Radiation exposure of airline crew members to the atmospheric ionizing radiation environment

A study of radiation exposures in the ionizing radiation environment of the atmosphere is currently in progress for the Italian civil aviation flight personnel. After a description of the considered data sources, the philosophy of the study is presented, and an overview is given of the data processing with regard to flight routes, the computational techniques for radiation dose evaluation along the flight paths and for the exposure matrix building, along with an indication of the results that the study should provide.
