I'd like to know some specifics about the biological effects of X-rays on living tissue. I am aware that X-rays, along with other forms of ionizing radiation, have stochastic effects of DNA but what is the data regarding the non-stochastic effects of intense X-rays? In particular, can sufficient intense X-rays cause non-stochastic damage to ribosomes as well as proteins? Are there uses for intense X-rays in radiosurgery? And moreover does the dosage of focused X-rays required to kill specific tissue masses by fragmenting biological macromolecules depend of the specific frequency and do broadband X-rays have more cytotoxic efficacy than monochromatic X-rays with a specific frequency(not to mention absorption of certain X-ray frequencies by ribosomes).
