This work investigates the use of passive luminescence detectors to determine different types of averaged linear energy transfer (LET-) for the energies relevant to proton therapy. The experimental results are compared to reference values obtained from Monte Carlo simulations.Optically stimulated luminescence detectors (OSLDs), fluorescent nuclear track detectors (FNTDs), and two different groups of thermoluminescence detectors (TLDs) were irradiated at four different radiation qualities.

The radiation quality is here expressed through either the linear energy transfer (LET) or the closely related metric, which depends on the particle's speed and effective charge. The derived LET andvalues are applied to improve the dosimetry in light ion beams.
