CO OZNACZA SŁOWO RADIATION BELT
Pasek promieniowania Van Allen
Pasek promieniowania Van Allen jest jedną z co najmniej dwóch warstw energetycznych naładowanych cząstek, utrzymywanych na miejscu wokół Ziemi przez pole magnetyczne planety. Pasy rozciągają się od wysokości około 1000 do 60 000 kilometrów nad powierzchnią, w której poziomy promieniowania regionu różnią się. Większość cząstek tworzących taśmy uważa się za pochodzące z wiatru słonecznego i innych cząstek promieni kosmicznych. Pasy są nazwane od swojego odkrywcy, Jamesa Van Allaha i znajdują się w wewnętrznym obszarze magnetosfery Ziemi. Pasy zawierają energiczne elektrony, które tworzą zewnętrzny pas i kombinację protonów i elektronów tworzących pas wewnętrzny. Pasy promieniowania zawierają dodatkowo mniejsze ilości innych jąder, takich jak cząstki alfa. Pasy powodują zagrożenie dla satelitów, które muszą chronić elementy wrażliwe przed korozją, jeśli ich orbita spędza znaczny czas w pasach promieniowania. W roku 2013 NASA poinformował, że sondy Van Allen odkryły przejściowy, trzeci pas promieniowania, który obserwowano przez cztery tygodnie, aż do zniszczenia potężnej, międzyplanetarnej fali uderzeniowej Słońca.
Definicja słowa radiation belt w słowniku
Definicja pasma promieniowania w słowniku to obszar w magnetosferze planety, w której naładowane cząstki są uwięzione przez pole magnetyczne planety, przykładem są ziemskie pasy Van Allena.
