En af disse er str\u00e5ling: en usynlig fare, der dog kan for\u00e5rsage alvorlig skade p\u00e5 rumrejsende.

Str\u00e5ling beskadiger de celler, som vores kroppe best\u00e5r af, og kan for\u00e5rsage alvorlige sygdomme \u2013 og endda d\u00f8den. Her p\u00e5 Jordens overflade er vi beskyttet mod denne str\u00e5ling af vores planets magnetfelt. Det fungerer som et skjold og beskytter os.
