1. A method for route planning utilizing a Global Positioning System (GPS) device to reduce cumulative exposure of a person travelling in a vehicle to radiation that is received from at least one natural sources of radiation from an environment along a plurality of available routes over a period of time, the method comprising:
receiving an origin and a destination, by at least one processor of the GPS device, for the vehicle; generating, by the at least one processor, from a map database, the plurality of available routes from the origin to the destination; retrieving radiation information about the at least one natural sources of radiation from the environment along each of the plurality of available routes, by the at least one processor, from a radiation database, the radiation database including historical radiation information, altitude radiation, and solar radiation forecasts provided by either a space weather service or a solar observatory, wherein the at least one natural sources of radiation is selected from the group consisting of Galactic Cosmic Rays (GCR), Solar Energetic Particle (SEP), radon and granitic elements; retrieving a personal profile including routing preferences and a cumulative radiation score based on previous trips and a maximum allowable radiation exposure level for the person for the time period; determining at least one of a health status of the person in the vehicle; in response to the 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 the each of the plurality of available routes, wherein calculating the radiation score for the each of the plurality of available routes includes estimating radiation levels from the at least one natural sources of radiation from the environment along the 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 the calculating, by the at least one processor, the radiation score for the each of the plurality of available routes, estimating, by the at least one processor, the cumulative exposure to radiation for the person going to receive from the at least one natural sources of radiation from the environment while travelling along the each of the plurality of available routes; in response to the estimating, by the at least one processor, the cumulative exposure to radiation the at least one natural sources of radiation from the environment for the person, presenting one optimal route on a display screen based on the at least one of the health status of the person, an expected travel time and the radiation score for the each of the plurality of available routes; monitoring, by the at least one processor, the cumulative exposure to radiation from the at least one natural sources of radiation from the environment in real-time and provide on the display screen real-time guidance along the optimal route for the person; and when the cumulative exposure from the at least one natural sources of radiation from the environment in real-time along the optimal route is predicted to exceed the cumulative radiation score retrieved from the personal profile for the time period, by the at least one processor, generate a warning to the person and provide on the display screen a real-time route guidance for the vehicle to re-route the vehicle based on radiation level, traffic or weather. |
