Passive Radiation Detector
Published: Oct 12, 2018
A passive detector is a device, usually in the form of a Dosimeter, which is used to measure levels of Ionising Radiation exposure. An example includes the Film Badge and the Thermo Luminescent Dosimeter (TLD). The detectors are passive because they need to be 'read' at a later stage in order to ascertain the level of exposure recorded. See Active Detector which can provide real-time information.
