Magnetopneumography is a non-invasive method for measuring of the powdered ferromagnetic particles of retained dust which have been accumulated for long periods of time in the respiratory tract due to exposure of the contaminated occupational environment. The method consists of exposing the chest to a uniform DC magnetic field and subsequently by measuring the remanent magnetic induction of the ferromagnetic particles by scanning the subject's chest under a stationary probe. For magnetopneumography the SQUID magnetometric system with the high sensitivity of 2.10-14 T Hz-1/2 at white noise range is used. This system enables to identify the mass concentration of the powdered ferromagnetic particles in some biological structures with the resolution of the order of micrograms per cm3. At present, the SQUID system is used for monitoring the contamination of the respiratory tract and the lungs for the diagnosis of the pneumoconiosis of steel welders.


The system is also adaptable for biomagnetic measurements of the ferromagnetic particles deposition in other organs of the human body, or for nondestructive screening the ferromagnetic particles in various dia- and paramagnetic materials.


Health service: Diagnosis of the diseases caused especially by contamnation of the heterogeneous substances in the organism. Long-time monitoring of the therapeutics and the prophylactics of the occupational diseases. In the technical practice: The non-contact detection of the ferromagnetic materials with very low mass concentration.


The complete stationary laboratory system with the original tested measuring method. Magnetopneumography was applied to the group of steel welders.


Realization of the complex measurements on the basis of contract with the customer or with declared cooperation in the development of new applications of the measuring system.
