Almost.Gorilla said:Guys, don't confuse UV radiation (sunburn) with cosmic/solar radiation. UV is light, photons, and is easily blocked with sunscreen or most plex windows. Look at the thin sunglasses which block "100 UVA/UVB"... they're not exctly NASA materials.
Cosmic rays are another matter, a mix of energetic particles, and electromagnetic radiation of a MUCH higher frequency and energy. Think X-rays. Strong X-rays go through solid materials, then whack your body, before exiting the other side. On their way through, they cause cellular and chromosomal damage.

Just to be real nerdy: uv, x-rays, visible light, cosmic radiation, radio, etc. are all just names for slices of a continuum of electromagnetic energy propagated by photons at different frequencies. Different frequencies convey different amounts of energy (higher frequency=higher energy). Therefore they each interact differently with the human body.
Don't even get started on what a particle is...
And no, I don't wear sunblock in the plane. I probably should.
All good reasons why the mandatory age 60 retirement age should remain...even better drop it down to age 55Gorilla said:Cosmic rays are another matter, a mix of energetic particles, and electromagnetic radiation of a MUCH higher frequency and energy.

Good point.Gorilla said:To continue along the dork fork, cosmic rays are both accelerated particles and EM radiation.

The different nuclei, nucleotides, and other itty bitty missiles have different abilities to penetrate and cause damage. I honestly have no idea what danger particles pose to an aircrew as opposed to EM radiation like X and gamma rays; probably not a lot.
Anyway, dosimeters carried by pilots reveal that indeed, we are getting whacked with significant radiation.
