Abstract
IT is well known that the sensitivity of cells to ionizing radiation is commonly increased two- to three-fold by the presence of oxygen in their immediate surroundings. A great variety of plant and animal cells show this effect, but it has apparently not been demonstrated in chlorophyll-containing cells. This report describes such a demonstration and also presents evidence that oxygen generated intracellularly in photosynthesis leads to the same sensitization as oxygen from extra-cellular sources.
