SOME ASPECTS OF HOME ECOLOGY: MEASURING THE LEVEL OF EMF FROM HOUSEHOLD APPLIANCESKira M. TrushinaAbstract The results of domestic and foreign studies clearly indicate the high biological activity of EMF. In a residential environment, a person is exposed to electromagnetic fields from a variety of sources. The purpose of this work was to determine the level of EMF near various household appliances and develop appropriate safety recommendations. To achieve the goal, the following tasks were set: to measure the levels of electric field strength, the level of magnetic induction, to determine the distances to the devices at which the threshold values of EMF are not exceeded. Measurements of the intensity of electric and magnetic fields of industrial frequency 50 Hz were carried out from sources located in residential premises; a total of 26 EMI sources were examined. almost all household appliances are EMF sources, and some devices both in operation and in standby mode exceed the maximum permissible values of electric field strength and magnetic induction, indicated in GOST R 54148-2010 and San PiN 2.1.2.1002-00 (E = 25 V/m, V = 250 nT). The greatest concern is the proximity of the human body with such devices as a slow cooker, a vacuum cleaner, a radio receiver and a hair dryer. For example, the highest values of the electric field strength were noted for a bread maker, and magnetic induction for a vacuum cleaner. Based on the data obtained, it can be concluded that for the safe use of household appliances, it is desirable to be located at least 50 cm away from them. Devices that are not in use at the current time must be disconnected from the electrical network. |
