  • The uptake and retention of cesium-134 in Microtus canicaudus Miller

    Creator:
    Lei, Wayne
    Abstract:
    A study was performed to assess the uptake and retention patterns of cesium-134 in the gray-tailed vole, Microtus canicaudus Miller. To furnish a realistic source of contaminated food for the voles, wheat seedlings were raised in hydroponic solutions to provide radiocesium labeled wheat clippings. The hydroponic system was designed to...

  • Effects of fractionated radiation doses on survival times of the newt (Taricha granulosa)

    Creator:
    Campbell, Carol Lee
    Abstract:
    This was a study designed to determine the occurrence of recovery from radiation damage in Taricha granulosa. Irradiation with either gamma or x-ray sources in the range of 96-10,000 rads was given. (The mean or median survival times were determined.) Doses were fractionated and the survival times for the same...

  • The site of action of radio-lethal compounds on Micrococcus radiodurans

    Creator:
    Manes, Jasper Damon, Jr.
    Abstract:
    Iodoacetic acid and diphenylamine were used in this study to elucidate the mechanisms of resistance of Micrococcus radiodurans to radiation. This organism, a gram positive, non-spore forming, salmon-pink, tetracoccus has a LD₅₀ of 213,000 R when grown in the absence of radio-modifying agents. M. radiodurans, when grown in media containing...
