O QUE SIGNIFICA VAN ALLEN BELT EM INGLÊS
Cinto de radiação Van Allen
Um cinto de radiação de Van Allen é uma das pelo menos duas camadas de partículas enérgicas carregadas que são mantidas no lugar do planeta Terra pelo campo magnético do planeta. Os cintos se estendem de uma altitude de cerca de 1.000 a 60.000 quilômetros acima da superfície em que os níveis de radiação da região variam. A maioria das partículas que formam os cintos é pensada para vir de vento solar e outras partículas por raios cósmicos. Os cintos são nomeados após seu descobridor, James Van Allen, e estão localizados na região interna da magnetosfera da Terra. Os cintos contêm elétrons energéticos que formam o cinto externo e uma combinação de prótons e elétrons que formam o cinto interno. As correias de radiação também contêm quantidades menores de outros núcleos, tais como partículas alfa. Os cintos colocam em perigo os satélites, que devem proteger seus componentes sensíveis com blindagem adequada se sua órbita gasta um tempo significativo nas correias de radiação. Em 2013, a NASA informou que o Van Allen Probes descobriu um transiente, terceiro cinto de radiação, que foi observado por quatro semanas até ser destruído por uma poderosa onda de choque interplanetária do Sol.
definição de Van Allen belt no dicionário inglês
A definição de cinto de Van Allen no dicionário é uma das duas regiões de partículas carregadas acima da terra, a interna que se estende de 2400 a 5600 quilômetros acima da terra e a externa de 13 000 a 19 000 quilômetros. As partículas carregadas resultam de raios cósmicos e estão presas pelo campo magnético da Terra.
