprised if some of his work was at the foundation of the article itself.

      In the same chart you get the answer:

      1 banana: 0.1 uSv

      So... 400 bananas.

          From the same chart we can also deduce see following:

          Lowest yearly dose clearly linked to increased cancer risk: 100 mSv

          This is equivalent to 2500 NY-LA flights. I think few people can accomplish that in a year.

          It sounds about as plausible as banana-eating your way to that dose; 1 million bananas.

            I don't think any can, unless someone's got a time machine. A NY-LA flight is 6.5 hours. Even if you flew constantly, you'll only get 1350 flights done in a year.

      They can't be compared. Bananas, when consumed, pass through your body and only as much potassium as required is absorbed. Your body maintains the correct level and keeps it away from areas that it could damage.

      Radiation you get on aircraft is mostly external, hitting your skin. So it's a one-off dose and mostly causes skin cancer.

      The material released from nuclear plants through accidents and bad design is stuff like Cesium. It can get into your body and sit there for decades, irradiating your organs. Unit

    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!

    • Minor correction - the earths atmosphere does far less to protect the inhabitants from radiation than the earths magnetic fields [nasa.gov]. It is common for flights to be diverted due to communication issues near the poles already. Air crews working polar routes really should have the same radiation exposure protection as any other high risk job. As should any person frequently traveling these routes.

      While stationed on the USS Arkansas (CGN 41) I used to nap directly over the reactor. I would receive less radiation there then anywhere else on the ship, and measurably less then outside in sunlight.
  • "cosmic rays or cosmic ionizing radiation, the particles are the cores of atoms, such as iron and nickel, moving at nearly light-speed."

    I especially liked that line... Sounds like something out of a comic book with evil cosmic rays that are out to get you... randomly.

    What is hard to fathom is how 5 miles of tenuous atmosphere can be better than the aluminum or steel shell of aircraft. But lets not be bothered by that.

      Tenuous? there is 11 psi difference between sea level and 35,000 feet. so a one inch deep by one inch wide column of air from the ground to 35,000 feet weighs 11 pounds. How much does a square inch of aircraft skin weigh?

      dose is about 1 mrem per hour, compared to 1 mrem per day on ground. still, only air crew have slightly higher melanoma rates than people who work on the ground as only proven effect (sunbathers, sun tanners and beach lovers are at much more risk), the danger to passengers is essentially zero.

    • it's not hard if you think about it, and lost of people have been bothered by it and putt the answer online so you can search for it. Its only YOU that can't be bothered.

      TL;DR the pressure at the rathe earth's surface is 10 tons per meter squared, so there's 10 tons of air above you, or as much stuff an a meter of steel.

    If there were substantial cancer risks due to flying, the data miners at insurance companies would have already correlated their payouts on treatments for high-frequency fliers like pilots and would be raising their premiums. Insurance companies are very much on top of cancer-causing workplaces.

    Actually I've stared in to the 'moon pool' with the the basket exposed prior to a fuel shuffle. I hardly picked up any dose at all. The water was plenty enough shield to you from the radiation of 15 year old fuel rods. The metal skin of an airliner however hardly blocks anything.

    The potassium chloride you find in most supermarkets (in water softener tablets and as salt substitutes) will expose you to about as much radiation as nuclear waste [youtube.com]. And heaven forbid you have a granite countertop in your home. The radiation detectors CBP has installed at border checkpoints are regularly triggered by mundane shipments like cat litter, granite, porcelain, bananas, nuts [wikipedia.org].
  • The atmosphere dosent protect earth inhabitants like the magnetic fields do [nasa.gov]. During solar storms, flights are already diverted due to risk of radios not working. A single polar flight has been shown to dose people with 12% of a years safe dose in a single one way trip. There should be monitoring of workers on routes near the magnetic poles, as we should monitor people who frequently (once a week) make these trips.
