Probability of Causation (PC)
Once a case is filed under the Energy Employees Occupational Illness Compensation Program Act of 2000 (the Act or EEOICPA; 42 U.S.C. 7384 et seq.), the Department of Labor (DOL) determines whether the employee worked at a covered facility during a covered time period and has a qualifying health condition.
If the qualifying health condition is cancer, DOL sends the case to NIOSH for dose reconstruction. NIOSH returns the case to DOL once it completes the dose reconstruction.
DOL will use the energy employee's personal characteristics, employment information, medical information, and dose reconstruction results to determine the Probability of Causation (PC)—that is, the likelihood that the worker's cancer was caused by exposure to radiation during employment.
If the PC is 50% or greater (if the cancer was at least as likely as not caused by their exposure during covered employment), the energy worker (or his or her survivors) is eligible for compensation from DOL: $150,000, plus medical benefits for surviving energy workers for their cancer treatment.

Probability of Causation: Final Rule
On May 2, 2002, the Department of Health and Human Services published its final rule on the guidelines the DOL uses to determine the PC. The guidelines rely on well-established science for determining radiation-related cancer risks. The guidelines describe how DOL will use the NIOSH Interactive RadioEpidemiological Program (NIOSH-IREP) to calculate a worker’s PC.
The rule covers these elements:
- Data required to estimate PC
- use of personal and medical information
- use of radiation dose information
- Requirements for risk models used to estimate PC
- use of cancer risk assessment models in NIOSH-IREP (a program used by DOL to calculate the PC)
- procedures for updating NIOSH-IREP
- Guidelines to estimate PC
- required use of NIOSH-IREP
- cancers requiring the use of NIOSH-IREP
- general guidelines for use of NIOSH-IREP
- guidelines for cancers for which primary site is unknown
- guidelines for leukemia
- guidelines for claims involving two or more primary cancers
- non-radiogenic cancers
Public Comments on the Probability of Causation Rule
The final rule on PC went into effect after the public the Advisory Board had the opportunity to comment. Comments can be found on the Public Docket for 42 CFR 81 (Probability of Causation) page of our website.
