The International Space Station provides greater radiation shielding than interplanetary spacecraft due to Earth's magnetosphere
The International Space Station benefits from partial shielding provided by Earth's magnetic field, resulting in a more favorable radiation environment compared to unprotected interplanetary space.
Papers [10] and [11] explicitly contrast the radiation environment in low-Earth orbit (LEO), where the ISS resides and benefits from Earth's magnetosphere, with interplanetary or deep space missions where that protection is absent.

This paper reviews space radiation dosimetry in low-Earth orbit (such as the ISS) and interplanetary space, highlighting how Earth's magnetosphere and trapping characteristics shape the radiation environment compared to deep space.

This paper compares space radiation scenarios in low-Earth orbit versus deep space, noting that interplanetary space exposure is more severe due to the limited or absent protective effect of Earth's magnetosphere.
