Abstract

A dosimeter for radiation fields is described. The dosimeter includes a scintillator a light pipe having a first end in optical communication with the scintillator and a light detector. The light pipe may have a hollow core with a light reflective material about the periphery of the hollow core. The dosimeter may further include a light source that generates light for use as a calibrating signal for a measurement signal and/or for use to check the light pipe.
