Sažetak
Many objects of cultural heritage are exposed to radiation to stamp out the unwanted microorganisms that are present on them. Although it was initially considered that the radiation of painted objects was completely harmless and without any adverse effects on the object itself, later changes in the colour of pigments were noticed, some of them being bedimmed, some illuminated, etc. This paper deals with a specific area of the influence of gamma radiation on binders in paint layers, as only few articles have been published on this subject so far. Seven different binders used throughout the history of painting were chosen and prepared. The binders were applied on polyethylene substrates (radiation-resistant) and radiated with five different doses ; first in the centre and then away from the centre. After irradiation, colour changes of each of the binders were measured using a CIE Lab colorimeter.
