    Abstract: An alpha detector for application in areas of high velocity gas flows, such as smokestacks and air vents. A plurality of spaced apart signal collectors are placed inside an enclosure, which would include smokestacks and air vents, in sufficient numbers to substantially span said enclosure so that gas ions generated within the gas flow are electrostatically captured by the signal collector means. Electrometer means and a voltage source are connected to the signal collectors to generate an electrical field between adjacent signal collectors, and to indicate a current produced through collection of the gas ions by the signal collectors.

    Abstract: A small enclosed ion chamber with an electrostatically charged electret attached to the inner chamber wall. Filtered holes in the chamber permits radon in the ambient air in the chamber to enter or exit by diffusion. Positive or negative ions (depending on the polarity of the electret charge) formed in the chamber air by the passing of gamma radiation or X-rays move to and collect on the electret surface by virtue of its electrostatic attraction to ions of opposite polarity. These ions neutralize the ions of opposite polarity on the electret and cause a measurable reduction in its surface voltage which reduction is proportional to the dose of gamma and/or X-ray incidence on the chamber. The reduction of the electret surface voltage is used to calculate the dose of gamma or X-ray radiation incident upon the chamber during a known exposure period. In one embodiment, a sealed radioactive-gas-tight flexible-wall container, such as a bag, surrounds the chamber to prevent any ambient radon from entering the ion chamber. In addition, an absorbent such as activated charcoal can be included in the bag to remove any radon captured within the sealed chamber. Removal of this radon removes its undesirable contribution to the gamma/X-ray dose signal and thereby enhances the accuracy of the monitor.
