Sažetak
The principal objective was to measure the magnetic fields occuring in dentists work place at simultaneous subtraction of direct ground component of magnetic field. The research instrument used to measure the power of magnetic field was of our own design. It measures the magnetic field by the Hall sensor that is powered with 5 to 10 V and is integrated in chip together with pre-amplifier. Its tasks was to measuremean square values of the field ( RMS ) dependent on the position in space. The obtain was analysed by simple statistical regression method and for that purpose the data were transformed from the exponential model into the linear one that is appropriate for regression analysis that enables the calculation of magnetic field values at any point in the space. Deviations are relatively small for which reason the regression model describes the obtained data in satisfactory manner.The following conclusion is made on the basis of our stady results and their statistical analysis: The power of magnetic field decreases with increasing distance from the source ; Magnetic field spreads through space in ISOTROPIC manner ; The investigated instruments produce negligible effects on dental staff and their patients ; The newly designed and produced instruments act on their environment by smaller magnetic fields ; The sensitivity of measurement instruments was 0.0001uT ; the majority of instruments produce magnezicfield radiation higher than 40G.
