The Radiation Sensitivity of Phycomyces: Interaction of Visible Light and Ionizing Radiation

Abstract
The general radiation sensitivity of Phycomyces towards visible light, UV and ionizing rays is emphasized. Cultures grown in visible light differ in some of their reaction towards X-rays as compared to cultures grown in darkness, e. g., the formation rate of lactic acid. Other X-ray effects (the influence on the growth rate of the sporangiophore) are independent of whether the X-radiation is performed in visible light or in darkness.
