A general term applied to parts of instruments which are designed to detect Ionising Radiation. Ionising radiations interact with the detector, the detector converts this interaction into a signal which can be amplified and interpreted by other devices. Detectors can be Passive Detectors (which require a subsequent process, e.g. chemical etching, to determine useful information), and Active Detectors (which enable real time information to be obtained, e.g. EPD).
