Track etch based LET spectrometry in beams of neutrons with energies from 0.2 to 200 MeV

There is still need to develop further methods able to characterize an external exposure to neutrons. This contribution presents results obtained with linear energy transfer spectrometer based on the chemically etched track detectors. There were employed two types of polyallyldiglycolcarbonates, Page and Tastrak, to obtain spectra of linear energy transfer. Detectors were exposed to monoenergetic neutron beams with energies of 0.2, 0.5, 1, 3, 7, 15, 20, 100 and 200 MeV. Calculated dose equivalents are compared with delivered reference values.
