Disease incidence or mortality) per number of events or dose of agent. , dose) of the agent. Acquiring this information depends on a number of factors, including the availability of direct observations or experience and specificity and temporal coupling of events and outcomes. The risk of a fatal automobile accident is a straightforward example of how risks can be measured. Automobile accident records are readily available; traffic fatality data can also be obtained easily. The following serves as an example of a risk calculation.

The dose to a particular tissue determines the probability of adverse health effects in that tissue. If a particular agent is nephrotoxic, the agent will not cause damage provided there is no dose to the kidneys. For a dose to occur, the agent must penetrate the skin, cross the lung or gastrointestinal barrier, and accumulate in the target tissue (usually via the general circulation). The dose usually represents some fraction of the exposure since not all of the agent ultimately finds its way to the target tissue.

The Red Book also fails to consider risks in a comprehensive framework; it views target risks independently of other risks, and risks are evaluated on an agent-by-agent basis. In reality people are exposed to multiple agents simultaneously in both occupational and environmental settings. The Commission proposed a distinctive risk-management approach to guide risk assessment, risk communication, and risk reduction. Historically there has been little progress in developing a generally acceptable framework for making risk-management decisions.
