ocr: Van ALLEN RADIATION BELTS Van Allen belts. Layers of magnetic field around the Earth. These belts capture the electronically charged particles which are brought to Earth by solar wind. They are composed of the inner and outer belts. The inner belt, which contains high-energy protons, is located around the equator, all the way to the 30° latitude at the altitude of about 1,000 - 10,000 km. The outer belt, which contains high-energy electrons, lies at the altitude of about 20,000 - 30,000 km and reaching to the 60° latitude. The intense radiation in Van Allen radia- tion belts is hazardous both ...
