The Radi-N2 experiment aims to characterize neutron radiation in various locations of the International Space Station (ISS). As part of this experiment, bubble detectors produced by Bubble Technology Industries were deployed in the JPM1D5 area of the ISS. The dose information gathered from these detectors will be used to assess the neutron radiation exposure of astronauts onboard the ISS.
