A pair of twin position-sensitive parallel plate avalanche counters have been developed at the Australian National University as a tracking system to aid in the further rejection of unwanted beam particles from a 6.5 T super conducting solenoid separator named SOLEROO. Their function is to track and identify each beam particle passing through the detectors on an event-by-event basis. In-beam st...
Evidence has been accumulating for the selective localization of radioactive plasma proteins in tumors. A number of clinical studies have shown that plasma proteins labeled with Il31 can be utilized for localization of hepatic metastases as well as primary cerebral neoplasms."'0"' Studies on localization of radioactive plasma proteins in animal tumors have been carried out by Babson and Winnick...
Abstract. Analysis of cosmogenic nuclides produced in surface rocks and sediments is a valuable tool for assessing the rates processes timing events that shaped Earth surface. The various are used have specific advantages limitations depend on time range over which they useful, type material not least feasibility analytical effort. Anticipating novel applications sciences, we develop situ-produ...
Gamma-scintigraphy is applied extensively in the development and evaluation of pharmaceutical delivery systems, particularly for monitoring formulations in the gastrointestinal and respiratory tracts. The radiolabelling is generally achieved by the incorporation of an appropriate radionuclide such as technetium-99m or indium-111 into the formulation or by addition of a non-radioactive iso...
Short-lived radioactive nuclei (SLR) with mean lives below ∼100 Myr provide us unique insights into current galactic nucleosynthetic events, as well events that contributed to the material of our solar system more 4.6 Gyr ago. Here we present a statistical analysis ratios these at time early (ESS) using both analytical derivations and Monte Carlo methods. We aim understand interplay between pro...
