title: Factors affecting cosmic-ray doses at aircraft altitudes.
abstract: Cosmic rays make a significant, but not normally a dominant, contribution to the radiation dose of people all over the world. However, doses rise with altitude and the earth's magnetic field means that latitude also becomes important. Solar activity imposes a further, time dependent, variation. This article gives more details of these factors in the context of radiation protection as applied to air travel.
