1. A method for route planning utilizing a Global Positioning System (GPS) device to reduce cumulative exposure to the device travelling in a vehicle to radiation along a plurality of available routes over a period of time, the method comprising:
providing a GPS device; providing an electronic device profile that quantifies the tolerance of the GPS device to exposure to radiation; receiving an origin and destination by at least one processor of the GPS device for the vehicle; determining a plurality of available routes between the origin and the destination; generating, by the at least one processor, from a map database the plurality of available routes from the origin to the destination; in response to generating, by the at least one processor, from the map database the plurality of available routes from the origin and the destination, calculating, by the at least one processor, a radiation score for each of the plurality of available routes along each of the plurality of available routes from the origin to the destination based on the retrieved radiation information from the radiation database; in response to calculating, by the at least one processor, the radiation score for each of the plurality of available routes, estimating, by the at least one processor, the cumulative exposure to radiation for the device going to receive from the radiation source while travelling along each of the plurality of available routes; in response to estimating, by the at least one processor, the cumulative exposure to radiation by the device, presenting one optimal route on a display screen based on the expected travel time and the radiation score for each of the plurality of available routes; and monitoring, by the at least one processor, the cumulative exposure to radiation in real-time and provide on the display screen real-time guidance along the optimal route for the GPS device. |
