Abstract:
For many years coastal scientists and engineers have attempted to label sedimentary particles in order that their movement paths might be determined. Several attempts have been made at the Beach Erosion Board, none of which met with any measure of success. Furthermore, inherent in this system is an extensive sampling program and arduous identification of the labeled particles. Recently, however, the labeling of natural sediments or simulated sediments with radioisotopes as tracers has proved successful and a long sought goal has been achieved.

AbstractProcedures of site investigation included in BS 5930:1981 concentrate on obtaining information on ground conditions near proposed structures. Groundwater flow paths, however, are often influenced by hydrogeological conditions well beyond the area and tracer tests have been found a useful addition to investigations.Different types of groundwater tracers are described and their uses in establishing groundwater flow paths and other hydrogeological characteristics of some regimes are outlined. Precautions are always necessary when using tracers, however, and these are especially stringent

Abstract:
Tracer techniques have been central in studies of transport in plants. In the case of carbon, the only readily available radioactive tracer has been 14C, although 11C was used for a short time before 14C could be made. Tracers have usually had to be measured by destructive harvesting of the plant, giving a practical limit to the data resolution in both time and space. A major advantage of the short-lived, positron-emitting tracers, of which 11C is one example, is that in vivo measurement is possible, giving detailed time series of tracer data in many locations and opening up powerful new techn

Abstract:
Although negative hepatic glucose production rates are physiologically impossible, they have been observed when hepatic glucose production is measured with the tracer-dilution technique during the hyperinsulinemic, euglycemic glucose clamp. Because hepatic glucose production is determined from the difference between tracer-derived glucose disposal and the known exogenous glucose infusion rate, the negative values for hepatic glucose production must result from an underestimation of glucose disposal by the tracer technique. In the current investigation, tracer-derived glucose disposal was measu

Abstract:
In contrast to "weightless" radioactive tracers, stable isotope tracers have nonnegligible mass and are naturally present in the system, and the measured variable is a ratio of two isotopic species. These features do not allow stable isotopic tracer data analysis using straightforward analogy with radioactive tracer approaches, even though this practice is common. In this study, we present kinetic variables, models, and measurements for the analysis and interpretation of stable isotope tracer data.

The present review discusses the advantages and limitations of using stable-isotope tracers to assess carbohydrate and fat metabolism at the whole-body level. One advantage of stable-(v. radioactive-) isotope tracers is the relative ease with which the location of a label within a molecule can be determined using selected-ion-monitoring GC-mass spectrometry (SIM-GC- MS). This technique minimizes potential problems due to label recycling, allows the use of multiple-labelled compounds simultaneously (e.g. to quantify glucose cycling), and perhaps most importantly, has led to the development of u

Abstract:
Sputtering yields of cobalt and chromium by argon and xenon ions with energies below 50 eV are reported. The targets were electroplated on copper substrates. Measurable sputtering yields were obtained from cobalt with ion energies as low as 10 eV. The ion beams were produced by an ion gun. A radioactive tracer technique was used for the quantitative measurement of the sputtering yield.57Co and 51Cr were used as tracers. The yield–energy curves are observed to be concave, which brings into question the practice of finding threshold energies by linear extrapolation.

Abstract:
Thyroid imaging with radio-isotopes of iodine provides functional and quantitative information. Images, scans, or scintiscans are the terms used for the pictures that are obtained. In general, a radionuclide or radiopharmaceutical is administered orally or intravenously and images of the distribution of the radioactive tracer are obtained after specific times using a gamma camera. Some clinicians employ a rectilinear scanner rather than a gamma camera to produce the images, but this should not be considered state of the art. Scintiscans do not have the resolution of ultrasonography, CT, or MRI, but they provide reasonable anatomical information as well as functional information. A numerical uptake measurement of how much of the tracer has been trapped can be obtained at the same time as the scintiscan to provide complementary quantitative information. Imaging with radio-iodine is of great value in the diagnosis and management of patients with thyrotoxicosis and differentiated thyroid cancer. It is of less value in thyroid nodules, hypothyroidism, simple goitre, and undifferentiated thyroid cancer. The chapter starts with a discussion of the radioactive tracers and the methods for scanning. Then the appearance of a normal scan followed by findings in patients with thyrotoxicosis, simple goitre, nodular goitre, and congenital defects are described. In these situations the scintiscan evaluates the region of the thyroid. Finally, the role of nuclear medicine imaging in patients with cancer of the thyroid is presented separately since the imaging is different in that it usually evaluates the whole body.

Abstract:
Abstract Successful hydraulic fracturing is critical for hydrocarbon recovery from tight reservoirs. Fracture geometry is one essential quality indicator of the created fracture. The geometry provides information about the size of the created fracture and containment and verifies the pre-job modeling. Different techniques are applied to determine fracture geometry, and each has its own advantages and limitations. Due to its simplicity, the radioactive tracer log is commonly used to determine fracture placement and fracture height. Its main drawbacks include shallow depth of investigation, time

Abstract:
Despite the advance of sustainable practice and energy efficient techniques outside of the nuclear industry, at the start of the 21st Century there was a lack of published guidance aimed at their adoption at specifically nuclear facilities. Even with the establishment of the Nuclear Decommissioning Authority, there is very little guidance published on how to adopt sustainable practices during decommissioning. There have been instances where energy efficiency had affected design and operations decisions. Projects aimed at responsible housekeeping, switching off lights, and changes to the nuclea
