Survey on ground water by gamma-ray measurement in civil engineering works

Journal Article:

Abstract

In the fractured zones where ground water exists, the water permeability is generally large, so that the radioactive elements in the depths of the earth rise relatively easily. The high intensity of the gamma-ray from such elements is thus exhibited in the air. A survey on ground water made possible in this way by the aerial method using a helicopter is described. The method has various advantages including the free setting of courses of traverse, low-speed flying at low altitude, which raises the survey accuracy, communication with those on the ground by easy landing, and reduction in survey time. As actual instances, the following surveys are given: mountainous tunnel and water gushing, the permeability of a dam foundation, fractured zones such as collapse and landslide, and mountainous water sources.
