… hides, the effect was largely detrimental for chrome-tanned leathers, suggesting photodegradation of collagen crosslinks. Further extending the investigation of environmental stressors, the effects of gamma irradiation on tanned leather have been studied too (Department of Physics, Egerton University, Egerton, Nakuru, Kenya et al., 2024). Their work showed that low to moderate radiation doses could enhance the mechanical stability of leather, particularly in vegetable-tanned samples, due to new molecular interactions. However, at higher doses, degradation effects became dominant, especially in chrome- tanned samples. The choice of tanning …
