Resumo
The subject of this study is a Peruvian painting from the 17th century, which has been recently restored and then
contaminated by mould. It received different unsuccessful treatments. Therefore, radiation process was suggested as an
alternative once it is an effective technology for decontamination and conservation purposes. The aim of this study is to
investigate the influence of irradiation process on the original painting and on the products used in the restoration
process. These products were irradiated with 60Co gamma rays applying doses in the range of 6–25 kGy. The polymeric
materials were characterized by thermal analysis techniques before and after irradiation. The colour of the pigments
irradiated and non-irradiated were compared by spectrophotometric analysis. Small samples removed of the original
painting were also irradiated and investigated. The results obtained until now allowed concluding that the irradiation
with the appropriated dose of 6.0 kGy, according to the literature, will not damage the restored painting. r 2002
