Melanin is an effective absorbent of light; the pigment is able to dissipate over 99.9% of absorbed UV radiation." https://en.wikipedia.org/wiki/Melanin https://en.wikipedia.org/wiki/Melanin "Radiative relaxation quantum yields for synthetic eumelanin" https://pubmed.ncbi.nlm.nih.gov/15068035/ https://pubmed.ncbi.nlm.nih.gov/15068035/

Near ionizing and up have non thermal effects, RF's much lower photon energy's only known action is thermal which requires orders of magnitude more power to create enough heat to damage DNA.
