[en] Heavy charged particle-to-gamma relative efficiencies calculated with modified track structure theory (MTST) for individual peaks in TLD-100 are calculated and compared with recent measurements at intermediate energies by Massillon-JL et al. [2006a. Observation of enhanced efficiency in the excitation of ion-induced LiF:Mg,Ti thermoluminescent peaks, J. Appl. Phys. 100, 103521-103525; Erratum: Observation of enhanced efficiency in the excitation of ion-induced LiF:Mg,Ti thermoluminescent peaks [J. Appl. Phys 100, 103521 (2006)], J. Appl. Phys. 102, 079901, 2007]. The influence of input functions that enter the model is investigated. Two types of radial dose distributions, analytical and Monte Carlo, are used as well as two types of supralinearity functions, f_δ(D), measured for test radiations taken as ⁶⁰Co and 8.1 keV X-rays. Theoretical efficiencies are more sensible to the choice of test radiation than to the choice of dose profile. MTST efficiency values obtained with 8.1 keV X-rays f_δ(D) give a good description of TLD-100 data for peaks 5, 6a, and 7 at intermediate energies
