FALLOUT SIMULATION:NUCLEAR CRATERING DEVICE SIMULATION (PROJECT DIAMOND ORE)

摘要

The report discusses the development and use of the neutron activable tracer iridium to tag mineral particles in high explosive cratering charges (1) to simulate radioactive fallout from a nuclear cratering detonation and (2) to determine the effect on venting of various methods of stemming the charge emplacement hole. Data from four 907-kg (1-ton) and four 2.7-kg (6-lb) tests are analyzed to determine the effects of stemming methods on the fraction of material vented. The results of the four 907-kg (1-ton) detonations are also used to develop a relationship between iridium deposition and ionizing radiation dose rates from radioactive fallout.
