  • Patent number: 11977194
    Abstract: An electrostatic concentrator for use in radon detection, comprising of a plastic sheet having conductive electrodes patterned onto the surface. The sheet is patterned and cut in such a way that it can be assembled into a three-dimensional shape (e.g. a cone), such that when a voltage is applied to the electrodes an electrostatic field is created for propelling radon progeny towards a sensor on which it can be detected.
