The full text of this report is available for sale.

Pressure-time measurements were made of the underwater pressure waves generated in Tests Able and Baker. No records permitting analysis were obtained in Test Able because the explosion occurred some distance from the intended targets and pressures at the gage location were far below those for which the instrument had been set. In Test Baker three pressure-time records were obtained. Because of poor response characteristics of the recording channels, the records ...

OPERATION CROSSROADS. RESIDUAL EFFECTS OF ATOMIC RADIATION IN SOILS ON SEED GERMINATION

29 JAN 1947

14 pages

Authors: Roger P. Humbert; Edwin F. Miles; Eben H. Toole; Vivian K. Toole; JOINT TASK FORCE ONE WASHINGTON DC

Geneticists are convinced that exposure to X-rays and similar radiations greatly speed up the appearance of mutations. It was desirable to define the residual effects of atomic radiation on soil. Thirty-six samples of three soils, namely Caribou loam form Maine, Decatur clay loam from Georgia, and Houston clay from Texas were sent to Joint Task Force ONE and were placed on ships at varying distances from the target. After exposure ...

1947

103 pages

Authors: Irwin Vigness; JOINT TASK FORCE ONE WASHINGTON DC

A considerable amount of Navy gear mounted aboard ship is held in position by flexible supports. These equipments have several modes of vibrations whose frequencies are easily determinable. The maximum displacements of these equipments with respect to their supports are of interest from the viewpoint of the suitability of the mounts in protecting the equipments from damage and also from the viewpoint of determining the relative intensities of shock at ...

OPERATION CROSSROADS. WELDING

1947

118 pages

Authors: G. B. Grable; JOINT TASK FORCE ONE WASHINGTON DC

In general, the overall performance of welded construction in target vessels subjected to the atomic bomb explosions at Bikini was very satisfactory. There were, however, enough weld failures to warrant certain conclusions as to which types of defects are to be more commonly expected in naval construction and the influence these defects have on the performance of structures and assemblies under blast and shock loading. Welding materials and equipment appear ...
