Abstract
The densities of mixtures of ordinary water and 18O enriched water have been measured all over the range of compositions, at temperatures between 293.15 and 313.15 K, using a vibrating-tube densitometer. From the error analysis of the density data in the 18O enriched water region (atom % 18O > 95) we concluded that densitometry measurements with an accuracy of ±0.00002 g cm−3, provide a simple, precise and low-cost method to determine the 18O enrichment degree of recycled heavy oxygen water used to generate radiopharmaceuticals, such as [18F]fluoro-2-deoxy-D-glucose for the Positron-Emission Tomography (PET) scanning.
期刊介绍:
Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria.
Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
