It operates in three basic modes: Sigma: water saturation detected via thermal neutron decay; C/O: oil saturation detected with gamma spectroscopy
; and water flow: water velocity from oxygen activation.
Mullens, "NMIS plus gamma spectroscopy
for attributes of HEU, PU and HE detection," Nuclear Instruments and Methods in Physics Research Section B, vol.
The first of five chapters covers the basic properties of uranium and its common compounds, outlines the processes employed to use it for nuclear fuel, and describes the basis of analytical techniques used to characterize it, including atomic absorption and emission spectroscopy, X-ray fluorescence spectrometry, neutron activation analysis, gamma spectroscopy
, electron microscopy, mass spectrometry, alpha spectrometry, and miscellaneous spectroscopic and ion counting techniques.
Muscat, June 2 (ONA) The Sultanate represented by the Ministry of Regional Municipalities and Water Resources will take part in the training course on the use of Monte Carlo Stimulation method for measuring radioactive contamination in "Gamma Spectroscopy
", to be executed in Tunisia tomorrow "Monday" by the Arab Organization for Atomic Energy in conjunction with the National Centre for Nuclear Science and Technology in Tunisia.
A comprehensive characterisation campaign was undertaken including surveys, sampling and gamma spectroscopy
in order to fully understand the radiological conditions.
For one core per reservoir, gamma spectroscopy
was used to determine the activity of [.sup.137.Cs] in the cores.
Among the concerns are isomers and gamma spectroscopy
, fundamental physics, nuclear astrophysics, reactions with neutron-rich nuclei, nuclear structure at 0+ states, the application and development of nuclear techniques, high spin experiments, and the theory of nuclear structure.
Samples were then separated by tissue and species, homogenized with a commercial food processor, and placed into a 500 mL or 1000 mL high-density polyethylene Marinelli beaker (Gamma Associates) designed for direct gamma spectroscopy
. The beakers were labeled, sealed, frozen, and shipped to the Environmental Sciences Division, Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee.
