NEWNET's Radiation Quiz

Here is a simple quiz on some basic facts about radiation. Check the desired answer, and press any of the "go" buttons. You may answer all of the questions at once, or you may answer one (or a few) at a time and just see the results for the questions you have answered.

  1. Background radiation levels:
    are constant world-wide, except during times of solar flares.
    decrease with elevation.
    depend on altitude and type of rock or soil in the area.



  2. There are a number of types of nuclear radiation, such as alpha, beta, and gamma rays. Gamma radiation is:
    High energy electrons.
    High energy neutrons.
    High energy protons.
    High energy helium nuclei.
    High energy electromagnetic radiation, similar to light and x-rays.



  3. Compared to alpha and beta radiation, gamma radiation penetrates matter:
    the most.
    the least.
    about the same as other types of radiation.



  4. According to the U.S. Department of Energy, if an area produces a background radiation dose rate of 10 microrem per hour (87.6 millirem per year), then the allowable radiation dose to the public from DOE facilities would be:
    12.4 millirem per year.
    100 millirem per year.
    5 rem per year.
