FALL-OUT AND CLOUD-PARTICLE STUDIES

The major objectives of Project 5.4b were to conduct the following studies in connection with the surface detonation of a thermonuclear device and an airdrop high-yield fission bomb: (1) To determine the fall-out pattern with its characteristics of activity, particle size, and radiochemical content...

Description
Summary:The major objectives of Project 5.4b were to conduct the following studies in connection with the surface detonation of a thermonuclear device and an airdrop high-yield fission bomb: (1) To determine the fall-out pattern with its characteristics of activity, particle size, and radiochemical content on the land areas at Eniwetok Atoll; and (2) To determine the rate of fall-out at various locations on Eniwetok Atoll during the first 6 1/4 hr after each shot. The objectives were accomplished by (1) sampling the fall-out with intermittent- fall-out collectors, trays, wash tubs, and Tracerlab air monitors and by (2) analyzing the particulate matter for activity, decay, particle size, and radiochemical content.
