“…It has been extensively studied in several countries and considered as a potential dosimetry system that may substitute the Fricke dosimeter as a reference dosimeter (Regulla et al, 1982(Regulla et al, , 1983(Regulla et al, , 1985Onori et al, 1990;Olsen et al, 1990;Kojima et al, 1993;Feist et al, 1993 ). The merits of an alanine-based dosimetry system are a very wide dose range, high stability of the radiationinduced radicals in alanine and non-destructive readout with good repeatability, so that it can be used for archival purposes.…”
