[en] When a package is shipped, people who work, live or travel in the route used for transportation of radioactive materials are irradiated, as well as those who are inside vehicles that travel in the same or opposite directions. Therefore, the proposed work has as main objective to estimate the radiological impact of the transportation of radiopharmaceuticals of IPEN-CNEN/SP to some predefined destinations. The doses were estimated for drivers, from both the operation of driving the vehicle, and the loading and unloading of packages, because these tasks are performed by the drivers. The calculations were carried out from information obtained in the activities of transport of radiopharmaceuticals, such as: number of packaged transported, number of trips, number of workers involved, average time of loading, unloading and transport, in addition to the measures obtained in the monitoring performed in packages and means of transport.
