Sea Level Latitude Effect of Cosmic Radiation

Abstract
On a recent voyage from Rio de Janeiro to Boston the vertical intensity of the total and hard components of the cosmic radiation were measured with a Geiger counter telescope apparatus. For the hard component the percentage alteration from high latitudes to the magnetic equator was 5.32±0.46 percent. For the soft component it was 4.46±0.61 percent, and for the total radiation it was 5.04±0.55 percent.
