    Space Radiation Doesn't Seem to Be Causing Astronauts to Die from Cancer, Study Finds:

    By Rachael Rettner 2 days ago Human Spaceflight

    Outer space is a notoriously harsh environment, exposing astronauts to high levels of radiation. And radiation exposure can increase cancer and heart disease rates in earthbound humans.

    But a new study has some good news: Space radiation doesn't seem to increase astronauts' risk of death from cancer or heart disease, at least not at the doses they experienced during historical missions. Still, longer missions — such a mission to Mars — will likely come with much greater radiation doses that could pose larger health risks, the authors said.

    Space travel exposes the body to higher levels of ionizing radiation than those typically experienced on Earth. And at high doses, that radiation has been tied not just to cancer and heart disease, but to a host of other health problems as well.

    Interesting results to say the least....

    But, [1] Are these studies too small for any valid conclusion to be arrived at? [2] Most of these would be from the ISS, so are the studies any indication of radiation further from Earth and/or for longer periods?

    The statistical methods used are also quite tricky. Not to mention the fact that the study was retrospective. The effects of ionizing radiation exposure to human health becomes evident after decades, and this an additional confusing factor.
    In any case, the effects does not appear to be THAT dramatic, which is good

    not quite sure what the big mystery is
    there is significant research coming out along with government regulations

    https://flightsafety.org/asw-article/radiation-exposure/
    https://www.eurocockpit.be/positions-publications/protection-ionizing-radiation
    https://www.caa.co.uk/Our-work/About-us/Aircrew-exposure-to-cosmic-radiation/

    i have read several official reports published on the net
    i have also read several government aviation pages on the subject.
    there is no grey area.

    Total number of astronauts is a very small sample size

    This rhetorical statement reads disingenuously

    Yep, agreed. Still a manned Martian trip will be daunting to say the least and there is heaps of preparational work to be done to insure the Astronauts safety, to the best of our technological know how.

    Do you hear that? It's the sound of one more of Fat Freddy's spurious arguments crashing and burning.

    He'll claim that:
    1) It only applies to astronauts in low Earth orbit, because no one ever went to the Moon.
    2) It's ALL A CONSPIRACY and NASA falsified the study!
    3) Sure, the study is true, but that doesn't mean anything.

    I am going to go with 1). Anybody want to make a bet?

    Can we send cancer patients up there to see if it cures them?
