Measurements were made of the velocity and distance of translation of anthropomorphic dummies and equivalent spheres caused by blast winds. The primary technique for recording the movement of these ohjects was phototriangulation. The secondary technique (applicable to certain of the equivalent spheres) was to have the spheres impelled into missile traps. The resultant penetration provides a means for determining the velocity at the time of impact. Analysis of the results from both the primary and secondary techniques is expected to provide some of the irformation identified in the objective. (auth)

Attempts are reported to obtain records of transient air temperatures at selected locations in a blast biology underground shelter during nuclear explosions. No records were obtained due to failure of equipment. An evaluation of thermal burns was made on Chester White pigs used as test animals. One pig in the entrance and one about three feet inside the door received severe burns, while animals away from the entrance and those in the slow fill side received no burns. Possible explanations are discussed. (C.H.)

The results of temaperature measuring experiments conducted for Rainier shot, Operation Plumbbob are described, The temperature distribution in the surrounding tuff resulting from the detonation of an underground nuclear device yielding 1.7 kilotons of energy has been measured, Data indicate peak temperatures in the vicinity or 90 deg existing in the central regions which drop rapidly to approach ambient temperatures at distances of about l80 feet from the original ground zero, Based on measurements taken in three holes drilled into the central regions, contours of constant temperature are constructed The temperature picture is consistent with the consideration that most of the heat entered the water contained originally in the tuff and the unconsolidated material which filled the cavity after its initial collapse, The amount of energy contained in the central regions in the form of tuff heated to below 90 deg C is roughly estimated to be greater than one-half of the total energy release. An unsuccessful attempt to measure the temperature rise across the shock front of the pressure wave produced by the detonation is described, and reasons for failure are discussed.

A gamma-radiation telemetering system was utilized to measure fall-out levels at the Ncvada Test Site. Two methods of signal transmission were used: directcoupled field lines for on-site installations and commercial telephone lines for areas out to 330 miles. Graphic and tabular data cover on-site and off- site residual gamma-radiation dose rate measurements taken as a function of time after selected events. (auth)

From abstract: A gamma-radiation telemetering system was utilized by Civil Effects Test Group personnel to measure fallout levels at the Nevada Test Site from the vicinity of Ground Zero out to, and including, an area bounded by Reno, Nevada; Salt Lake City, Utah; Kingman, Arizona; and Barstow, California.

"The objective of project 32.3 was to evaluate some operational characteristics of a radiological shelter and to determine values for some countermeasures-system parameters."
