Radiation is a stand-alone lecture and an article. It overlaps areas such as radiation astronomy, radiation chemistry, radiation biology, and radiation physics. There are aspects included in the various health sciences and medicine. It is included as part of the astronomy course on the principles of radiation astronomy.

You are free to take this quiz based on radiation at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, and in the course template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

A suggestion is to have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Research

Hypothesis:

  1. The radiation doses received by NASA and RSA astronauts probably is not causes medical symptoms of spaceflight.

Control groups

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
