A Liquid Xenon Radioisotope Camera [PDF]

IEEE Transactions on Nuclear Science, 1972
The increasing availability of short lived gamma and positron emitting isotopes, coupled with the importance of dynamical studies and better imaging, has generated the need for an improved ?-ray camera. We discuss a new type of ?-ray camera which makes use of electron avalanches in liquid xenon.

A Thermal Sublimation Generator of ^131mXe

Instruments, 2022
Stable and unstable isotopes of the heavy noble gas xenon find use in various medical applications. However, apart from 133Xe, used for Single Photon Emission Computed Tomography, radioactive isotopes of xenon are currently complicated to obtain in small

Beta-efficiency of a typical gas-flow ionization chamber using GEANT4 Monte Carlo simulations [PDF]

Nuclear Technology and Radiation Protection, 2011
GEANT4 based Monte Carlo simulations have been carried out for the determination of efficiency and conversion factors of a gas-flow ionization chamber for beta particles emitted by 86 different radioisotopes covering the average-b energy range of 5.69

Cosmogenic Activation in Double Beta Decay Experiments

Universe, 2020
Double beta decay is a very rare nuclear process and, therefore, experiments intended to detect it must be operated deep underground and in ultra-low background conditions. Long-lived radioisotopes produced by the previous exposure of materials to cosmic

Mapping the deposition of C137s and I131 in North America following the 2011 Fukushima Daiichi Reactor accident

Atmospheric Environment: X, 2020
The 2011 Fukushima Daiichi Reactor accident generated a large data set of global radionuclide observations. Frequent observations of xenon, caesium and iodine radioisotopes provided an opportunity to examine the performance of inter-continental scale ...

Separation of rare gases and chiral molecules by selective binding in porous organic cages [PDF]

, 2014
The separation of molecules with similar size and shape is an important technological challenge. For example, rare gases can pose either an economic opportunity or an environmental hazard and there is a need to separate these spherical molecules ...

Determination of atmospheric concentrations of xenon radioisotopes. Progress report [PDF]

, 1995
Determination of radioactive xenon concentrations in the atmosphere over a two year period has been performed as part of a research program to develop real-time measurement capabilities. The initial measurements were made to develop, prove, and validate the authors technical approach, while the longer-term measurements are being undertaken to establish
