| radiation detector which reveals optical defects produced by ionizing radiation in the material constituting the detector
Note 1 to entry: For example, the track etch detector is a neutron radiation detector consisting of a light plastic material (e.g. CR39) in which the incoming radiation physically displace the nuclei of that material.
Note 2 to entry: The observation of the tracks of the incoming particles by etching allows the establishment of a relationship between the number of tracks and incoming particle fluence.
Note 3 to entry: This entry was numbered 394-24-09 in IEC 60050-394:2007.
