 * 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)

Wiki Education assignment: Technical and Scientific Communication
— Assignment last updated by Brennam29 (talk) 15:21, 21 September 2022 (UTC)

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 (talk • contribs) 12:58, 5 October 2022 (UTC)

Mathematical inconsistency
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"?

"Energy Ranges": X-Rays Vs. Gamma Rays
I wonder if it would make sense to consider X-Rays to be a low-energy form of gamma rays.

Just as the color red is a low-energy (long wavelength) form of visible light, might not X-Rays be a low-energy "color" of gamma rays?

I would be very interested in any thoughts upon this matter... The Grand Rascal (talk) 07:10, 1 May 2024 (UTC)


 * There is absolutely no physical reason to have different names for x-rays and gamma rays - and also IR, UV, etc. All these are either historical terms or are specific to human physiology. In any case, Wikipedia isn't the entity to introduce new terms... Evgeny (talk) 09:04, 1 May 2024 (UTC)
 * Cool thanks for sharing this info to me 😁 222.153.163.70 (talk) 08:36, 16 May 2024 (UTC)
 * The appropriate Wikipedia policy WP:COMMONNAME: "...the name most typically used in reliable sources is generally preferred." --ChetvornoTALK 16:07, 16 May 2024 (UTC)

X-ray emission from diodes?
Hi, vaguely recall a discusson about using a vacuum encapsulated silicon diode driven far beyond avalanche breakdown generating a stream of electrons that were later used as "the E-beam source for a CRT" but have heard no more about it. With the advent of vacuum ultraviolet (160nm) LEDs it might be worth investigating if such a device can be leveraged to create a new X-ray source with some modifications. In this case the drift velocity seems to be a critical factor so such a source would also be monochromatic which is desirable for physics and engineering applications. A possible device would use a helium (low mean free path) fill with such a diode, accelerating electrons from the VUV chip recombination region using a micro-piezoelectric transformer and pulse forming network onto a low work function (likely Sr, Mg or Ba) electrode for the actual X-ray emission to occur. This might actually work with some early UV-C LEDs notably the TO-5 variety as they have an open structure. It would potentially only need 4KV internally which would be unprecedented. 91.190.161.160 (talk) 04:55, 8 June 2024 (UTC)
