Abstract

The present invention relates systems and methods to determine the location information of a signal made from a radioactive device or hazardous material. The system employs multiple radiation sensor devices, which his capable of determining the signal strength and the angle of arrival of a radioactive signal. The mobile switching center sends a request along with radiation information to a location processor, which controls devices. The location processor sets up each sensor device to track the radiation signal. If at least two devices are successful in tracking the radioactive signals and returning information about the radiation signal, then the location processor can determine the location of the radioactive device or hazardous material by using a triangulation method.

Claims

10. A method for determining the location of a radioactive device or chemical/biological hazardous material from which notification to a Public Safety Answering Point is made, the method comprising:

receiving radiation signal information related to an emitting source from a mobile switching center;

receiving a location request from a mobile switching center;

sending radioactive signal information to a plurality of radiation sensor devices;

receiving angular information from at least two radiation sensor devices;

employing a triangulation method to calculate the location of the radioactive device or chemical/biological hazardous material;

transmitting information about the location to the mobile switching center;

obtaining geographical location information for the wireless transmission towers associated with at least two radiation sensor devices,

wherein the step of employing a triangulation method further comprises

determining a best pair of geographical coordinates by averaging geographical coordinates.
