The starting point for the reported experiment was the fact that cellulosolytic microfungi show a better growth on deteriorated paper than on paper which is well preserved. The intention was to find out if fungal biomass developed on paper can constitute a useful parameter in order to evaluate paper chemical and physical conditions. To this purpose, colorimetric measurements were carried out on paper that had been inoculated with Penicillium chrysogenum after a previous exposure to increasing ionising gamma radiation doses. It seems that there is a good correlation between the radiation dose absorbed by the paper and the values of the chromatic coordinates of the CIE L*a*b* system, b*, indicating yellowing, giving die clearest result. Collateral information from the experiment confirm that low radiation doses (up to 10 Gy), as they are needed to disinfect/disinfest paper from biodeteriogenic organisms, can not significandy damage its substrate. Authors intend to deepen this research in order to elaborate a simple and standardized method for describing the state of damage caused in paper . This method could be applied also in other fields like food irradiation to recognize a fraudulent irradiation. Copyright © Saur 2007.
