Nuclear -- Radiation effects (IMAGE) DOE/Oak Ridge National Laboratory Caption Researchers are using organ-on-a-chip technology to design a microenvironment of human microvascular cells to test how radiation could affect human respiration. These non-irradiated cells have successfully grown and stretched to cover the upper and lower surfaces of the researchers' new design.
