He earned a doctorate in physics in June 1949 with a thesis related to cosmic ray-mesotrons. He spent his summers working with Nobel Prize winner Earnest Orlando Lawrence's group at UC Berkeley. This research group moved to Livermore in the fall of 1952 to form what is now the Lawrence Livermore National Laboratory (LLNL). Germain rejoined this group full-time after the 1952-53. At LLNL, Germain designed fission weapons and took an active role in their testing in the Pacific Proving Grounds and later at the Nevada Test Site, when underground testing was required by the Limited Test Ban Treaty. In 1971, he supported the U.S. delegation in Geneva, Switzerland, engaging in the Strategic Arms Limitations Talks (SALT). He also led the Lab's efforts to contain all nuclear radiation underground, and in 1975, became the division leader of the Earth Sciences Division. In 1976, Germain transferred to the Los Alamos National Laboratory where his extensive knowledge and experience were leveraged in supporting a broad range of issues ranging from nuclear testing to geothermal energy and special projects for the laboratory director. Upon retiring from the national laboratories in 1985, he continued for several years as a consultant with R & D Associates on contracts with the Defense Nuclear Agency. James (Jack) Steven Kahn was a former Laboratory associate director. He received a bachelor's of science in geology from City College of New York, a master's degree in statistics from Pennsylvania State University and a Ph.D. in geophysics from the University of Chicago. Kahn began his career as a professor of geology at the University of Rhode Island in 1956. He left the university in 1960 to join the chemistry division at the Lawrence Livermore National Laboratory (then the Lawrence Radiation Laboratory). Kahn worked on the Pluto project, an attempt to build a nuclear-powered rocket and the Plowshare program, a project aimed at using nuclear explosives for civil applications. In 1971 he became the deputy leader of K Division. He next worked to establish the first Human Resources department at LLNL, and became the deputy associate director of Human Resources and Laboratory Relations in 1976. He followed that role as associate director for the nuclear test program in 1978, before moving to the position as the Laboratory associate director in 1980. As the Laboratory associate director, Kahn served as director in then-Director Roger Batzel's absence. The laboratory was founded as the University of California Radiation Laboratory in 1931 by Ernest Orlando Lawrence, a University of California Berkeley physicist who won the 1939 Nobel Prize in Physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It is a United States Department of Energy National Laboratory, operated by the University of California. In 1971, the name was changed to Lawrence Berkeley Laboratory and the Livermore campus became the Lawrence Livermore Laboratory. This document will deal with some aspects of the phenomenology of underground nuclear explosions. It is divided into four general sections. First, we shall examine the rather extensive history of routine underground explosions and note that, from a pragmatic point of view, a nuclear explosion can be contained by putting it underground. Those few cases where some radioactivity was released will be examined to see if they can be categorized or if there were extenuating circumstances. Second, we shall describe the calculation of early time phenomenology the interactions between a nuclear explosion and the media surrounding it during the first few tenths of a second after the explosion. We shall attempt to substantiate these calculations by showing how well they agree with actual.
