We have relied upon X-rays for the diagnosis of such diposits, even though minutes particles lodged in the lungs for long periods are almost impossible to dectect with X-rays. When such condition become detectable with X-rays, it is already too late to transfer the patient within the company, after the case, when, it's essential that we know figure that measure the total quantity and distribution of materials accumulated in the lungs by using the magnetic characteristic of particles. The measurements are summarized of the amount of magnetic dust in the lungs asbestos foundry workers, welders, miners, asbestos manufactures, coal, urban dwellers in general etc.., method adds a magnetic field of strong direct current from the outside to particles are accumulated in the lungs. It magunetizes the particles and after taking out the out side magnetic field, these particles occur a slight magnetic field out side as a remaining magnetism. It's possible to get the quantity and distribution of particles are accumulated in the lung by measuring this magnetic field on the surface of the boody. The device which we reported already was a big instrument, and therefore movement of it was not easy. This reportis about the sectional instrument can be moved to easily.
