Upon completing this Spacecraft Radiation Protection course, learners will be able to meet these objectives:
- What the models are for space environments, where to find them, and how to use them?
- What do the common radiation units mean?
- How to equate damage from different species of radiation.
- How to conduct total dose test.
- How to conduct SEE tests.
- How to use dose-depth curves in determining shield thickness.
- How to shield neutrons.
- We can adapt this Spacecraft Radiation Protection course to your group’s background and work requirements at little to no added cost.
- If you are familiar with some aspects of this Spacecraft Radiation Protection course, we can omit or shorten their discussion.
- We can adjust the emphasis placed on the various topics or build the Spacecraft Radiation Protection course around the mix of technologies of interest to you (including technologies other than those included in this outline).
- If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the Spacecraft Radiation Protection course in a manner understandable to lay audiences.
