Development of radionuclide detectors for use in capillary electrophoresis
The development of two radionuclide detection methods for capillary electrophoresis (CE) is described. The methods are used to determine the neuropeptide content of single neurons. The application of CE to single cell studies by several research groups is also reviewed with an emphasis on the …

Development of improved analysis of radionuclide images of aerosol deposition
… inhalation therapy via the simultaneous use of radionuclide imaging. However, due to limitations imposed by the technologies currently available, not enough information can be gathered in-vivo about the respiratory tract. Consequently, widespread use of anatomical models of the lung is being …

Coupling source term, mineral reactivity and flow in radionuclide transport
… simulations of waste glass dissolution and radionuclide release in a hypothetical near field were conducted over a time span of a million years with GoldSim. The results showed that enclosing the waste glass in a steel canister covered by a copper canister and emplacing the waste package in …

Radionuclide concentrations and radiation hazard assessment in the soil of Otjiwarongo, Namibia
… the activity concentrations of the primordial radionuclides 238U, 232Th, and 40K in the soil samples. The mean activity concentrations of the radionuclides in the ten geographical areas vary from 37.6 ± 7.4 to a high of 97.8 ± 46.2 Bq/kg for 238U, from 81.9 ± 16.7 to a very high of 852.8 ± …

Uranium-series radionuclide records of paleoceanographic and sedimentary changes in the Arctic Ocean
The radionuclides 231Pa and 230Th, produced in the water column and removed from the ocean by particle scavenging and burial in sediments, offer a means for paleoceanographers to examine past dynamics of both water column and sedimentary processes. I show for the first time that a state of balance …

Predictive modelling of external dose rate from radionuclide therapy patients following discharge from hospital
Background: Di erentiated thyroid carcinoma patients undergo thyroidectomy, followed by radiodine ablation in hypothyroid or euthyroid state. Several attempts were made to predict the external dose rate, however, there is a lack of accuracy in predictions from existing models of dose rate decay. …
