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.
