title: Suggested interpretation of polysulfone dosemeter mathematical response.
abstract: An interpretation of mathematical response of polysulfone film dosemeters, proposed in the literature, is suggested, considering the photochemical reaction of degradation, which a polymer film undergoes when exposed to UV radiation. The function is interpreted using a highly simplified model of photo-degradation. The interpretation is aimed to stimulate further reflections on the possibility of modeling exactly the behavior of the polymer film, in order to obtain an exact calibration curve, based on physico-chemical considerations, rather than on pure empirical experience. We show that the simplified reaction scheme leads to a kinetic model described by a linear system of differential equations, which is the key aspect of the response function interpretation. The linearization is a consequence of the schematization employed, which although simple, is truly reasonable and already proposed also by other authors.
