QUANTITATIVE ANALYSIS OF POWDERED FERROMAGNETIC MATERIALS CONTENT IN MAGNETOPNEUMOGRAPHY

Boháková Fatima, Šimáček Ivan

Abstract

Possibilities for quantifying the ferromagnetic particle contamination in human lungs with help of a rf SQUID system were studied. A tool for the analysis of the quantification of the measured data was developed. Conditions for the calculation of the particle concentration in human lungs from the measured remanent magnetic induction were established. The theoretical calculations were verified by measuring on physical lung models. The illustration of the method and a rough estimation of the concentration were carried out on an arc welder, with evidently contaminated lungs. The work also contains a discussion on problems associated with measuring the remanent magnetic induction in living organisms.
