As I understand, radiation therapy is basically directing highly concentrated x-rays/gamma radiation to kill tumors/cancer cells. I don’t quite get how, in this process of “shooting” high energy beams at the tumor, the skin/muscle cells don’t get damaged?
In: Biology
It’s because the soft tissue in your skin does not absorb those rays, so the rays just pass through. Look up “Liquid water absorption spectrum” since our bodies is mostly water. Low spectrum light, like radio waves, is not absorbed as well, same for high frequencies. Bones and tumors, etc, are different to skin, so they do absorb the rays.
