Resumo
The great interest in the development of research involving ionizing radiation
aims to significantly increase the conservation of the skins of taxidermized animals, both
for scientific collections and on display, causing their infection and disinfestation, without
altering their originality, reducing the use of chemical products, presenting a safe and
efficient technology. The preservation of taxidermied mammals has been widely used for
educational, scientific and Museum display purposes. However, prolonged exposure to
environmental factors or the excessive use of chemicals to store these materials in the
collection can affect the integrity of the skin of these animals. In this study, we investigated
the effects of gamma radiation on the structure and composition of the skin of
taxidermied mammals, with the aim of contributing to a better understanding of
conservation processes and the potential risks they may entail. Taxidermy is an animal
preservation technique that has been used for centuries, allowing specimens to be
arranged in their natural form and/or preserved for scientific studies. Samples of skin
from animals from the Brazilian flora were selected, deer, coati, prawn and bison, and
these samples were irradiated at doses of 1, 3, 5, 10 and 15 kGy. After gamma irradiation,
they were characterized by colorimetry, scanning electron microscopy (SEM), optical
microscopy (OM), infrared microscopy (FTIR) and mechanical analysis. The results show
that the doses of gamma irradiation that the samples were subjected to did not
compromise their physical and chemical integrity. This indicates the possibility of using
gamma radiation for disinfestation and disinfection.
