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.
Claims20
An electrostatic concentrator for use in radon detection by a sensor, comprising:
- a flexible substrate in the form of a plastic film formable into a shape and having at least one opening for air to enter;
- a shape retaining mechanism for retaining the shape of the flexible substrate when formed into said shape;
- and
- a conductive pattern forming at least one electrode on the flexible substrate, such that when the flexible substrate is positioned close to the sensor and voltage is applied to the electrode an electrostatic field is created for propelling radon progeny toward the sensor.
A method of manufacturing an electrostatic concentrator for use in radon detection, comprising:
- printing at least one electrode on a flexible substrate;
- cutting said flexible substrate to form a blank;
- and
- assembling said blank to form a dome portion and a cone portion.
A method of manufacturing a blank for assembly into an electrostatic concentrator for use in radon detection, comprising:
- printing top and bottom electrodes on a flexible substrate in the form of a plastic film;
- and
- cutting said flexible substrate to form a blank having at least one opening and a plurality of tabs and slots.
