Resumo
Glass-based photographic materials are commonly found in historical cultural heritage collections.Inadequate
storage conditions for these materials lead to problems of biodeterioration, mainly by fungi.
Processing by ionizing radiation with electron beam has a biocidal effect to combat fungal contamination.
However, a known undesired effect on glassy materials is increased opacity which affects
the readability of images on photographic glass negatives.
In this way, the study proposes a methodology to minimize the darkening effects of the glasses that
are subjected to irradiation.
For this work, glass samples were subjected to irradiation with electron beams at doses of up to
25 kGy, under different controlled temperature conditions, and the effects analyzed by UV-visible
spectrophotometry and colorimetry analysis.
