... Evidence suggests that job design and task requirements can produce jo~related physical symptoms and stress. Thus it is possible that differences in reported symptoms between VDT workers and non-VDT workers might be more directly related to characteristics of the work situation -- i.e., the way in which

... Temporary changes in measures of visual function reported to occur following VDT work appear to be similar to those observed after performance of near-visual tasks in non-VDT jobs. Most features of VDT work tasks that may contribute to discomfort or visual difficulty are also found in various jobs not involving VDTs; however, poorly designed VDTs, workstations, and work tasks, often produce a particularly problematic concatenation of adverse features.

... occupational radiation exposure standards and are generally much lower than the ambient radiation emitted by natural and human-made sources to which people are continuously exposed. We have not attempted to evaluate the adequacy of existing standards, but our review of the scientific literature on biological effects of radiation indicates that the levels of radiation emitted by VDTs under conditions of normal operation and under conditions of malfunction or aging of the VDT are highly unlikely to be hazardous.

... Research on psychosocial parameters that affect all jobs, such as workload, task complexity, and social support, would seem to offer more potential benefit than research on psychosocial variables specific to VDT work. We emphasize, however, that application of existing knowledge in designing and using VDTs should be given high priority.
