What long-term cognitive deterioration is suggested as a consequence of low doses of Galactic Cosmic Radiation (GCR)?
Answer
Deterioration of executive functions, impacting learning and memory
While high doses of radiation carry the acute risk of immediate sickness, exposure to lower, chronic levels of Galactic Cosmic Radiation (GCR) presents severe long-term neurological consequences. Studies indicate that this continuous mixed-field exposure can interfere directly with cognitive processes. Specifically, low doses of GCR are linked to impacts on learning capabilities and memory retention. Over extended periods, this subtle interference can lead to a measurable decline in executive functions—the high-level cognitive skills necessary for planning, decision-making, and complex problem-solving, which are vital for astronaut performance during lengthy missions.
