Researching the Effects of the Presence and Absence of Ionizing Radiation (REPAIR): a Deep-Underground Biology Experiment

In order to understand the biological effects of Earth’s Natural Background Radiation (NBR), we must go deep-underground. In a controlled subterranean laboratory, shielded from Galactic Cosmic Radiation (GCR), the REPAIR Project investigates the role of this NBR and GCR in a variety of model systems. This includes mammalian cells, yeast, nematode worms, fruit flies, and the embryonic development of fish. REPAIR helps us understand the role NBR has played in the evolution of DNA repair mechanisms and biological responses to ionizing radiation exposure.
