If you need even more to worry about, cosmic rays are suspected to be one, if rare, causes of chromosome and cell damage in the body.. A big problem in space, we on the ground are mostly protected - more danger when on a mountaintop or airliner. There is lots of info on the interweb for anyone interested. This is one fairly low-tech and interesting article that seems reasonably complete: https://www.vox.com/the-highlight/20...theory-science
It does say this: "...The camera in your phone works because photons — the subatomic particle that constitute light — activates a sensor at the back of the lens. Cosmic rays can activate the sensor too. (Every once in a while, too, a cosmic ray can interfere with a microprocessor and cause a computer to crash.)"
Science geeks can make their own cloud chamber and see particles that come from space. Again, a lot of info on the web. When in high school a friend designed and built a fairly large continuously operating cloud chamber for a science project. It was amazing. He was offered a job by Westinghouse!
JKJ, geeky but not a physicist
