F\u00f6r att ta reda p\u00e5 hur man b\u00e4st kan skydda bes\u00e4ttningsmedlemmarna mot denna str\u00e5lning samarbetar ESA med ett centrum i Tyskland f\u00f6r att testa olika typer av sk\u00e4rmning, d\u00e4ribland jord fr\u00e5n m\u00e5nen och Mars.<\/p>\n<\/div>\n<p>Rymden \u00e4r fylld av laddade partiklar, vilket inneb\u00e4r att astronauter officiellt klassas som str\u00e5lningsarbetare.

Detta magnetf\u00e4lt fungerar som ett skydd mot st\u00f6rre delen av rymdstr\u00e5lningen.
