Determination of optimum time interval of meteorological data used with atmospheric dose modeling at SRS
Measured tritium oxide concentrations in air were compared with calculated values using routine release Gaussian plume models for different time intervals of meteorological data. These comparisons determined an optimum time interval of meteorological data used with atmospheric dose models at the Savannah River Site (SRS). Meteorological data of varying time intervals (1 y to 10 y) were used for the comparison. Insignificant differences are seen in using a 1-y database as opposed to a 5-y database. Use of a 10-y database results in slightly higher or more conservative estimates. For meteorological databases of length 1 y to 5 y the mean ratio of predicted to measured tritium oxide concentrations is approximately 1.25 whereas for the 10-y database the ratio is closer to 1.35. Currently at the SRS a meteorological database of five year's duration is used for all dose models. This study suggests no substantially improved accuracy using shorter or longer time intervals.
