Application of Environmental Radionuclides in Radiochronology

Abstract

A review concerning the application of naturally-occurring environmental radionuclides in radio-chronol. applications is given. Topics discussed include: radio-chronol. general concept; radiocarbon (origin, natural cycle, 13C and its behavior; 14C open and closed systems and dynamic equil.; concept; age; calcg. age; age precision; dating limits; base conditions affecting dating; sample collection, pretreatment, storage; factors affecting dating; calibration; reporting); 3H (atm. and hydrosphere, environmental tracer, water sampling for 3H analyses); radiocarbon and 3H dating (relative and abs. dating, archeol., geol., hydrol., environmental problems, technol.); other radionuclide dating methods (32Si, 39Ar, 85Kr); Kr-Ar and Ar-Ar dating; Rb-Sr dating; Sm-Nd dating; U-Th-Pb dating; Re-Os dating; Lu-Hf dating (chem. properties, radioactive decay, isotopic abundance; concept; anal. techniques; applicability and limitations; examples).
