FAQs: NIOSH-Interactive RadioEpidemiological Program (NIOSH-IREP)

To determine probability of causation for a cancer claim under The Act, DOL uses a computer software application NIOSH has developed in collaboration with the National Cancer Institute, called NIOSH-IREP. This computer software is a science-based tool that allows DOL to determine the probability a cancer was caused by a person’s radiation dose from nuclear weapons production work. The actual outcome of a claim depends on a number of important factors such as the dose estimates of past exposures and the type of cancer that has been diagnosed. DCAS is responsible for maintaining and updating this software and the scientific elements (cancer risk models) that it uses.
