Abstract
A radon decay product remover for use in a conventional, residential lamp. The remover screws into the light bulb socket of a lamp and provides a replacement socket for a light bulb. The flow of electric current to the light bulb is controlled by an on-off switch in the radon decay product remover. When used in a table lamp, an ion generator includes electrodes (from which negative and/or positive ions are emitted) that attach to the exterior of the lamp shade.
