Magnetic Fields in the Dental Surgery

U radu su mjerena magnetna polja u zubnim ordinacijama uz pomoć posebno konstruirane naprave s Hallovim pokusom. Napravom su se mjerili srednji kvadrati udaljenosti magnetnoga polja u ovisnosti o položaju pojedinog stomatološkog uređaja u prostoru. Dobiveni su podatci analizirani metodom jednostavne statističke regresije. Istraživanja su pokazala da je jakost magnetnoga polja većine ispitivanih uređaja neopasna za čovjeka. Ona se smanjuje što je udaljenost veća od izvora zračenja. Stariji uređaji zrače jače od uređaja novije proizvodnje.In this study magnetic fields in dental surgeries were measured by means of a specially constructed device with a Hall\u27s probe. The purpose was to measure the mean square distance of the magnetic field in relation to the position of dental apparatus in the area. The dana obtained were analysed by the method of simple statistical regression. The study showed that the force of the magnetic field of the majority of the examined apparatus is harmless to man. The force decreases with increasing distance from the source of radiation. Older apparatus radiates stronger than newer products
