Overview

• Earths protection.
• Radiation in Near Space.
• Shielding Schemes.
• Materials.
• Conclusion.

3
Earths 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.

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.
