Understand the effects of radiation on the human body

Multi-fluorescent chromosome map of a cell exposed to cosmic
radiation. The Biodosimetry in astronauts experiment will analyse tissue samples taken before and after spaceflight to help clarify the the effect that space radiation has on DNA, and the role of the space environment in modifying the radiation sensitivity of the bodily system of organs and tissues, primarily the bone marrow, spleen, tonsils, and lymph nodes, involved in the production of blood.
