Radiometric methods for estimating potential nuclide migration rates from high-level nuclear waste repositories: present status and further research

This paper focuses on the application of radiometric techniques to high-level nuclear waste disposal problems and makes recommendations for future research. The author concludes that the following research areas have a high priority: 1)development of analytical techniques for Kr81 at natural levels; 2)further investigation of radiogenic noble-gas buildup in very old (greater than 106 years) groundwater systems; and 3)regional-scale studies to examine the relationships between hydraulic parameters, conservative-tracer transport, and sorbed tracer transport. 7 references
