Abstract:This paper presents imaging and modeling aspects of an interdisciplinary study of subsurface pollution and environmental remediation. F18 -FDG PET and Tc99m -NaTcO 4 SPECT studie s were performed to follow dynamic changes in the radiotracer distribution in model systems. Radioisotope solution was pumped through the test columns filled with sand or sediment in order to reproduce subsurface conditions of groundwater flow through satu rated sediment layers. Dynamic sequences of the radiotracer distribution were a… Show more
