Abstract
IT has recently been suggested that, in the values of remanent magnetization of clay bricks fired in ancient times, there exists evidence of a secular decrease in the strength of the Earth's magnetic field1,2. It has been further suggested that the effect of such a change in magnetic field on the intensity of cosmic radiation incident upon the Earth would tend to falsify radiocarbon dating procedures based on an assumed constant intensity of cosmic radiation3.
