Radioprotection of mice with interleukin-1: relationship to the number of erythroid and granulocyte-macrophage colony-forming cells.

abstract：:Accurate assessment of risks of long-term space missions is critical for human space exploration. It is essential to have a detailed understanding of the biological effects on humans living and working in deep space. Ionizing radiation from galactic cosmic rays (GCR) is a major health risk factor for astronauts on ext...
