UNDERGROUND POLLUTANT EXPLORATION METHOD AND UNDERGROUND POLLUTION DISTRIBUTION MONITORING METHOD - National Institute of Agricultural Engineering

Title:

UNDERGROUND POLLUTANT EXPLORATION METHOD AND UNDERGROUND POLLUTION DISTRIBUTION MONITORING METHOD

Document Type and Number:

Japanese Patent JP3734034

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide an underground pollutant exploration method and an underground pollution distribution monitoring method capable of acquiring a tomographic video of the ground by a borehole underground radar, and acquiring quickly and accurately the distribution position, the concentration or the like of an underground pollutant from the tomographic video.
SOLUTION: This underground pollution distribution monitoring method has a procedure for forming boreholes 11, 12 under the ground, a procedure for radiating an electromagnetic wave into the underground from a transmission means 2 arranged in the borehole, a procedure for receiving the electromagnetic wave radiated from the transmission means by a reception means 3 arranged in the borehole, a procedure for operating the tomographic video including the underground pollutant distribution by a received signal by the reception means, and a procedure for monitoring the pollutant distribution following the elapse of time by the change with time of the tomographic video.
