Radiation Shielding To Spacecraft using 10BN Nanotube:
The risks of exposure to space radiation are the most significant factor limiting humans’ ability to participate in long-duration space missions as like Space Colony.
For Black Pearl, Advanced nanomaterials such as the newly developed, isotopically enriched boron nanotubes could pave the path to future spacecraft with nanosensor-integrated hulls that provide effective radiation shielding as well as energy storage.
Space radiation is qualitatively different from the radiation humans’ encounter on Earth. Once astronauts leave the Earth's protective magnetic field and atmosphere, they become exposed to ionizing radiation in the form of charged atomic particles traveling at close to the speed of light. Highly charged, high-energy particles known as HZE particles pose the greatest risk to humans in space, as mentioned above.
One of the shielding materials under study is boron 10. Boron 10 captures neutrons and we use it as a radiation shield in Geiger Counters as well as a shielding layer in nuclear reactors.
The specific application of isotopic 10BN nanotubes includes radiation shielding. The large-quantity production of pure boron nanotubes is a major problem for future practical applications such as radiation shielding because it requires a large quantity of this material. To solve this problem, we can use the ball milling method. By this method, boron nanotubes with different isotopic, structures, and sizes can be produced.
