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.
