"When a photon interacts with a cell, it has a certain (small) probability of causing a carcinogenic mutation." I'm also no expert, but surely there is a risk of more significant, irreparable genetic damage accumulating if several photons interact with the same skin cell, as opposed to those same photons interacting with several different cells throughout the body?
