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.
摘要
针对一项涉及从医院消毒器转移材料的任务，估算了环氧乙烷暴露的统计分布。暴露数据符合正态分布或对数正态分布。文中展示了如何利用单任务分布和任务重复次数来确定为基于累积暴露在流行病学层面区分工人群体所需的任务重复次数的最小差异。
