Hi:
Has the use of x-rays for telecommuncations ever been considered? I imagine that x-ray photons would have more bandwidth than visible-spectrum photons. Other than bandwidth, are there any advantages to using x-rays instead of light. One major disadvantage, is the fact that x-rays could injure humans and possible some metal equipments by knocking electrons off the atoms -- one solution to this would be to use a lower rate of x-rays photons per second so that the amount of x-ray power* does not reach the danger level.
Thanks,

*Power in this case define the amount of photons per second, not the amount of eV per photon
