[en] Charged particles can be registered in a track etch detector (TED) when the linear energy transfer (LET) of a particle is higher than a threshold. Relative response of thermo luminescent detectors (TLDs) generally decreases with increasing LET of radiation depositing in them energy. The exposure of both these detectors in high energy charged particle beams permits to improve knowledge concerning the possibility of theirs use. Two types of poly allyldiglycolcarbonate (PADC) TED and two different TLDs have been exposed since several past years to high energy charged particles with energies up to 1 GeV/amu, and LET up to 600keV/μm in water. Some unknown ('blind') exposures were also realised. Basic results like LET spectra, relative response of TLDs as the function of LET, etc., are presented. Particular attention is devoted to the results of evaluation of both detectors after blind exposures, theirs analysis and discussion
