This study aims to evaluate the potentially harmful effects of ionizing radiation on materials commonly used as paint layers in artworks. Two widely used protein-based binders, casein and animal glue, were examined—both on their own and in combination with lead white pigment. The binders were exposed to radiation doses typically used for treating insects and fungi in cultural heritage artefacts (2, 7, 10 kGy), as well as much higher doses (25, 100 kGy), at two different dose rates (0.3 and 27.7 kGy/h).
