discussed. It was concluded that in no situation in nuclear warfare would it be possible to inhale enough fallout material to injure the respiratory or gastrointestinal tracts. On physical grounds, the acute hazards offered gamma emanation to skin and to the organism as a whole are BETA and by at least 1000 times greater than the inhalation hazards. On physioiogical grounds (the defense mechanisms of the respiratory tract) there ijs an additional protective factor of 10; the particles of the early fallout are too large to reach the pulmonary alveoli. The probability of internal contamination by the respiratory route appears to be remote, and can be ignored in the early period after attack.

Lectures in Aerospace Medicine, Sondhaus, C.A. Jan. 8-12, 1962 Publication Date: nd 211-40 p. Journal Announcement: NSA17 Document Type: Book Analytic Language: English Discussion is given on the spatial distribution of radiation as well as its nature and energy throughout the body tissues during space flight, in particular, the geometrical aspect of tissue dose and non-uniform pattern of dose deposition, and its effect on response. A brief summary is given of conclusions derived from the accidental exposure of human being to fallout radiation on March 1, 1954, in the Marshall Islands. (P.C.H.)

J.P. . Journal Announcement: NSA17 Document Type: Journal Article Language: English ~ Travel times from the 1958 series of nuclear expolsions near Bikini and Eniwetok islands to Australian seismic stations are studied. at distances between 25 deg and 63 deg For stations the mean residuai for P from the 9003623 Australian National Univ., Canberra Journal of Geophysical Research (U.S.) v 68. Publication Date: Feb. 15, 1963 1115-20 p. Coden: JGREA Note: 0022-1406 Jeffreys-Bullen times for a surface focus is -1.6 plus or minus 0.7 sec, agreeing with traveltime determinations to other continents. Times to Rabaul (19 deg and 21 deg ) strongly suggest a sharp bend in the P curve near 17 , corresponding to the ‘‘20 deg discontinuity.’’ There is aiso a possible bend near 25 deg to 26, but this wouid be less marked. Data are given.
