In addition, risk models that are too simple or based on old data can produce inaccurate results. Phases of probabilistic risk assessment include release assessment, exposure assessment, consequence assessment, and risk estimation. Using the Composite Risk Model to Obtain Risk Estimates Release assessment allows you to investigate the potential for technologies, products, processes, or systems to release risk agents into the environment. Risk agents include chemicals, biological agents, physical agents, and energy. Mathematical models are used to simulate the behavior of a risk source.
Statistical tools transform measurements into predictions of future behavior.
Exposure assessment helps determine what happens to risk agents once they are released into the environment. This type of assessment focuses on population subgroups, such as children, and their behaviors, such as food-consumption practices. Consequence assessment identifies the relationship between exposure to a risk agent and the health and environmental consequences. Risk agents have a wide range of effects on human health and the environment. Numerous tests can be performed to determine the effects of an exposure.
