REPAIR studies the effect of very low background radiation levels on living organisms. It looks for cancer risk and DNA changes in human cells, and whole-organism development and growth in lake whitefish embryos.

Did you know?

  • REPAIR is one of the deepest biological life sciences research projects in the world.
  • REPAIR is testing the hypothesis that because all life on Earth evolved in the presence of natural background radiation, the absence of it could be detrimental to biological systems.
  • Lake Whitefish were chosen because they remain as embryos for 100-200 days (a long time for fish). This allowed scientists to monitor very subtle changes as they developed.
