MEASUREMENT OF HYDRAULIC CONDUCTIVITY USING A RADIOACTIVE OR ACTIVATABLE TRACER
摘要
<p>A method of determining the distance, from a reference point, of a tracer emitting radiation comprising a first component emitted at a first known energy level and a second component emitted at a second known energy level, the intensity of a penetrating portion of the first component that penetrates a substance between the tracer and the reference point and the intensity of a penetrating portion of the second component of the radiation that penetrates the substance being a function of the rate of gamma radiation emission of the tracer as well as of the distance of the tracer from the reference point, the method comprising: a) measuring the intensity of the first penetrating portion and the intensity of the second penetrating portion; b) determining the ratio of the intensity of the first penetrating portion to the intensity of the second penetrating portion; and c) determining the distance of the tracer from the reference point.</p>
