US Spacesuit Knowledge Capture - Recorded June 29, 2017

The spaceflight ionizing radiation (IR) environment is dominated by very high-kinetic energy-charged particles with relatively smaller contributions from X-rays and gamma rays. The Earth’s surface IR environment is not dominated by the natural radioisotope decay processes. Dr. Steven Koontz’s lecture will provide a solid foundation in the basic engineering physics of space radiation environments, beginning with the space radiation environment on the International Space Station and moving outward through the Van Allen belts to cislunar space. The benefits and limitations of radiation shielding materials will also be summarized.
