Tracer identification in fertilizer migration using neutron activation analysis
- Department of Chemical and Nuclear Engineering, University of Maryland College Park, MD 20742 (United States)
The Wye Institute of the University of Maryland is studying the migration of fertilizer into the Chesapeake Bay from the surrounding farm land. Several different methods of investigation have been looked into including neutron activation analysis. We have attempted to find some natural trace elements in the fertilizer to study the migration. Well and surface water samples were collected at various locations around tilled and until led fields. These samples were activated in the Maryland University Training Reactor at several different power levels and irradiation times and analyzed in a calibrated GeLi detector. The resulting spectra were normalized and plotted on transparencies which provided an easy method for spotting migration of trace elements. Several possible tracers were identified for use in a more detailed study at a later date. (author)
