Detection of Radioactivity in Transit Stations - Phase 2

The purpose of this Innovations Deserving Exploratory Analysis (IDEA) project was to test and evaluate a prototype system to detect dangerous levels of radioactivity in rail transit stations. A prototype system was installed into the Medical Center Metrorail station of the Washington Metropolitan Area Transit Authority (WMATA); it has been running since its installation on January 13, 2009. The data collection allowed the authors to measure the achieved sensitivity and to evaluate it against various concepts of operations (CONOPS). Use of the preexisting security cameras and network infrastructure will greatly reduce cost and facilitate broad coverage. The work performed under this contract was with digital cameras on digital networks only. Modifying the algorithms to work with analog network connections, however, was determined to be straightforward to implement. Transit stations are potential targets for terrorist attacks because they serve large numbers of people daily. To protect against that threat, pervasive radiation detection is needed at all times. Transit systems pose special detection problems due to limited line-of-sight areas in transit stations arising from radiation blocking obstructions, e.g., concrete, steel, and earthen walls and supports. In this report, the authors discuss the results achieved by Advanced Fuel Research, Inc., to address these concerns.
