How does neutron radiation affect people on Earth and on the International Space Station? One of the biggest concerns for keeping humans safe in space is managing and understanding the effects of increased exposure to potentially dangerous neutron radiation. At the core of this project, students will learn how to measure the radiation they are exposed to on Earth and compare it with the radiation recorded by Canadian astronauts on the International Space Station using the same innovative technology.

One of the experiments that Canadian astronaut Chris Hadfield was responsible for during his stay on the International Space Station from December 2012 until May 2013 was RaDI-N2. This experiment measures astronauts’ exposure to potentially dangerous neutron radiation using innovative Canadian technology. CurioCity, in collaboration with the Canadian Space Agency, developed the RaDI-N2 & You Action Project to engage Canadian classrooms in a similar experiment.
