How x-rays interact with living tissues?

As ionizing radiation of the electromagnetic spectrum these puppies can be quite interesting. These are the effects I can think of, off hand. 1. Fluorescence 2. 1. X-Rays cause certain substances to fluoresce, i.e. read more

X-Rays produce excitation and ionization of the atoms and molecule of the substances through which they pass; Excitation is the process of raising an electron to a higher energy level. Ionisation is the process in which an electron is completely removed from an atom; Biological effect; X-Rays interact with living tissue and can cause biological changes. read more

X-ray interaction with matter. Again, without going into the gory detail here, we need to know that there are two major ways in which diagnostic x-rays interact with tissue. The first is the photoelectric effect, where a photon uses up all of its energy to eject an electron from an atom; while the electron will move around and ionize neighboring atoms, there are no scatter photons. read more
