\u00dcks suurimaid ohte astronautide tervisele on kosmosekiirgus. Valguse kiirusele l\u00e4hedase kiirusega kosmoses liikuvad k\u00f5rge energiaga osakesed v\u00f5ivad p\u00f5hjustada keharakkudele suuri kahjustusi, mis suurendab m\u00e4rkimisv\u00e4\u00e4rselt v\u00e4hiriski. Et selgitada v\u00e4lja, kuidas meeskonnaliikmeid selle kiirguse eest k\u00f5ige paremini kaitsta, teeb ESA koost\u00f6\u00f6d \u00fche Saksamaa keskusega, et testida erinevaid kiirguskaitseviise, sealhulgas Kuu ja Marsi pinnast.<\/p>\n<\/div>\n

Kosmos on t\u00e4is laetud osakesi, mis t\u00e4hendab, et astronaudid on ametlikult liigitatud kiirgust\u00f6\u00f6tajateks. M\u00f5ned osakesed p\u00e4rinevad P\u00e4ikesel toimuvatest intensiivsetest, kuid l\u00fchiajalistest tormidest. Teised, mida nimetatakse kosmilisteks kiirteks, tekivad kaugetes galaktikates surevate t\u00e4htede tegevuse tulemusel.<\/p>\n

Praegu ei ole kosmosekiirgus eriti suur probleem, sest Rahvusvaheline Kosmosejaam tiirleb Maa magnetv\u00e4lja piires. See magnetv\u00e4li toimib kilbina enamiku kosmosekiirguse vastu. Kuid Kuule ja Marsile suunduvate meeskondade jaoks kujutab k\u00f5rge energiaga kosmiline kiirgus palju suuremat ohtu, mist\u00f5ttu on vaja spetsiaalset kaitset.<\/p>\n

ESA meeskond kasutab Saksamaal Darmstadtis asuvat GSI osakeste kiirendit potentsiaalsete kaitsekilpide materjalide testimiseks. Testitavate materjalide hulka kuuluvad alumiinium, vesi, pol\u00fcet\u00fcleenplast, mitmekihilised struktuurid ning Kuu ja Marsi materjalide simulatsioonid.<\/p>\n

Tihedam ja paksem kiirguskaitse ei ole alati parem. Metallkaitsekihtidele p\u00f5rkuvad kosmilised kiired v\u00f5ivad tekitada sekundaarosakeste vihmu, mis v\u00f5ib olla isegi veel kahjulikum. \u00dcldiselt pakuvad kergemad materjalid, nagu vesi ja plast, paremat kaitset. \u00dchendkuningriigi \u00fche ettev\u00f5tte poolt v\u00e4lja t\u00f6\u00f6tatud uued, vesinikurikkad materjalid tunduvad seni v\u00e4ga paljulubavad.<\/p>","protected":false},"excerpt":{"rendered":"
