We take a look at how the main detectors in use today work. First, let's recall that a detector is generally an electronic device that translates its sensitivity to radiation by delivering an electrical signal (1) .
there are passive detectors that reflect their sensitivity to radiation in other ways, which we won't go into here: modification of optical density (photographic emulsion), physico-chemical (tracketch), structural (radiation damage), and so on.
The interaction process exploited in this case is that of generating "free" electrical charges, the precursors of the signal. The interaction of radiation with atomic electrons can lead either to the ionization of matter, i.e. to the direct generation of "free" charges, or to the generation...
