[en] The radiographic methods are important in the scientific inquiry of the art and archaelogic works throughout the world. In Brazil, this study has been realized at a few biological research groups and no more development can be recognized. By the radiographic analysis of six oils on canvas assigned to Ataide (Manuel da Costa Ataide), an impressionist painter of the 18th century, the authors try to determine his main technical pattern (distribution of heavy metal pigments, application of thick layers of pigment, etc.). The basic compositional elements were evaluated along with chemical tests and analysis by ultraviolet and infrared radiations, representing a historic document about Ataide's style. Each technique will be related to the purpose of the inquiry, affording the authors the opportunity to offer comments upon restoration, conservation and authentification of paintings. (author)

As tecnicas radiograficas constituem um metodo importante na investigacao cientifica das obras de arte e objetos arqueologicos, sendo amplamente utilizadas em outros paises. Por meio da analise radiografica de seis pinturas atribuidas a Ataide (Manuel da Costa Ataide), pintor mineiro do seculo XVIII, responsavel por obras de estilo barroco presentes nas igrejas mineiras, procuramos documentar suas principais caracteristicas tecnicas (uso de pigmentos de chumbo, padrao de pinceladas, etc.). Esses dados foram associados a informacoes obtidas do estudo bioquimico dos seus elementos componentes e da analise com radiacao ultravioleta e infravermelha, constituindo um documento historico do estilo proprio de Ataide. A correlacao com o padrao tecnico utilizado na construcao de outras obras conhecidas do autor (em numero restrito) possibilitou a devida autenticacao. Obtivemos, tambem, informacoes que possibilitaram a realizacao de um adequado processo de restauracao das pinturas e de uma imagem em madeira policromada de autor desconhecido. A originalidade deste trabalho consiste na adaptacao e aplicabilidade de um estudo dessa natureza as condicoes do nosso meio. O estudo radiologico das telas de Ataide faz parte de um projeto de pesquisa, coordenado por profissionais da Escola de Belas Artes da UFRJ, com o objetivo de construir um relato historico do seu estilo artistico. Este importante pintor mineiro deixou poucas obras 'assinadas', dificultando, assim, a caracterizacao mais detalhada do seu padrao tecnico. Varias telas sao consideradas de sua provavel autoria, nao havendo, porem dados cientificos que permitissem a autenticacao. (autor)Journal

[en] The paper reviews briefly the application of gamma radiation to preservation of cultural objects for disinsectization, disinfection and strengthening of materials such as wood or stone by impregnation with a liquid resin and in situ polymerization. As heavy equipment is required two facilities are specialized a 1000 T Bq cobalt 60 source at Grenoble (France) and 100 T Bq one at Rostoky (Czechoslovakia). Examples of treated objects are given

On passe en revue l'application du rayonnement gamma a la conservation des biens du patrimoine culturel pour la desinsectisation, la desinfection et: - la consolidation des materiaux degrades tels que la pierre, ou le bois, par leur impregnation avec une resine liquide radiopolymerisee in situ. La mise en oeuvre de ces techniques necessitant des equipements lourds, il y a deux installations: a Grenoble (ARC-Nucleart) et a Rostoky (Tchecoslovaquie) de 1000 T Bq et 100 T Bq respectivement. On donne des exemples d'objets traitesJournal
[en] The disinfection, or decontamination, of cultural heritage artefacts by means of irradiation has been discussed extensively in the previous chapters. In this chapter, more pragmatic information is given to help choose the right methods for disinfection. Some fundamental aspects are discussed briefly in the form of questions and answers so that the reader may become more familiar with the terminology.

[en] A brief introduction into the title topic, concentrating on the history of the efforts worldwide and, in particular, in Czechoslovakia (or today's Czech Republic). Specifically named are the Nuclear Research Institute at Rez, Prague Institute of Chemical Technology, Central Bohemian Museum at Roztoky with its irradiation facility, and the Central Institute for Isotope and Radiation Research in Leipzig, Germany.
