title: [Influence of regenerating and evaluation procedures on the supralinear behavior of LiF thermoluminescent dosimeters].
abstract: Measurements with LiF dosimeters in the absorbed dose range up to 6 Gy have shown a strong influence of the annealing and reading procedure on inset and extent of the supralinearity. With this regard three TLD readers and two annealing procedures have been investigated. The results are explained by a theoretical model which takes the formation of vacancies by hydroxyl ions into account. A slight effect of the LET is also observed. Since a straight line fit to the measured dose dependent deviations from linearity is possible, a quadratic equation for the calculation of correct absorbed dose values could be derived.
