A system and method for reducing energetic proton flux trapped in the inner radiation belt by injecting Ultra Low Frequency (ULF) electromagnetic waves is disclosed. The ULF electromagnetic waves is generated by space or ground based transmitters and the frequency range is selected such that the injected waves are in gyrofrequency resonance with trapped 10 to 100 Mev protons.
