title: Estimation of cumulative exposures to ethylene oxide associated with hospital sterilizer operation.
abstract: The statistical distribution of exposures to ethylene oxide was estimated for a task involving transfer of materials from a hospital sterilizer. The exposure data are consistent with either a normal or log-normal distribution. It is shown how the single-task distribution and the number of task repetitions can be used to determine the minimum differences in task repetitions necessary to distinguish for epidemiological purposes between worker groups on the basis of cumulative exposure.
