Discussion Overview

The discussion revolves around the capability of Light Dependent Resistors (LDRs) to detect X-rays, particularly in the context of creating an X-ray detector for bounce back conditions. Participants explore the theoretical and practical aspects of this detection method.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires whether LDRs can detect X-rays and expresses a need for assistance in building a detector.
  • Another participant clarifies that LDR stands for light dependent resistor and questions the manufacturer's specifications regarding X-ray detection.
  • Some participants suggest that LDRs might detect X-rays under certain conditions, but express concerns about their sensitivity being low.
  • One participant mentions the use of semiconductor crystals for X-ray detection, explaining how electron hole pairs are formed and how this can be useful for material identification through X-ray fluorescence.
  • Another participant notes that since X-rays and light are both electromagnetic waves, there may be a possibility for detection, and expresses intent to test the device.
  • It is mentioned that LDRs, typically made from CdS, could respond to X-rays, albeit not efficiently.
  • A participant raises the idea of using phosphor coatings found in fluorescent lights or CRTs as an alternative detection method.

Areas of Agreement / Disagreement

Participants express varying opinions on the effectiveness of LDRs for X-ray detection, with no consensus reached on their viability or efficiency. Multiple competing views regarding detection methods and materials are present.

Contextual Notes

Participants do not provide definitive conclusions about the conditions under which LDRs might detect X-rays, nor do they resolve the efficiency concerns raised. The discussion includes assumptions about the properties of electromagnetic waves and the materials involved.

Who May Find This Useful

Individuals interested in the development of X-ray detection devices, those exploring the properties of LDRs and semiconductor materials, and researchers in the field of experimental physics may find this discussion relevant.

Can LDR detect the X-Rays? Please help me. If it does, I have to make the x ray detector for bounce back conditions.:confused:

Does LDR stand for light dependent resistor?
What does the LDR manufacture say about X-Ray detection?
 
I guess it can, if you have a lot of x-rays. I think the sensitivity would be rather low though.
 
I've seen it done with semiconductor crystals where the x-ray forms electron hole pairs. If the incidence of photos striking is low enough, the energy of the photon can be determined by the amount of charge released. This is handy when determining the material types by X-ray fluorescence
 
Because X-Ray and Light are both Electromagnetic waves. Thank you very much. I'm going to test that device.
 
LDRs are generally CdS, a semiconductor, so yes they probably will respond to X-rays but not very efficiently.
 
Have you tried any of the various phosphor coatings use in florescent lights or CRTs?
