  • Radiochromic imaging method
    Patent number: 6621086
    Abstract: The present invention relates to radiochromic imaging methods for generating a permanent colored spatial representation of an irradiation pattern wherein the intensity of the color in the image correlates to the dose level of irradiation, and more particularly to a method that provides representations of the quantity and position of radiolabelled polymeric materials separated by chromatographic techniques and furthermore, to a method that provides a two or three dimensional colored image correlating to a dosimetric pattern supplied by an external or embedded source.

  • Use of glass fiber materials in diagnosing and preventing radon infiltration into buildings
    Patent number: 6036753
    Abstract: A method and apparatus for testing and remediating the effects of radon infiltration in buildings. The method of this invention places fiber glass materials over radon-emitting surfaces in order to entrap radon and radon progeny. The fiber glass materials can be formed into mats having a packed geometry. Each mat has fiber bundles having several thousand individual fibers. Each fiber has an approximate diameter size of about 50 microns. The glass fiber consists of a silicon oxide glass that may be doped, for example, with trivalent cerium ions. The mats can be of any geometrical configuration, such as rectangular.
