Backcalculating cleanup targets in probabilistic risk assessments when the acceptability of cancer risk is defined under different risk management policies

When evaluating a fully probabilistic risk assessment, say at a hazardous waste site, the risk manager needs a risk management policy that distinguishes an acceptable distribution of risk from an unacceptable one. This manuscript explores several alternative ways to define the acceptability of a distribution of risk. This manuscript also presents methods to backcalculate distributions for cleanup targets under the alternative risk management policies if the need arises.
