Example aspects of a deployed electromagnetic radiation deflector shield assembly and a method for using a deployed electromagnetic radiation deflector shield are disclosed. The deployed electromagnetic radiation deflector shield assembly can comprise a base station on a ground surface; a deployed electromagnetic radiation deflector shield comprising an electromagnet configured to generate a magnetic field configured to deflect radiation from a radiation source; and an upright supporting the deployed electromagnetic radiation deflector shield at a distance away from the base station, and wherein the distance is configured to prevent the magnetic field from interfering with the base station.
