Biological Effects

  • Biological Effects of Ionizing Radiation

Commercial Use of Radioactive Materials

  • Radioactive Dentures
    Millions of people wear some type of dentures (false teeth). Some of them, especially the oldest ones, are made out of porcelain that includes a trace of uranium, a radioactive element.
  • Irradiated Gemstones
    It is not uncommon for gemstones to be exposed to radiation in order to change their color and to increase their market value. Color changes by irradiating stones is legal, but they must be stored for a set time prior to release to let radioactivity decrease.
  • Uses of Radioisotopes
    Some of the major uses of radioisotopes in the United States.
  • Uses of Uranium in Dinnerware
    This article examines the commercial use of uranium to achieve the unique red color of a popular dinnerware line.

Farming and Radioactive Risks

  • Radiological Information for Farmers and Growers
    Disaster guide published by the Washington State Department of Agriculture designed to provide information for farmers and growers on the probable and potential effects of radiation on farming operations.

Flying and Radiation Risks

  • Radiation Risks for People Who Fly by Dr. Robert J. Barish
    Radiation exposure while flying is an issue most of us never think about. In 1992 the FAA acknowledged that pilots and flight attendants may receive more radiation annually than the average radiation worker - perhaps twice as much. Airlines were directed to educate their crew members about their radiation risk. This is the first book to address this issue.

Hormesis

  • Tales of Two Similar Hypotheses: The Rise and Fall of Chemical and Radiation Hormesis
    This paper compares the historical developments of chemical and radiation hormesis from their respective inceptions in the late 1880's for chemical hormesis and early 1900's for radiation hormesis to the mid 1930's to 1940 during which both hypotheses rose to some prominence but then became marginalized within the scientific community.

Lasers

  • How Lasers Work by Davin Flateau
    Article on the Laser Fantasy International web site explaining how laser light is produced, why it's so useful, and some of its most common applications.
  • A New Precision Cutting Tool: The Femtosecond Laser
    A Livermore team has won an R&D 100 Award for applying chirped-pulse amplification in a high-average-power mode for cutting and machining materials. The system was developed for disassembling nuclear weapons components, but it has many other uses as well.
  • Cool Facts About Lasers
