Not saying there isn't a risk, but I'd rather read about measurements from a large transport type plane with the normal multilayer thick wind screens.

LA Times article lays out the research results a little better, but reading the conclusions, it isn't clear what brings on the higher mortality rate for pilots vs cabin crew:

Melanoma risk is higher for flight crews that work at 40,000 feet - LA Times
Exactly. Plastic (plexiglass) doesn't stop UVa.

GLASS significantly reduces it.

My son just graduated from UVa (University of Virginia)?

AC120-61A:

The recommended occupational exposure limit for ionizing radiation is a 5-year average effective dose of 20 millisieverts per year, with no more than 50 millisieverts in a single year.
One could fly 40 round trips between JFK and DXB and not hit 20 mSv of ionizing radiation exposure, even cruising at FL450 on every leg.

Ionizing radiation, however, is not the same thing as UVa and UVb rays...

And let's not forget what Delta-particles can do to a man.

This study stinks.

Oh, by the way... Ebola is going to run over the USA.

Yeah. Funny how we don't hear about the Ebola apocalypse now that the midterms are over.

Regarding radiation. I slather the sunscreen. And cover the windows with as many shades as possible -- both installed (totally inadequate on Boeings) and improvised.

If you see a shadow, you're getting irradiated.
