Os cadernos da primeira mulher a ganhar o Nobel que ficarão em caixas de chumbo por 1,6 mil anos
Continua depois da publicidade
Os itens estão contaminados principalmente com Rádio-226, um isótopo que possui uma meia-vida de aproximadamente 1.600 anos. Isso significa que, para historiadores e curiosos, o "brilho" das descobertas de Curie permanecerá fisicamente perigoso por milênios.
Proteção de chumbo e termos de responsabilidade
Atualmente, a BnF armazena essa coleção em caixas especiais revestidas de chumbo para conter a emissão de partículas. O acesso é restrito. Pesquisadores que desejam consultar os originais precisam utilizar vestimentas de proteção, luvas e máscaras. Além disso, é obrigatória a assinatura de um termo de responsabilidade, reconhecendo o risco no manuseio dos documentos.
Marie Curie, a primeira pessoa a ganhar dois prêmios Nobel em áreas distintas, no caso dela em Física e Química, não tinha plena consciência dos efeitos biológicos da exposição prolongada à radiação. Relatos históricos indicam que ela costumava carregar tubos de ensaio com elementos radioativos nos bolsos do jaleco e os guardava em gavetas de sua escrivaninha, maravilhada com a "luz suave e fantasmagórica" que eles emitiam no escuro.

Morte de Marie Curie
A exposição constante resultou na morte da cientista em 1934, vítima de anemia aplástica. A contaminação se estendeu para sua mobília e até para seus livros de receitas culinárias, que também são mantidos sob custódia especial na França.
Para contornar o risco e democratizar o acesso, a Biblioteca Nacional da França e outras instituições, como a Wellcome Collection em Londres, iniciaram processos de digitalização. Através de versões online, é possível examinar os diagramas, fórmulas e anotações de Curie sem a necessidade de ir até o local e utilizar trajes especiais.
