Resumo

Durante o tratamento de conservação, a maior ameaça aos objetos arqueológicos de madeira saturada de água (WAW) é o colapso e/ou contração, que podem ocorrer durante o processo de secagem. Trabalhos recentes realizados pelo projeto CuTAWAY revelaram, utilizando micro-tomografia computadorizada (micro-CT), que a extensão das alterações estruturais adversas encontradas internamente nos WAW conservados era muito maior do que o geralmente previsto. Sugerindo a necessidade de os conservadores monitorizarem e avaliarem a condição interna dos WAW antes, durante e após o tratamento. Neste estudo, verificou-se que a imagem por raios X oferece uma alternativa mais rápida e amplamente disponível à micro-CT. Embora as imagens tenham uma resolução inferior às obtidas por micro-CT, permitiram identificar a grande maioria dos danos internos presentes numa série de amostras durante várias etapas do tratamento. No entanto, a interpretação correta dos danos internos nas imagens de raios X requer um conhecimento prévio do material lenhoso.
