The time-invariant fractional transfer rates, which describe the transport of I between environmental compartments comprising the atmosphere, hydrosphere, lithosphere, and terrestrial biosphere Cited by: The U.S. Department of Energy's Office of Scientific and Technical Information. Iodine ( I) is a long-lived radioisotope of iodine which occurs naturally, but also is of special interest in the monitoring and effects of man-made nuclear fission decay products, where it serves as both tracer and potential radiological contaminant. Formation and decay. Long.

  This report is one of the five biosphere reports that develop input parameter values for the biosphere model. The ''Biosphere Model Report'' (BSC [DIRS ]) describes the conceptual model, as well as the mathematical model and its input parameters. Figure is a graphical representation of the documentation hierarchy for the ERMYN.   The use of a well-defined database allowed detailed comparisons of FEPs for trans-port as well as for the calculation of exposure pathways. Results have indicated not only the common basis in many model descriptions but also where further development and consolidation are required. This paper summarises some of the key findings from the study.   The degree of agreement between the detailed and insight model results for uranium and chlorine is very similar to that for caesium and iodine For palladium (a radionuclide that is solubility limited in many model realisations) the results show a similar degree of agreement to those for selenium Calculation Model for the Impact on Soil Due to Tritium Emission into the Atmosphere During Snowfall. Biosphere Model Validation by Intercomparison to Observed Behaviour of Fallout Radionuclides in the Aquatic Environment. The book is composed such as to give the reader the chance to quietly study the presented papers in good order.

Calculation Model for the Impact on Soil Due to Tritium Emission into the Atmosphere During Snowfall. Biosphere Model Validation by Intercomparison to Observed Behaviour of Fallout Radionuclides in the Aquatic Environment. The model simulations presented here demonstrate the utility of a land surface model that simulates the isotopic contents of H 2 O and CO 2 ecosystem pools and fluxes. This utility is apparent because of the many non-linear processes that affect the 18 O of soil and leaf water as well as the dynamics of gross carbon exchanges between the land.   To evaluate the underlying determinants of variations in the TVX metrics, model calculations were compiled for a typical day, with the diurnal forcing from midlatitude summer meteorological conditions for the HAPEX-Mobilhy site, including soil moisture, IR, temperature, and wind at the reference height. Precipitation was set to 0 to constrain. The "Combined Energy and Biosphere Model" CEBM has been developed as a tool for the calculation of the atmospheric CO2 content as a result of an intensive use of biomass for energy purposes.
