Abstract

Patente de Invenção: <B>"PROCESSO PARA A DEGRADAçãO DA RADIOATIVIDADE DE UMA PEçA METáLICA"<D>. A invenção refere-se a um processo para a degradação da radioatividade de uma peça metálica. Nisso, é retirada primeiramente uma camada oxídica da peça de metal. é previsto que depois disso é retirado da solução de descontaminação um agente de efeito oxidante ainda existente. Em conseq³ência disso, é degradada uma camada do metal. Uma vez que os radionuclídeos se encontram apenas nas regiões próximas da superfície do metal, o metal residual pode ser levado à sucata normal.
