High energy electrons in the radiation belts pose risk to space-based technologies and manned spaceflight. One strategy to mitigate these energetic particles is to apply low-frequency radio waves that interact with and displace the particles, leading to drop-out ('precipitation') into the atmosphere below. The method relies on successful VLF radio transmissions in the magnetized plasma surrounding the Earth. In this study we explore how the radiation resistance depends on plasma parameters gyrofrequency and plasma frequency. We found that radiation resistance trends well with the electron gyrofrequency cubed, with good overall match to a recently developed space radiation model. This work suggests that placing the spacecraft in a strong magnetic field region should produce high levels of transmitted radio power into the plasma.
