Let's not have an irresponsible attack on science and scientists
"Yet NIOSH offers an out, as if to immunize airlines from lawsuits: "If you are exposed to cosmic ionizing radiation and have these health problems, we can’t tell if it was caused by your work conditions or something else.""
As if Trump wasn't bad enough, someone else's scientific literacy is in serious doubt.
NIOSH is simply acting responsibly in a scientifically literate manner. Specifically, correlation does not equal causation.
Everyone who has studied even basic introductory statistics knows that correlation does not equal causation. You need additional studies.
The cosmic electromagnetic radiation flight crews are exposed to goes up with hours flown. But so does the exposure to aircraft-base electromagnetic radiation. And so does exposure to carbon monoxide and other cabin fumes. And by traveling more, so does crew geographic exposure to strange foods, strange water, strange bacteria and viruses. More traveling means more time on a flight attendants feet, which can affect pregnancy.
Let us not attack NIOSH for simply stating scientific fact. Dozens of other factors tend to go up when hours flow, distance flown and average flight-time increase. Without further scientific investigation, nobody can simply pick out one and say it is responsible for the effect seen, not Donald Trump, not members of the news media.
