    My friends and I are working on a project for Uni, and we took apart a Safety Siren Pro Series HS71512 3 Radon Gas Detector to study the components inside it.

    We have managed to identify all the components apart from one. This was in the main detection chamber of the device - we believe it to be some sort of Scintillation Cell, but cannot be sure.

    Pictures have been attached of the component in question - it's the small shiny black square thing, on top of the large green square. The whole thing is stored in the black plastic box, that we believe to be the ionisation chamber.

    Our theory is that the radon particles ionise the air the chamber, and the ions are detected by this black square somehow. We just aren't sure what this square is, or how it detect ionised air particles (if it does at all).

    Would really appreciate it if someone could identify what it is and let us know. Thanks :)
