WebOrbital inclination - the closer a spacecraft's orbit takes it to the Earth's poles (where Earth's magnetic field concentrates ionizing particles), the higher the radiation levels will be. Altitude above the Earth - at higher altitudes the Earth's magnetic field is weaker, so there is less protection against ionizing particles, and spacecraft ... WebNear the equator, where the Earth's magnetic field is more nearly horizontal, the E1 field strength is more nearly symmetrical around the burst location. [citation needed] At geomagnetic field strengths typical of the mid-latitudes, these initial electrons spiral around the magnetic field lines with a typical radius of about 85 metres (280 ft).
