A nuclear detonation detection system (NDDS) is a device or a series of devices that are able to indicate, and pinpoint a nuclear explosion has occurred as well as the direction of the explosion. The main purpose of these devices or systems was to verify compliance of countries that signed nuclear treaties such as the Partial Test Ban treaty of ...
Block IIIF satellites host a redesigned U.S. Nuclear Detonation Detection System (USNDS) capability that is both smaller and lighter than previous systems. [ 11 ] The USNDS is a worldwide system of space-based sensors and ground processing equipment designed to detect, identify, locate, characterize, and report nuclear detonations in the Earth ...
Vela started out as a small budget research program in 1959. It ended 26 years later as a successful, cost-effective military space system, which also provided scientific data on natural sources of space radiation. In the 1970s, the nuclear detection mission was taken over by the Defense Support Program (DSP) satellites.
The United States is continuing to plan for a nuclear detonation in a major city -- should it occur near you, here's what you should do. If a nuclear bomb goes off, this is the most important ...
When the device being tested is buried at sufficient depth, the nuclear explosion may be contained, with no release of radioactive materials to the atmosphere. The extreme heat and pressure of an underground nuclear explosion cause changes in the surrounding rock. The rock closest to the location of the test is vaporised, forming a cavity.
The name of the detector is a pun [3] which was bestowed upon it by Fred Reines, one of the scientists working on the project.The name is derived from the Hindi word "bhang", a locally grown variety of cannabis which is smoked or drunk to induce intoxicating effects, the joke being that one would have to be on drugs to believe the bhangmeter detectors would work properly.
The GE 477L Nuclear Detection and Reporting System (NUDETS, [1] NUDETS 477L, [2] Program 477L [citation needed]) was a Cold War "Nuclear Detonation and Radioactive Fall-out Reporting System" for the National Military Command System. [3] Planning/development began "by September 1, 1959, when NORAD had taken over responsibility from CONAD."
Project Mogul (sometimes referred to as Operation Mogul) was a top secret project by the US Army Air Forces involving microphones flown on high-altitude balloons, whose primary purpose was long-distance detection of sound waves generated by Soviet atomic bomb tests. The project was carried out from 1947 until early '49.
