A method and device of shielding an area from radiation are provided. A radiation shield device may include first and second shells at least partially surrounding the area with the second shell being spaced apart from and further away from the area than the first shell. Both the first and second shells include a plurality of coils that are arranged in paired coil groupings and that encircle the area to be shielded from radiation. The coil groupings of the first shell may be configured to support current flow in an opposite direction to that in which the paired coil groupings of the second shell are configured to support current flow. As such, each coil grouping of the first shell has north and south poles that are correspondingly oppositely positioned from the north and south poles of the paired coil grouping of the second shell.
