Assessment of occupational exposures in case-control studies has traditionally been limited because of the lack of information on the variability of exposures across and within jobs. NCI has developed special questionnaires with modules designed to obtain detailed exposure-oriented information for over 40 specific jobs and over 10 specific industries. These modules include questions on tasks, work practices, chemicals, equipment, engineering controls, personal protective equipment and indirect exposures specific to those jobs and industries.
Examples of jobs and industries for which questionnaires have been developed include:
