Abstract
The measurement of the remanent magnetic field of the human lungs contains a lot of information about the behavior of magnetic material in the lungs. To study working place situations of people who are exposed to magnetic dust, the amount of deposited material in the lungs can be detected. It was found that there were many dusts containing magnetic contaminants: welding fumes, coal-mine dust, asbestos, grinding dusts (Cohen et. al., 1981, Kalliomaki et. al., 1978, Freedman et. al., 1980). The amounts in the lungs of the workers were found to be several hundred up to thousand milligrams. After voluntary inhalation of magnetic particles (Fe3O4, magnetite) the long time clearance mechanism from the alveolar region of the lung can be studied (Cohen, 1973). Halftimes for this clearance were found to be near 100 days, so a radioactive method is not suitable for human studies of long time clearance.
