Abstract:

The aim of this research was to investigate the electromagnetic fields in the modern office environment. Both low frequency and the high frequency electromagnetic fields were studied. The sources of elevated electromagnetic fields and the conditions under which they occur were identified. Measurements were performed by following a 14-point human body model, which characterizes the overall exposure of the sitting person.

The measurements analysis revealed the most typical sources of exposure to be loosely spread power wires and extension cables, but also power cables close to the worker’s body on the floor or beneath the table. Standard office devices were also rising the exposure levels when situated in close proximity to the worker.

Key words:

electromagnetic fields, extremely low frequency, occupational exposure, office, radiofrequency
