ABSTRACT The loading problem is to predict the forces imposed on an isolated structure which is gtruck by a given blast wave moving across the structure in a direction normal to one of its faces, and the net horizontal and vertical forces as function of time are found for the period during which the structure is 801. immersed in the wave. The development of the loading method was accomplished by a study of known theory and existing experimental data. Data obtained by shock tube studies were combined with theory to produce a set of fundamental parameter plots and a rational load-computation method. Equations of motion, used in the prediction of response, are discussed and possible alternate methods of solutions are given. Subjects for future investigations are discussed.

ABSTRACT The production by ionizing radiations of color centers in alkali halide crystals and fluorescent centers in Ag-bearing phosphate glasses was investigated as a basis for casualty-badge radiation dosimeters. Doses of 25 r of {sup 60}Co {gamma} rays were detected by visible color changes in KBr and KCl crystals sensitized by heating in a combined atmosphere of alkali vapor and hydrogen. The sensitivity of the phosphate glass is comparable to that of the crystals, but a reading device is needed for the fluorescent measurements. The crystals and glasses are strongly energy~ dependent for x-ray energies below “about 150-kV effective. The crystals and glasses can be bleached by strong illumination in their respective optical absorption bands; consequently, the exposed dosimeter elements must be shielded from light between observations. In a test bomb detonation the crystals and glasses were exposed to total dosages of 17 to 4460 r at 5003478 OFFICIAL USE ONLY
