This thesis is concerned with near source primary seismic waves generated by, the Gnome, Hardhat, Shoal and Haymaker underground nuclear explosions. Records of ground motion between 0.3 and 20.0 kilometers from the sources were analyzed in terms of displacement amplitude and energy variations with distance. The observed data have been...
The first cycle of seismic waves recorded at distances of 45,
300 and 355 km. from the GNOME nuclear explosion was used to determine
whether the near source wave characteristics at 0.3 km.
could be determined from distance measurements. Both head wave
and body wave propagation were considered. First the...
Several radioxenon isotopes (¹³¹ᵐXe, ¹³³Xe, ¹³³ᵐXe, ¹³⁵Xe) are characteristic byproducts of nuclear explosions, and due to their chemically nonreactive nature can easily escape from tests occurring underground and enter the atmosphere. It has been shown that by utilizing beta-gamma coincidence techniques, the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) can...
