Equations to Estimate Excess Relative Risk (ERR) for sources other than radon
Excess Relative Risk = Organ Equivalent Dose (Sv) x Risk Coefficients (ERR/Sv)
For more information, refer to the equation of Organ Equivalent Dose used in IREP to calculate probability of causation.
The risk coefficients are based on information obtained from the LSS cohort (Japanese survivors of the A-bomb), with the exception of thyroid cancer and radon exposures. The Japanese survivor data are adjusted for application to the U.S. population. Click on the "Risk Coefficients" node to view these adjustments.
