ISS Science for Everyone

Science Objectives for Everyone
BTN-Neutron-Radiation-ISS is an external facility that measures the exposure of ISS to neutron and gamma radiation that come from solar flares. This device helps researchers to improve current on-orbit radiation models and examine the complete radiation dose the astronauts and cosmonauts receive during EVAs.
Science Results for Everyone
Superman battled Neutron; astronauts battle neutrons. To improve calculations of how much radiation crew members are exposed to during extravehicular activity, researchers took measurements outside the space station. Their findings indicate that radiation amounts vary significantly depending on the station’s orbital position. Taking into account differing levels of solar activity, new data confirm the increase of cosmic radiation and harmful neutron during periods of low solar activity.
