Which of the following is not an example of ionizing radiati

  1. Sep 8, 2016 #1
    1. The problem statement, all variables and given/known data
    Q1.jpg
    2. Relevant equations
    Between Radio Waves and Protons is where my confusion lies; Online I read that Radio waves are non ionizing but if that's the answer then how are protons ionizing? I mean it's no even included in the types of ionizing radiation here: https://en.wikipedia.org/wiki/Ionizing_radiation#Types

    3. The attempt at a solution
    X-rays are among the high energy electromagnetic waves so are ionizing, B is wrong.
    Alpha particles are charged and heavy so are ionizing, C is wrong.

    There are two possibilities for this poorly worded question;
    1. they mean only to ask about radiation, wether ionizing or not;
    2. they want you to consider protons as they appear in radiation ... ie. relativistic protons.
