Radiation history is the history of radiation astronomy lecture and article for the course on the principles of radiation astronomy.

This is a quiz based on the lecture that you are free to take at any time.

Once you’ve read and studied the lecture itself, the links contained within the article/lecture, listed under See also, External links and in the {{principles of radiation astronomy}} template, you should have adequate background to take the quiz.

Suggestion: Have the lecture available in a separate window.

Enjoy learning by doing!
