A Preliminary Study on Radiation Shielding Using Martian Magnetic Anomalies
Open accessAbstract
We propose radiation shielding using Martian magnetic anomalies to protect human crews on the Martian surface. We have simulated the trajectories of energetic protons using the Buneman-Boris method to measure how magnetic anomalies affect the impact rate on the Martian surface. Protons from the west can be completely eliminated, while those from the east are concentrated on the area between the magnetic poles. This would mean crews would need to concern themselves about radiation from the vertex and east only. A Martian magnetic anomaly can therefore be used to realize continuous and efficient radiation shielding.

With the configuration of an idealized magnetic anomaly, protons below about 1 GeV can be efficiently shielded when they enter from one side, but unaffected when they arrive from the opposite side.

The Discussion reports complete shielding of protons arriving from the west over 1 MeV–1 GeV. But it says protons arriving from the east are concentrated between the magnetic poles and radiation exposure there is significantly increased, not unaffected. (LLM, conf=0.90)
Experimental — accuracy not yet measuredEmoto et al. (2018) simulated particle trajectories entering two-dimensional magnetic fields and found that radiation shielding depends on incident particle angle, energy and geometry of the magnetic field.
“For lower-energy particles during SEP events, Emoto et al. (2018) simulated particle trajectories entering a two-dimensional magnetic fields (while ignoring their interaction with the atmosphere) and found that the radiation shielding depends on the incident particle angle, energy and the geometry of the magnetic field.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
