What is the Best Radiation Shielding for the Surface of Mars? universetoday storybywill
“We built a computational model of Mars and measured the cosmic energy deposition inside a hypothetical human phantom, representing an astronaut,” he said. “A shield of material was set to absorb some part of the radiation before reaching the astronaut. The most effective materials, in terms of radiation protection, were the ones which let the least energy passing in the astronaut’s body.”
“For example, although aluminum was not found to be as effective as other materials, it can still be helpful in reducing radiation doses, and we advocate combining it with other materials. Martian regolith has similar behavior and the advantage of being an in-situ material, not requiring us to carry it from Earth.”
