The fundamentals of methods in nuclear geophysics and their practical
applications in engineering geology, hydrology, hydrogeology,
agriculture and environmental science are discussed in this book. The
methods and apparatus based on absorption and scattering of gamma and
neutron radiation for determination of density and soil moisture in
natural conditions are presented in Chapters 2, 3, and 4. The
theoretical fundamentals and installations of the penetration logging
techniques where gamma, gamma-gamma and neutron logging in combination
with static penetration form common complexes for engineering geology
and hydrogeology exploration without boring holes are described. The
developed constructions and practical use penetration logging
installations for applications on land and marine shelves are described
in Chapters 5, 6, 7, and 8. The physical fundamentals for the use of the
natural stable and radioactive isotopes for study of the global
hydrological cycle are provided. The experimental data, origin and
distribution of cosmogenic and radiogenic isotopes in the oceans,
atmospheric moisture, surface and underground waters are presented in
Chapters 9, 10, and 11. The sources and conditions of the radioactive
contamination of the natural waters are discussed in Chapters 12 and 13.
This book will be of interest to scientists and researchers who use
nuclear geophysics methods in engineering geology, hydrology,
hydrogeology and hydrogeoecology. Lecturers, students, and postgraduates
in these subjects will also find it useful.
