Abstract: A method and system is provided for implementing an integrated detection and monitoring system. Aspects of the present invention include mounting at least detector into a vehicle to provide a mobile detector. The mobile detector is then transported to a security checkpoint and positioned along side a vehicle pass-through. As a vehicle passes through, the mobile detector scans the vehicles to detect levels of one or more designated materials. If any material detected exceeds a threshold alarm level, the detected level of the material is stored in a file that is associated with the vehicle, and the file is wirelessly transmitted to a command center to notify authorities.
