APPLICABILITY OF GEOPHYSICAL METHODS FOR DETECTION OF RADIONUCLIDES TRANSFER STRUCTURES

Abstract

The paper studies the issues of mapping of hydrodynamic structures, both natural and technogenic ones, including the ones transferring radionuclides remotely by using electrical survey methods of apparent electrical resistivity (AR) and self-potential (SP). At that it has been taken into account that modern distribution of radionuclides from the foci of underground nuclear explosions (UNE) takes place mostly with underground waters. AR and SP methods allow to detect natural and technogenic crushed zones as well as establish the presence of underground water flows in them. The presence and location of water flows with radioactive contamination is established by measuring the tritium exhalation based on a methodology developed at the Institute of Geophysical Research. Examples are presented for the joined interpretation of AR, SP and tritium exhalation methods data that prove the applicability of the technique to detect hydrodynamic structures, including the ones transferring radionuclides.
