  • Patent number: 5066597
    Abstract: An apparatus is disclosed for housing radioactively and biologically contaminated waste materials during treatment thereof to inactivate the biological contaminants and render the wastes more suitable for disposal in a solid landfill. The apparatus is nonporous and thermally resistant. Additionally, the apparatus features at least one opening within which is disposed a filter for entrapping any radioactive compounds contained in gases exiting the apparatus during the treatment. The apparatus is used in conjunction with an autoclaving procedure which inactivates the biological contaminants while preventing volatile radioactive compounds from escaping into the environment.
    Type: Grant
    Filed: April 10, 1989
    Date of Patent: November 19, 1991
    Assignee: Massachusetts Institute of Technology
    Inventors: Margaret C. Stinson, Mitchell S. Galanek
  • Patent number: 5047348
    Abstract: An apparatus for housing radiation-emitting items to be incubated, such as radio-labeled cell cultures, in order to prevent contamination of the interior of an incubator and the surrounding environment. The apparatus is nonporous and preferably relatively thermally resistant. Additionally, the apparatus features a selectively sealable lid and has at least one opening within which is disposed a filter for entrapping any radioactive compounds contained in gases exiting the apparatus during incubation. The apparatus is used in conjunction with known incubation procedures of radiolabelled cell cultures or other items.
