Magnetic field exposure in a nondestructive testing operation.
This exposure assessment measured peak magnetic fields during magnetic particle inspection, a nondestructive testing method that uses electromagnetism. Ninety-five peak measurements taken while inspecting 8 turbine engine shafts ranged from <0.1 to 29.27 mT. The authors note these values are among the highest reported in occupational settings and recommend further work to characterize exposures by current frequency and device type.
Key points
- Magnetic particle inspection is a nondestructive testing method that can expose operators to magnetic fields.
- Peak magnetic field measurements were collected during inspection of 8 turbine engine shafts at an overhaul and repair center.
- A total of 95 peak measurements ranged from <0.1 to 29.27 mT.
- The authors describe the measured exposures as among the highest reported in occupational settings.
- The abstract calls for additional exposure characterization, including separating field magnitude by current frequency.
- The abstract also suggests examining how exposure varies across different magnetic particle inspection devices.
