Agnirva Space Premier League - Expedition #31646: Shielding Space Travelers: The NEUtron DOSimetry & Exploration Project by McMaster University

Radiation is one of the greatest challenges in space exploration, and McMaster University’s NEUtron DOSimetry & Exploration (NEURODE) experiment took a giant leap in tackling that issue. This ISS-based project focused on measuring neutron radiation, a type of ionizing radiation that’s particularly dangerous to astronauts.

Traditional dosimeters used in space primarily focus on charged particles. However, neutrons, being uncharged, require specialized detection techniques. The NEURODE team, led by Drs. Andrei Hanu, Eric Johnston, and Soo Hyun Byun, designed advanced neutron sensors to better understand how these particles behave in microgravity.

During Expedition 68, the instruments were installed on the ISS to collect detailed data on neutron flux and energy distribution. The sensors used solid-state technologies that could differentiate between neutron energies and map radiation exposure more accurately than ever before.

Understanding neutron behavior is vital for designing better radiation shielding for spacecraft and habitats. The findings from NEURODE will be crucial for long-term missions to the Moon and Mars, where radiation exposure will be a constant threat.

This project exemplifies cutting-edge research with real-world applications and demonstrates how universities can lead technological innovations for the future of human spaceflight.
