Single stage ECR ion source for the mass separation of xenon radioisotopes

Review of Scientific Instruments, 1990
The main features of ECR ion sources (high efficiency, almost unlimited lifetime, stable running conditions, low ion energy spread) make them, when optimized for a high yield at charge state 1+, ideally suited for on-line mass separation. For this reason a single stage 6.4 GHz test source was built for the Paul Scherrer Institute medical radioisotope ...

Radioisotopes of iodine and xenon of masses 120 and 121

Journal of Inorganic and Nuclear Chemistry, 1965
Abstract A new 43 ± 3 min 120 Xe has been produced by spallation of I with 340 MeV protons. New values for the half-lives of 120 I, 121 Xe and 121 I have been determined. Positron and gamma ray energies have been measured.

Design of Solid Form Xenon-124 Target for Producing I-123 Radioisotope Using Computer Simulation Techniques

Volume 3: Structural Integrity; Nuclear Engineering Advances; Next Generation Systems; Near Term Deployment and Promotion of Nuclear Energy, 2006
One of the most famous radioisotopes used in nuclear medicine is Iodine-123. Among the various types of nuclear reactions for producing I-123, the following reactions are favored due to the absence of I-124 and I-125 impurities: 54124Xe(P,2n)55123Cs5.9minβ+54123Xe2.08hrβ+53123I54124Xe(P,pn)54123Xe2.08hrβ+53123I Recently in Cyclotron and Nuclear ...

Vitality testing of teeth with a radiation probe using ¹³³xenon radioisotope

Dental Traumatology, 1986
Abstract The purpose of this investigation was to determine if the radioisotope 133xenon in saline injected into the periodontium would enter the blood circulation of the pulp and be picked up by means of a radiation probe placed in contact with the crown of the tooth.

Excitation Functions for the Formation of some Radioisotopes of Cesium and Iodine in Proton and Deuteron Induced Nuclear Reactions on Natural Xenon

ract, 1989
Excitation functions were measured using the 'stacked gas cell' technique for the fomation of {sup 127,129,132,134,136}Cs and {sup 124,126,130,131,133I} from natural xenon in proton induced reactions over the energy range of 9 to 43 MeV, and for {sup 127,129,132}Cs and {sup 124,126,130,131,133}I from in deuteron induced reactions over 22 to 53 MeV ...

CALIBRATION OF THE LUX-ZEPLIN DUAL-PHASE XENON TIME PROJECTION CHAMBER WITH INTERNALLY INJECTED RADIOISOTOPES

2022
Self-shielding in ton-scale liquid xenon (LXe) detectors presents a unique challenge for calibrating detector response to interactions in the detector's innermost volume. Calibration radioisotopes must be injected directly into the LXe to reach the central volume, where they must either decay away with a short half life or be purified out.

[Respiratory function in liver cirrhosis. Spirometry, blood gas analysis and radioisotope study with Xenon 133].

Minerva medica, 1975
The literature data concerning respiratory function in cirrhosis of the liver are cited and reference is made to the results of a spirometric, gas analysis and 133-Xenon investigation of this parameter in 38 patients. Spirometry pointed to slight ventilatory incapacity of the restrictive type.

Combined technetium radioisotope penile plethysmography and xenon washout: a technique for evaluating corpora cavernosal inflow and outflow during early tumescence.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1991
Combined technetium radioisotope penile plethysmography and xenon washout is a new technique that measures both corporal arterial inflow and venous sinusoidal outflow during early tumescence in patients with erectile dysfunction. Fourteen patients were studied using 99mTc-RBCs to measure inflow and 133Xe or 127Xe in saline to measure outflow ...
