Two bills were introduced to address port security issues. The first bill (S. 1400) was approved by the Senate but was not considered in the House. The bill would have established an integrated coastal-observation system with several goals, including fighting terrorism and monitoring storm activity. The system would also have collected data on the marine environment and ocean life. Another Senate bill (S. 193), which would have required that the Department of Energy evaluate radiation detection systems for use at U.S. seaports, failed to win approval in its Senate committee. The system would have been used to detect the presence of a dirty bomb being smuggled into the U.S. aboard a cargo vessel.
