    Recently I've overheard at least three people talking about how bad bananas are because they are radioactive- is this true or are they just saying it....

    Everything is radioactive to an extent, so yes, they are correct, but it's nothing to worry about. You'd be just as correct to say that the carpet is radioactive.

    They are radioactive because of their potassium content, but it's not harmful.

    You get a higher radiation dosage from a single X-ray than you'd get from eating a thousand bananas. And the X-ray is totally safe. I'm not sure what the leathal dosage is for eating bananas but I expect the potassium overdose would kick in long before radiation poisoning would.

    Thanks guys. And how bad are planes for radiation? Like, travelling in one for eight hours?

    This would be comparable to an X-ray, meaning it's harmless.

    famously, eating a banana exposes you to a higher level of radiation than living for a year on a nuclear power plant.

    It's pretty safe, you do suffer an increased exposure to cosmic radiation the higher up you go, but it's probably comparable to spending a day out in the hot sun.

    The only time to worry about this is if you are pregnant then probably best to avoid planes to prevent exposure to the unborn child.

    As for the Bananas, I once heard that you have eat about ten thousand before you receive the same kind of exposure as a chest x-ray. Not something to worry about. Higher risks in life to worry about.

    I've found a league table of radioactive food.

    Bananas are #3 which means they're not the oxbridge of radioactive foods - probably somewhere in the Russell group

    X-rays are reasonably safe if you're only exposed as often as the average layman. Dentists, radiologists, and others who stand to be exposed to them daily have to take special precautions, since the rads will begin to build up.

    Not if your lunchbox contained a banana. :banana2:
