Since strain B is more sensitive to x-rays, the rate of killing is greater under both conditions studied; nevertheless the ratio of sensi- tivity of oxygen-treated cells to nitrogen-treated cells is approximately equal to that found for B/r. Nitrogen can be replaced with helium, hydrogen, or carbon dioxide without significantly changing Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Symposium on Radiobiology (1950 : Oberlin College); Nickson, James J.
