Training requirements for chemists in radiotracer development for nuclear medicine

Finn, R.; Fowler, J. - 2008

This panel was organized to address the current and anticipated future shortage of chemists with advanced training to fill positions in the nuclear medicine field. Although hard data and statistics are difficult to acquire, we will attempt to highlight the impact of chemistry on nuclear medicine...

Scenarios for /sup 14/C release to the atmosphere by the world nuclear industry and estimated radiological impacts. [Projections for the years 1975 through 2020]

Till, J.E.; Killough, G.G. - 2009

This paper presents an assessment of the radiation dose to the world population and the associated potential health effects from three scenarios of /sup 14/C releases by the nuclear industry between 1975 and 2020. Measures of health impact are derived from source terms through the use of a...

Beryllium-10: Half-life and AMS-standards

Hofmann, H.J.; Beer, J.; Bonani, G.; von Gunten, H.R.; … - 2008

Absolute AMS measurements of /sup 10/Be require reliable standards for calibration. Among the existing standards, rather large differences have been observed. These differences were found partially to be due to the different half-life values which were assumed. Also for comparison of AMS data...

Evaluation of the data available for estimating release rates from commercial low-level waste packages

Sullivan, T.M.; Cowgill, M.G. - 2008

In this paper, an overview of our findings concerning the distribution of activity within low-level radioactive wastes will be presented. This will begin in a general fashion and consider the distribution of the total activity by each of the following: waste class, waste stream, wasteform, and...

GLOBAL RADIOLOGICAL SOURCE SORTING, TRACKING, AND MONITORING (GRADSSTRAM) USING EMERGING RFID AND WEB 2.0 TECHNOLOGIES TO PROVIDE TOTAL ASSET AND INFORMATION VISUALIZATION Paper at 2009 INMM

Walker, Randy M; Kopsick, Deborah A; Gorman, Bryan L; … - 2010

Background Thousands of shipments of radioisotopes developed in the United States (U.S.) are transported domestically … radioisotopes in commerce. ORNL was the pioneer of the international radioisotope shipping and production business. Most … radioisotopes made and used today were either made or discovered at ORNL. While most of the radioisotopes used in the commercial …

Uncertainty Analysis of Nondestructive Assay Measurements of Nuclear Waste

Blackwood, Larry Gene; Harker, Yale Deon - 2009

Regulatory agencies governing the disposal of nuclear waste require that the waste be appropriately characterized prior to disposition. The most important aspect of the characterization process, establishing radionuclide content, is often achieved by nondestructive assay (NDA). For NDA systems...
