The goal of this research is to develop the solid-state nuclear track detector (SSNTD) CR-39 as a neutron dosimeter for in vivo measurements of neutron doses in fast neutron radiotherapy. The dosimetry system (track area analysis system), consisting of CR-39 detectors and an automatic image analyzer, is analogous to a pulse-height analysis system using an ion chamber and a multichannel analyzer. By following simple procedures, which are common practice for pulse-height analysis systems, a track area analysis system should produce consistent results. This paper describes the effect on the measured CR-39 sensitivity of varying track-counting parameters that most nearly reproduce the sensitivity reported previously for manual track counting.
