Job-exposure matrix - Wikipedia
A job-exposure matrix (JEM) is a tool used to assess exposure to potential health hazards in occupational epidemiological studies . Essentially, a JEM comprises a list of levels of exposure to a variety of harmful (or potentially harmful) agents for selected occupational titles.

Job Exposure Matrix
The noise Job Exposure Matrix (JEM) consists of nearly one million occupational noise exposure measurements across 275 industries. The JEM was constructed by collecting noise exposure measurements from OSHA, MSHA, private industry, and published literature between 1963-2015. Our JEM web App can be used to filter, visualize, and download the noise ...

Exposure Assessment Using Job Exposure Matrices - National ...
Job Exposure Matrices (JEMs) are an efficient way to assign exposure estimates in population-based studies and may be the only exposure assessment option when only job and industry are available for study participants. DCEG investigators develop methods to improve JEMs by incorporating databases of exposure measurements to calibrate JEMs across ...

Job exposure matrix (JEM) is a term already used to describe a method for estimating average, peak and total dose exposure metrics to individual cases and controls in epidemiology studies. Applying the same name to a different concept and metric can only create confusion.

Beyond the job exposure matrix (JEM): the task exposure ...
The job exposure matrix (JEM) has been employed to assign cumulative exposure to workers in many epidemiological studies. In these studies, where quantitative data are available, all workers with the same job title and duration are usually assigned similar cumulative exposures, expressed in mgm(-3)xyears.

Development of a job-task-exposure matrix to assess ...
Assessment of exposure by a job-exposure matrix (JEM) is less prone to differential misclassification bias than self-report and is a low-cost exposure assessment method, but attributes the same exposure to all the workers in a given job,10, 11 and thus does not take into account the variability of exposure between workers within the same occupation.12 Occupational exposure may be heterogeneous for a given occupation according to the tasks performed.
