Abstract :
Accurate measurement of the underground fluctuations of radiation intensity has been undertaken. The radiation intensity is clearly correlated with the difference between the temperature on the ground surface and that underground. When the temperature at the surface is higher than that underground throughout the entire day, then the radiation intensity is consistently high.
