Attempts have been made to use nuclear track detectors in the measurem
ent of neutrons, alpha-particles and heavy multi-charged particles. Cu
rrently, some of the most important applications include the use of so
lid-state track detectors in neutron dosimetry, in radon dosimetry in
homes and in mines, and charged-particle measurements in space and of
accelerator beams used for biomedical applications. In this paper, a r
eview will be given of recent track-detector developments in the field
s of neutron and radon measurements.
