OPERATION SUNBEAM, SHOT SMALL BOY. Project Officers Report - Project 6. 4. Measurement of Gamma Dose Rate as a Function of Time

Abstract

The primary objective of this project was to obtain measurements of gamma rate as a function of distance and time for evaluation of the electromagnetic (EM) effect. The secondary objective was to measure the gamma rate as a function of distance without involving the EM effect. Such data are of interest in connection with transient radiation effects on electronic components. A newly developed gamma detector, called SEMIRAD, was used. The reason for choosing this device rather than other conventional gamma detectors is its extremely rapid time response, limited only the collection time of the secondary electrons, and its high dose-rate saturation limit. Results of the gamma-dose-rate measurement as a function of time are fragmentary and represent an undistorted measurement in only a few intervals. Failures of equipment and/or human factors accounted for missing data. The data could be improved in future experiments if changes are made in the instrumentation, i.e., better EM shielding, improved tape recorders and generally higher quality electronics.
