Legado nuclear: os níveis de radioatividade em Chernobyl e Fukushima

Os desastres nucleares de Chernobyl e Fukushima tiraram inúmeras pessoas de suas casas e suas vidas. Tudo ficou para trás. Isso pode explicar porque tantas pessoas optam a voltar para as áreas já categorizadas como “limpas”. Essa limpeza é oriunda da descontaminação feita pelos governos da Rússia e do Japão, e que não é tão efetiva quanto deveria ser. Áreas já descontaminadas podem receber mais radiação trazida pelo vento, por exemplo. A herança radioativa continuará por muito tempo naquelas terras.

O projeto Nuclear Legacy, de Greg McNevin junto do Greenpeace, une dados de níveis de radiação com fotografias de longa exposição.


Campo de arroz em Fukushima, Japão

Usando um bastão de LED ligado a um Geiger counter (equipamento que mede níveis de radiação), McNevin caminhava em frente à câmera que fotografava em longa exposição, posicionada em áreas afetadas. O equipamento de medição transforma os dados captados numa resposta no display de luz, mostrando os níveis através de cores.

As cores dos gráficos de barra gerados nas imagens correspondem aos níveis de radiação encontrados. O branco demonstra níveis mais baixos de radiação, o laranja e o vermelho apontam níveis críticos.

A proposta do projeto não é científica, e os autores informam que seus resultados são “meramente artísticos”.

A special light painting tool displays radiation levels in real-time at a school in Starye Bobovichi. Here white light shows contamination levels between 0.16uSv/h and 0.26uSv/h. 30 years after the 1986 Chernobyl nuclear disaster, the schoolyard still contains areas of elevated radiation levels.

The forest has been decontaminated, but authorities only do 20 metres in from the edge, with everything beyond falling under the responsibility of a separate government agency. Forest beyond the 20 metre boundary is not decontaminated, leading to constant re-contamination of the lower forest and house that borders it. Here we see radiation levels between 0.97uSv/h and 1.4uSv/h, with yellow showing spots elevated above the government decontamination target of 0.23 uSv/h, and red showing above 1uSv/h.
