Predicted RRR values for the small, medium, and large patients. The LNT risk model was used to calculated baseline RRR values, and uncertainties in the dose determination, neutron w̅R , and risk models were applied to the baseline LNT RRR values to provide a 68% confidence interval. It can be seen that the uncertainties are asymmetric, which resulted from the asymmetric uncertainties in the risk models (eqs. 9 and 10).
