Evaluation of Magnetic Field Exposure to Office Employees from an Electrical Transformer [open pdf - 4MB]
"NIOSH [National Institute for Occupational Safety and Health] investigators evaluated exposures to magnetic fields in the timekeeping office of a correctional institution. All personal and area magnetic field measurements were well below applicable OELs [Occupational exposure limit]. Exposures can be further lowered by reducing the time spent near magnetic field sources and increasing the distance between these sources and employees."
