Cosmic radiation can cause Alzheimer's in astronauts
Space travel may harm the brain in astronauts as exposure to
galactic cosmic radiation could trigger
Alzheimer's, a new study has claimed.
The race for space tourism may be hotting up, but the practicalities of intergalactic travel have hit a new obstacle as research for the first time showed that radiation exposure in space can lead to cognitive problems.
The Earth's magnetic field generally protects the planet and people in low earth orbit from these cosmic radiation, but once astronauts leave orbit they are exposed to constant shower of various radioactive particles.
Tests on mice with models of Alzheimer's showed that after they were exposed to various doses of radiation, including levels comparable to what astronauts would be experience during a mission to Mars.
