      <subfield code="a">It is generally assumed that workers employed in the same job at a given location are uniformly exposed, i.e., that they have the same long-term mean exposure. This assumption has led to observational schemes for classifying workers into homogeneous exposure groups (HEGs), based on job title, location and otheridentifiable features of the work environment. This paper presents results from analysis of 183 HEGs in which it was possible to determine the between-worker component of variance in exposure</subfield>
