    Less atmosphere between you and the source.

    The source being solar radiation (high energy particles (HEP) such as protons and electrons) and cosmic radiation (higher energy protons, various nuclei, and electrons), and the secondary particles from nuclear reactions between the solar and cosmic radiation (HEP) and the gas atoms in the atmosphere.
