Spectrometry of the linear energy transfer in high energy reference fields

Measurements of the high energy reference fields established behind the shielding of accelerators at CERN, Geneva, and JINR, Dubna, were made using a Linear Energy Transfer (LET) spectrometer based on a chemically etched track detector. The experiments demonstrated the wide capabilities of this microdosimetric technique. The LET spectra are in a reasonable agreement with those obtained by means of a tissue equivalent proportional counter. The integral values of the dosimetric characteristics calculated from the LET spectra also approach closely those obtained by other dosimetric and microdosimetric methods. (P.A.)
