MEASUREMENT OF MATERIAL DENSITY WITH BETA DENSITOMETER

Abstract

The objective of beta-densitometer instrumentation at Ivy Mike shot was, primarily, to measure material density near ground surface as a function of time and, secondarily, to test the latest modifications to previous densitometer models. The results showed (1) that thermal or preshock dust is absent at a ground range of about 23,000 ft (Station 690.02), (2) that it is possible to calculate the overpressure due to air shock alone from the measured density change, provided that preshock turbulence is not excessive, and (3) that the modifications to the densitometer proved to be satisfactory. The calibration and electronic engineering of the Ivy model densitometer were considerably improved over previous models.
