title: Calculation of the uncertainty in the activity estimate for workers in the uranium industry.
abstract: This paper describes a methodology to calculate the uncertainty that may propagate during the uranium activity estimation for workers. An analytical expression was derived to find a relationship between measured activity and the chest wall thickness that is routinely measured for workers. The uncertainty in activity estimation was empirically calculated for 14 workers using their measured chest wall thicknesses collected over a 5 y time period.
