This paper describes a dynamic compartment model to predict the time-dependent 14C activity in a plant as a result of adirect exposure to an amount of 14CO2for a short period of time, and experimental results for the model validation. In the model, theplant consists of two compartments of the body and ears, and five carbon fluxes between the compartments, which are the function ofparameters relating to the growth and photosynthesis of a plant, are considered. Model predictions were made for an investigation intothe effects of the exposure time, the elapsed exposure time, and the model parameters on the 14C radioactivity of a plant. The presentmodel converged to a region where the specific activity model is applicable when the elapsed time of the exposure was extended up tothe harvest time of a plant. The 14C activity of a plant was predicted to be the greatest when the exposure had happened in the periodbetween the flowering and ears-maturity on account of the most vigorous photosynthesis rate for the period. Comparison of modelpredictions with the observed 14C radioactivity of rice plants showed that the present model could predict the 14C radioactivity of the riceplants reasonably well.
