Radiation measurements onboard aircraft in the South Atlantic region

There has been considerable research on measurements and simulation of the cosmic radiation doses for aircrew. Most of this was made in the northern hemisphere and on routes between Europe, Asia and North America. The current work shows the results of measurements made onboard a military aircraft specifically in the South Atlantic Anomaly Region, comparing some active and passive instruments and the results from computational dose estimation with special concern about possible effects from the anomaly on the radiation doses. - Highlights: • We took measurements of cosmic radiation aboard aircrafts in SAMA region. • We compared measurements with results from computational codes. • The flights missions were dedicated for these measurements and very well controlled.
