Radioisotopes produced by neutron irradiation of food.
The use of neutrons for cargo interrogation has the potential to drastically improve threat detection. Previous research has focussed on the production of (24)Na, based on the isotopes produced in pharmaceuticals and medical devices. For both the total activity and the ingestion dose we show that a variety of isotopes contribute and that (24)Na is only dominant under certain conditions. The com...
متن کاملComparison of stable isotopes and radioisotopes in the measurement of iron absorption in healthy women.
1. Stable isotope methods are being used to investigate the absorption of dietary iron. In order to be certain that this new methodology is accurate, we have compared results obtained using stable isotopes and inductively coupled plasma mass spectrometry with those determined using a radioisotope and whole body counting. 2. The stable isotope 54Fe (2.8 mg) was given to 10 healthy non-pregnant w...
متن کاملCyclotron Produced Isotopes for Medical Applications
Cyclotron produced isotopes for medical use are classifiable as single photon emitters (201Tl, 123J, ~7Ga), used for planar and tomographic imaging (=SPECT), and as positron emitters (l8F, l~O, 13N, llC) as applied for tomographic organ imaging (=PET). There is a number of generator produced positron emitters. This paper reviews the application in clinical nuclear medicine for cardiology (myoca...
متن کاملCharacterizing a Two-channel Phoswich Detector Using Radioxenon Isotopes Produced in the Oregon State University Triga Reactor
Low concentrations of radioxenon isotopes can be measured with a high sensitivity using beta/gamma coincidence technique. In this technique, a coincidence event is recorded when two signals from beta and gamma detection channels are detected simultaneously. These two coincident signals are then processed to establish a two-dimensional beta/gamma coincidence spectrum in which the four radioxenon...
متن کاملNew Approaches to Produced Water Sampling, Analysis, and Remediation at ORNL
Oil and natural gas production is often accompanied by large amounts of wastewater [1]. The volumetric ratio of water-to-oil will increase over the lifetime of an operation and can eventually exceed 90%. Water is also associated with some, but not all, gas production. For instance, dry sources of gas are found in Alberta, Canada. Produced water is often reinjected into the well to increase oil ...
