title: [TECHNICAL ASPECTS OF EXPOSURE TO MAGNETIC FIELDS OF EXTREMELY LOW FREQUENCIES (ELF) IN BIOMEDICAL RESEARCH].
abstract: BACKGROUND
  Experiments on the electromagnetic field influence on organisms are an important part of biophysical studies. It is an interdisciplinary research spanning biology and medicine with the engineering in generation and measurement of electromagnetic fields. The aim of the study consists the analysis of parameters estimations and measurements of extremely low frequency magnetic field (ELF MF) as well as exposure systems parameters in biomedical research.
  
  
  METHODS
  Experiments were performed on 2 most popular low magnetic field exposure systems: the solenoid and Helmholtz coils. A theoretical analysis and a measurement verification of the magnetic field distribution inside the systems were carried out to evaluate the homogeneity of the magnetic field. Additional factors, vibrations and temperature changes, affecting the assessment of the biological effects of magnetic field exposure were also examined.
  
  
  RESULTS
  Based on the study results, a comparative analysis of solenoids and Helmholtz coils as the magnetic field exposure systems was presented. Proposals for the description of magnetic field exposure were also formulated.
  
  
  CONCLUSIONS
  The authors emphasize the importance of a conscious choice of exposure conditions and their explicit description. These are fundamental requirements for both the reproduction of experiniental conditions and the verification of results.
