Environmental Assessment of the Thermal Neutron Activation Explosive DetectionSystem for Concourse Use at U.S. Airports

摘要

The document is an environmental assessment of a system designed to detect thepresence of explosives in checked airline baggage or cargo. The system is meant to be installed at the concourse or lobby ticketing areas of U.S. commercial airports and uses a sealed radioactive source of californium-252 to irradiate baggage items. The major impact of the use of the system arises from direct exposure of the public to scattered or leakage radiation from the source and to induced radioactivity in baggage items. Under normal operation and the most likely accident scenarios, the environmental impacts that would be created by the proposed licensing action would not be significant.
