An approach for quantifying biases and uncertainties in external dose measurements was developed, focusing on the kind of information needed for adjustment of epidemiologic dose response analyses. The approach evaluated biases and uncertainties in external dose estimates from each of several sources and combined them to obtain an overall assessment. An approach was developed and implemented for accounting for uncertainty in systemic bias in recorded external doses. The approach made it possible to account for a potentially important type of exposure uncertainty. The methods could be applied to any study where quantitative risk estimates expressed per unit of exposure are of interest. A model for uncertainties resulting from random variation in laboratory measurements and an approach for accounting for random uncertainties in estimates of cumulative external dose used in nuclear worker studies were developed. These were applied to dose response analyses based on Hanford worker radiation exposure data.
