Bioelectromagnetism laboratory - Case study

The paper presents a case study concerning the emplacement of a laboratory dedicated to bioelectromagnetism researches. It also shows the complex structure of the laboratory and related facilities. Laboratory research is designed in two frequency ranges of magnetic and electromagnetic fields: (0-500) Hz frequency range, explored by biomagnetometry and very low energy electromagnetic radiation corresponding to thermal radiation in the microwave range.The installation components consisting of a nonferromagnetic shielded room, lined inside by microwave absorbent material with pyramidal geometry and a complex triaxial coils system to control the ambient magnetic fields: geomagnetic components and those due natural variations, the fields produced by human activity - the movement of masses of metal, vehicles, magnetic field of 50 Hz etc. The installation permits the detection of magnetic activity of the heart (magnetocardiogram - MCG) and the measurement of the internal temperature of living structures using the microwave radiometry. This is an application for non-invasive early breast cancer detection. Performances of the installation are presented.
