Can xenon 129 occur naturally?
Isotopes. Naturally occurring xenon is composed of seven stable isotopes: 126Xe, 128–132Xe, and 134Xe. Nuclei of two of the stable isotopes of xenon, 129Xe and 131Xe, have non-zero intrinsic angular momenta (nuclear spins, suitable for nuclear magnetic resonance).
How do you identify a nuclear explosion?
There are many different ways to detect a nuclear detonation, these include seismic, hydroacoustic, and infrasound detection, air sampling, and satellites. They have their own weaknesses and strengths, as well as different utilities.

Is xenon gas legal?
The World Anti-Doping Agency has added inhalable forms of the gases xenon and argon to its list of banned substances after research determined the gases help the human body produce erythropoieten, or EPO, inside the games reports. …
Is XE 131 radioactive?
Xe-131 m has the longest half-life of the four radioxenon isotopes under study. It is produced with low independent yield from nuclear explosions but can be present in airborne samples as a result of in-growth from the decay chain. Normal operational releases occur from medical facilities or nuclear reactors.
How is Xenon used as a fuel in an ion drive?
In an ion drive, the xenon isn’t a fuel. It isn’t combusted, and it has no inherent properties that make it useful as a fuel. The energy source for an ion drive has to come from somewhere else. This source can be electricity from solar cells, or electricity generated from decay heat from a nuclear material.
How is the detection of an explosion done?
Detection consists of recognizing that a seismic event has occurred and locating the source of the seismic signal. Identification involves discriminating whether the source was an earthquake, or an explosion. In addition, the monitoring system must be able to perform these tasks despite any plausible attempts to evade the monitoring system.
How are ion thrusters used in space exploration?
Chemical explosions emit energy much more rapidly than any solar or nuclear power plant. Human space travel needs to be more rapid than what ion thrusters can provide. However, ion thrusters can be used to pre-deploy equipment, and chemical fuel to be used for fast travel when needed.
Are there any space missions using ion propulsion?
Missions using ion propulsion include NASA’s Dawn mission, the Japanese Hayabusa mission to asteroid 25143 Itokawa, and the upcoming ESA missions Bepicolombo, which will head to Mercury in 2017, and LISA Pathfinder, which will study low frequency gravitational waves.
