  1. The Effects of Electromagnetic Radiation and Shielding on Health in Near Space Environments Philip Sugimoto Engr 302 5/9/01

  2. Overview • Earth’s protection. • Radiation in “Near Space”. • Shielding Schemes. • Materials. • Conclusion.

  3. Earth’s Protection • Van Allen Radiation Belts. • Ionosphere acts as a shield. • Equivalent of 10 tons/meter squared.

  4. Radiation in “Near Space” • Electromagnetic (x-ray and gamma ray). • Energized Particles (proton and electron). • Hot Matter. • Cosmic Radiation.

  5. Shielding Schemes • Active Shielding. • Passive Shielding. • Rotating Station, Rotating Mass. • Rotating Station, Stationary Mass. • Stationary Station, Stationary Mass. • Lunar Shielding.

  6. Active Shielding

  7. Materials and Construction • Electrical interference. • Surface Degradation. • New Materials.

  8. Conclusion • Human Health and Long-Term Residence in “Near Space”. • Expensive but possible. • Societal, Political and Economics. • Will eventually occur due to push from one of these areas and the others will follow.
