X rays used in the space or other planets[edit]

I'm guessing this a reference to the potential for interstellar communication using X-rays. However, this is just theoretical at the moment. NASA has tested X-ray communication systems, but only between Earth and the ISS. 2A00:23C7:99A4:5001:3533:7B73:616:5C0 (talk) 00:44, 10 July 2022 (UTC)[reply]

Wiki Education assignment: Technical and Scientific Communication[edit]

I am a student editor doing a project for my Scientific Communication class. Through my research I have done for the past few weeks I have added contributions about X-ray harm. I think that is a very common worry for patients and on this Wikipedia page there should be more information about it. — Preceding unsigned comment added by Sthomason27 (talkcontribs) 12:58, 5 October 2022 (UTC)[reply]

Mathematical inconsistency[edit]

The introductory paragraph says that X-rays have a frequency range of 30 PHz to 30 EHz, so that the limit frequencies are a factor of 1000 apart. Since photon energy is directly proportional to frequency, X-rays should therefore cover a range of energies with a 1000-fold difference between the highest energy and the lowest energy.

However, the energy range given for X-rays in the same paragraph is 145 eV (electron volts) to 124 KeV; the extremes differ not by a factor of 1000, but of approximately 855.

WolframAlpha says that 30 PHz corresponds to a photon energy of 124 eV, not 145 eV. Should I therefore change the lower energy limit of "145 eV" to "124 eV"?
