that the radioactivity was decaying at a relatively low rate, which became slower with samples collected late in the survey. These observations indicate that the longer-lived isotopes were being taken up by the algae.

Journal Announcement: NSA14 Document Type: Book Analytic Language: English The nature and extent of skin damage which may result from exposure to large amounts of high-level radioactive fall-out are discussed. Data are reviewed on the clinical findings on the Marshallese accidentally exposed to prompt fall-out from a high yield thermonuclear device in 1954. estimated that these individuals received approximately 175 r of ™ It was penetrating gamma radiation in addition to large doses of beta radiation to the skin. It was not possible to calculate the dose to the skin from beta radiation with any reasonable degree of accuracy. Estimates indicate that the surface of the skin probably received in the order of 5,000 or more rads. Symptoms are described which developed following exposure. The relative importance of beta and gamma radiation in fall-out materials in terms of casualty production is discussed. (C.H.)
