3 He was originally touted as the better gas for hyperpolarized gas MRI because it is more polarizable and has no effects on the body. [1] However, 3 He is mostly produced by the beta decay of tritium (3 H), which is a product of nuclear warhead production. Additionally, 3 He is widely used by the U.S. military to detect smuggled plutonium. [14]
Xenon isotope geochemistry uses the abundance of xenon (Xe) isotopes and total xenon to investigate how Xe has been generated, transported, fractionated, and distributed in planetary systems. Xe has nine stable or very long-lived isotopes. Radiogenic 129 Xe and fissiogenic 131,132,134,136 Xe isotopes are of special interest in geochemical ...

Xenon-136 is an isotope of xenon that undergoes double beta decay to barium-136 with a very long half-life of 2.11 × 10 21 years, more than 10 orders of magnitude longer than the age of the universe ((13.799 ± 0.021) × 10 9 years). It is being used in the Enriched Xenon Observatory experiment to search for neutrinoless double beta decay.
Biosensors International also licenses its proprietary drug-eluting stent technologies to other medical device companies and specialty stent providers, including Terumo, Devax, Inc., and Xtent, Inc. Biosensors International Group has a joint-venture in Hong Kong listed as Shandong Weigao to market and distribute coronary stents in China. [1]
Because of its scarcity, xenon is much more expensive than the lighter noble gases—approximate prices for the purchase of small quantities in Europe in 1999 were 10 €/L (=~€1.7/g) for xenon, 1 €/L (=~€0.27/g) for krypton, and 0.20 €/L (=~€0.22/g) for neon, [67] while the much more plentiful argon, which makes up over 1% by volume ...
To increase the nuclear spin polarization of either 3 He or 129 Xe, two processes are involved: 1) optical pumping and 2) spin exchange. [ 23 ] [ 24 ] Hyperpolarized gas MRI is a technique that uses the alignment of nuclear spins in certain gases, such as 3 He or 129 Xe, to create detailed images of the body's internal structures.
Super Sonic Strike Missile (3SM) Tyrfing is a supersonic anti-ship missile under development by the Norwegian firm Kongsberg Defense & Aerospace (KDA). The missile is expected to be delivered from 2035 and is planned to be used on Norwegian and German naval vessels . [ 3 ]
