Abstract

A model, EWAM (Energy Water Air Model), has been developed for predicting integrated food and water


ingestion, and inhalation rates for various age and sex classes of humans. The model uses physical, physiological, nutritional and energetic relationships in combination with mass and energy balances. It involves specified activity time budgets and diets with one or more food types. The predicted ingestion and inhalation rates can be readily used for dose calculations in environmental assessment models for nuclear power installations.
