WebMar 10, 2024 · The Van Allen belts put artificial satellites at risk, so they must have their sensitive components properly protected with adequate shielding when they spend a certain time in this zone [3 ... WebDec 10, 2024 · The Van Allen radiation belts are made of trapped “particle radiation”, predominantly protons and electrons. The Earth’s magnetic field, generated by the Earth’s iron core, is responsible for this trapping, binding them to gyrate around these magnetic field lines, and they bounce at low altitude when the magnetic field becomes stronger. ... WebMay 1, 2024 · These particles gyrate, bounce, and drift through two concentric, donut-shaped rings called the Van Allen belts, sometimes shooting down to Earth’s atmosphere or escaping into space. Named for James Van Allen, their discoverer, these radiation belts are located in the inner region of Earth’s magnetic environment, the magnetosphere. daily catch seafood pearl river la
