GRA Country of Origin: United States Country of Publication: United States Abstract: (NTIS NTS) This report presents triangulation computations data for Eniwetok Atoll in 1948. A scheme of first-order triangulation composed of check figures was executed along the eastern side of the atoll from a first-order base line on Runit Island. This scheme extends northward to Engebi Island and southward to Aniyaanii Island, and was executed for the purpose of coordinating local surveys on the activated islands and to establish distances and azimuths between certain installations. All observations were made at night, and standard procedure was followed throughout. The maximum triangle closure for the entire scheme was 02.41 seconds and the average 01.01 seconds. The maximum triangle closure in the base expansion figure was 01.10 seconds and the average 00.55 seconds.

Subfile: BRA (Energy Research Abstracts). Sandstone report No. Washington, DC (USA) 19 GRA (NTIS NTS) Country of Origin: United States Country of Publication: United States Abstract: The flux of fast neutrons of energy greater than 3 MeV was measured by means of sulfur, and neutrons of this energy were found to be lethal (assuming 10/sup 11/ n/em/sup 2/ is lethal) at distances from 650 yards jn Test Yoke to 500 yards in Test Zebra. The slow-neutron flux as measured with arsenic in Test Zebra indicated that these would have been lethal (assuming 5 x 10/sup 11/ n/cm/sup 2/ is lethal) at about 100 yards greater distance than at the sulfur neutrons. Absorption measurements made with steel and concrete indicate that 3 I003808
