I know that X-rays can be detected by various ways, like ionizing of air particles.

Is there a way to detect X-rays,which are photons, by detecting ? Can something absorb the energy of the X-rays and detect if it is there?

Photoelectric effect........?? –  Mr.ØØ7 May 15 '13 at 8:13

@007 how does it work and how to you apply practically to detect X Rays? –  owlp May 15 '13 at 8:35

I think when X-rays will target the metal piece electrons will be ejected to start a photo-current . What say? –  Mr.ØØ7 May 15 '13 at 8:37

It depends what you want to detect. Film detects them, as you must know . Geiger counters: geigercounters.com/AboutGgr.htm . If you want to measure the spectrum a more complicated experiment is necessary. see also wiki en.wikipedia.org/wiki/X-ray_detector –  anna v May 15 '13 at 8:39

Photo-electric effect (i.e. photo-ionization). Photo-dissociation of chemical bonds. Exciting atomic electrons to higher states. Transferring energy and momentum to conduction electrons. Diffraction and reflection of coherent effects over many photons (though they are better handled in the field picture). Everything you study that involves light. –  dmckee May 15 '13 at 13:45

Xrays are photons, so as suggested in the comments above, the photoelectric effect could be exploited by using an appropriate material.

For example, SAXS (Small Angle XRay scattering) machines use many kinds of Si based detectors.

Medicine uses X-rays continuously and the way it detects them is by exposing film that is kept in a dark container. Thus one disallows visible light contamination.

If you do not know the source of the photons and want to see how hard they are you can expose film sequentially in a dark container covered by different materials, with different attenuation lengths and measure the energy.

X-rays and gamma rays can be detected by using a scintillation detector.

Can you maybe improve your answer by extending the explanation about scintillators, preferably including nice references/links? –  Bernhard Jul 15 '13 at 17:44
    
Dear Bernhard, The scintillation detector comprises of NaI (Tl) crystal (scintillator) fixed tightly on a photomultiplier tube in a Gamma Ray spectrometer. For detection and measurement of gamma rays one inch or more thick scintillator in used. For X-rays thin scintillator is used. Portable Geiger Muller counter is used to know gamma radiation levels from sources like Cobalt-60.
