The most common irradiation is x-rays, used for prostate cancer or after surgery for breast cancer. The machine bombards a metal target with high-energy electrons. The electrons are so energetic that they knock electrons out of the K-shell (the one "next to the nucleus") of the target. The other electrons fall into the empty shell, and the result is an x-ray, corresponding to the energy difference between the K-shell and the one above. It 's actually light, but light that is higher in energy that even ultraviolet.
