Abstract |
A technique and the required instrumentation for routine mapping of magnetic lung contamination in vivo is described. The apparatus consists of a patient chair which moves during the mapping between 2 transducers; 2 magnetising coils producing a magnetic field to magnetise the lung contaminants; a minicomputer for control, calculations, and recording. Measurements of lung contamination in mild steel and stainless steel welders are reported. Resolution is 0.1nT, corresponding to a sensitivity better than 1mg of magnetic contaminants in the form of iron oxides. The magnetic properties of welding fumes produced in these welding processes are reported. |
