Which of the following is not an example of ionizing radiati

Click For Summary
SUMMARY

The discussion clarifies that radio waves are classified as non-ionizing radiation, while protons and alpha particles are examples of ionizing radiation. X-rays are also confirmed to be ionizing due to their high energy. The confusion arises from the interpretation of the question regarding the inclusion of protons in the types of ionizing radiation. The reference to the Wikipedia page on ionizing radiation provides additional context for understanding these classifications.

PREREQUISITES
  • Understanding of ionizing vs. non-ionizing radiation
  • Familiarity with electromagnetic spectrum
  • Knowledge of particle physics, specifically protons and alpha particles
  • Ability to interpret scientific terminology and classifications
NEXT STEPS
  • Research the properties of ionizing radiation, focusing on protons and alpha particles
  • Study the electromagnetic spectrum and the classification of radiation types
  • Learn about the effects of ionizing radiation on matter
  • Explore the applications of X-rays in medical imaging and their ionizing nature
USEFUL FOR

Students in physics, educators teaching radiation concepts, and professionals in health physics or radiation safety will benefit from this discussion.

Homework 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

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.
 
Physics news on Phys.org
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.
