Hair and nails are generally less sensitive to radiation compared to other parts of the body. However, it's important to note that all cells in the body can be affected by radiation exposure to some degree.
The visible spectrum is the part of the spectrum that we can see with our eyes. It ranges from approximately 400 nanometers (violet/blue) to 700 nanometers (red). This is the range of wavelengths of light that our eyes are sensitive to.
It all depends on the organs. Those cells, tissues and organs, where theres lots of division are most sensitive to the harmful effects of radiation at high levels of exposure, including the skin, the gut mucosa, hair follicles and so forth...
The name of the light-sensitive pigment in rods is rhodopsin.
Physically, it's usually the genitals -- primarily the testicles. These are the parts that hurt like heck if you kick a guy in the crotch. During sex though, it's the erect penis. Different parts of the penis are sensitive on different guys. For some of us, it's the underside, for others it's the tip. For some guys it's the very base of the penis, right where it joins the rest of the body. (There are exceptions, of course -- everybody's different.) Emotionally, a guy's most sensitive part is just like a girl's -- it's the heart. We're just more likely to hide the pain!
