The development of the solid state nuclear track detector CR-39 as a microdosimeter for high-energy neutron cancer therapy is given. The irradiation, etching and readout procedures are described and measured track size distributions are presented. The mathematical basis for converting a track size distribution to a microdosimetric spectrum is explained, and microdosimetric spectra as measured using both CR-39 and a tissue-equivalent Rossi-type proportional counter are compared.
