Background: The earlier Atomic Bomb explosion in Hiroshima and Nagasaki, and three worth mentioning nuclear accidents - detonation at Fukushima Daiichi nuclear plant, Chernobyl nuclear fallout and an accident at Three Mile Island nuclear power plant have made us more worried about the secure exploitation of nuclear energy.

Nuclear explosion produce immediate and delayed destructive effects, so identifying parameters has become inevitable for detecting nuclear tests conducted anywhere in the world. The energy evolved in a nuclear explosion is enormous, which is the characteristic and hence a vital parameter for a nuclear explosion detection. The proposed technique is to compute energy evolved out of an atmospheric...

An intercept mission with nuclear explosives is the only practical mitigation option against the most probable impact threat of near-Earth objects (NEOs) with a short warning time (e.g., much less than 10 years). Although a less destructive, standoff nuclear explosion can be employed in such a last minute intercept mission, the momentum/energy transfer created by a shallow subsurface nuclear ex...

In the past ten years, significant progress has been made in nuclear explosion monitoring (NEM) through research and development (R&D) with regard to detection, location and identification, however substantial improvements are yet possible. Today, there is increasing interest in both current and planned NEM R&D technology particularly in light of its relevance to the Comprehensive Nuclear-Test-...

It is remarkable that the most recent nuclear test explosion, by North Korea (2006 October 9), although quite small, was well-detected teleseismically. We describe how this event was promptly identified as an explosion and not an earthquake, on the basis of regionally recorded signals, in a region that apparently would have permitted such identification even if the test had been much smaller. T...
