Radiation dosimeter - for fast neutrons by measuring diode photo current before and after radiation

摘要

A radiation dosimeter for fast neutrons is a silicon-p-type zone, 0.5 to 0.6 mm thick, which an n-type surface zone, 6 mu thick, i.e. thin enough to make the diode photosensitive. A luminescence diode is arranged at a certain distance so that the radiation dose can be determined by measuring the photoelectric short-circuit current across the silicon diode before and after radiation.
