Hell. The sun, other cosmic rays, and the various Earthborne types of decay radiation are downright unhealthy compared to that lens!
As a nuke mechanic on subs, I got less exposure when submerged than I did as a civilian driving to work every day in Southern California and living in a 100-year-old house.
Your average Joe or Josephine gets about 300mRem per year from various sources. I think the most exposure I ever got while aboard was not even 40mREM in a year, and this year included a reactor shutdown and a good deal of work in the Rx compartment itself. That is considered well within limits for the Navy, but still relatively high, due to the work in close proximity to the Rx itself. Most of our exposure is from betas that come from the decay of Co-60 that gets lodged in low points in the system or around junctions, pumps, valves, etc. That C-60 is created when the stable Co-59 is impacted by a particle ejected into the primary coolant from the fuel itself. The Co-59 gets into the coolant due to wear. (Valve seats, etc.) So, as you can see, it takes a lot to cause the primary source of exposure for us. Much more than it takes to just get hit directly by sunlight.
