(Askeri) VAN ALLEN RADYASYON KUŞAKLARI: Dünya manyetik sahasına hapsedilmiş yüksek enerji yüklü partiküllerin bulunduğu sahalara verilen genel isim. Bu kuşakların büyüklüğünü ve şeklini tarifi bir radyasyon yoğunluk ölçüsü ve hakim partikül unsurlarının seçilmesine bağlıdır. Bulundukları bilinen kuşaklar şunlardır: 1. ortalama 200 mil irtifa jeomanyetik ekvatorda toplanmış proton sahası; 2. ortalama 1200 mil irtifada jeomanyetik ekvatorda toplanmış bir elektron sahası. 3. ortalama 20.000 mil irtifada jeomanyetik ekvatorda toplanmış ve birbiri üzerine binmiş elektron ve proton sahaları. Ayrıca suni kaynaklardan hapsedilmiş radyasyon sahaları da mevcuttur. gezegenler arası keşifte bir engel meydana getiren bu kuşakların mevcudiyeti ilk defa, Iowa devlet üniversitesinden Dr. James A. Allen tarafından haber verilmiştir

Definition of van allen radiation belt in English English dictionary

Any of similar areas around another planet

Either of two torus-shaped areas of high-energy charged particles which partly surround Earth, trapped by its magnetic field. The areas are characterised by intense radiation. When the belts "overload", particles strike the upper atmosphere and fluoresce, causing the polar aurora

Van Allen radiation belts

plural form of Van Allen radiation belt

Van Allen radiation belts

Two doughnut-shaped zones of highly energetic charged particles (see electric charge) trapped at high altitudes in Earth's magnetic field. Named for James A. Van Allen (b. 1914), who discovered them in 1958, they are most intense over the Equator and effectively absent above the poles. The two zones merge gradually, with the flux of charged particles showing two regions of maximum density. The inner one, mostly protons thought to be produced by primary cosmic rays striking the atmosphere, is centred about 3,700 mi (6,000 km) above Earth's surface. The outer region includes some helium ions from the solar wind and is centred about 12,500 mi (20,000 km) above Earth's surface. Intense solar activity (see solar cycle) causes disruptions of the belts, linked in turn with such phenomena as auroras and magnetic storms

van allen belt

a belt of charged particles (resulting from cosmic rays) above the Earth trapped by the Earth's magnetic field
