TECHNIQUE OF SAFE HANDLING OF RADIOACTIVE RADIATION SOURCES WHILE CONDUCTING GEOPHYSICAL STUDIES OF HOLES AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 2002 - IPC

FIELD: geophysical examination of holes with use of radioactive sources. SUBSTANCE: separable rod of down-hole logging instrument is charged by radiation source in advance, is placed into container and transported to working site in package shipping container.
