Abstract
The purpose of this work was to examine possible implications of parameter uncertainties on the estimates of population exposure to 137Cs following the Goiania (Brazil) accident. The relevance of these uncertainties in decision making at the time of the accident and in outlining future research aimed at reducing the critical uncertainties was examined.The derived limit for soil removal used at the time of the Goiania accident by conservative deterministic simulation was shown to be the 92nd percentile value of the probabilistic simulation. The primary exposure pathway to the public was confirmed to be the external exposure from the contaminated soil.
