Approaches to the Development of Engineering Models of Radiocarbon Migration in Water Bodies

A. L. Krylov, A. V. Nosov, and D. V. Aron

The issues of radiocarbon forecasting in surface land water are considered. Numerical estimates of radiocarbon specific activity values in surface water caused by natural sources, anthropogenic discharges, and emissions from NPPs are presented. The estimates are based on literature data on stable carbon and 14C measurements in air, water, and other components of water bodies. The estimates of the main parameters of biochemical migration of 14C in surface water are given. A need in taking into account the elimination biochemical cycle of 14C for modeling its migration is substantiated.
