| Resumen |
The assessment of the electromagnetic field exposure of welders is of great importance, especially in shielded-arc welding which uses relatively strong electric currents of up to several hundred amperes. This study measured the magnetic field exposure level of welders during their work. A 3-axis Hall magnetometer was attached to the subjects' wrists in order to place the sensor probe as close as possible to the magnetic source. Data was acquired every 5s. The maximum exposed field was 0.35-3.35 mT and the average value per day was 0.04-0.12 mT. Finite element analyses of human hand tissue were conducted for electromagnetic field dosimetry. Magnetic fields associated with grinders, air hammers and electromagnetic drills were also measured, but were found to be much lower than those generated during the welding process. |
