ABSTRACT:
A spectral dosimeter for detecting both the fluence and the energy spectrum or ionization density spectrum of high energy radiation comprising multiple MOS capacitors on a single semiconducting integrated circuit chip which collect ionization charge generated by high energy particles passing in the vicinity of the individual capacitors. The capacitors are individually read by comparison with reference capacitors. The capacitors are fabricated or operated such that varying amounts of collected charge will cause the capacitors to be read as having collected a threshold amount of charge.
