There is a more or less magnetic field in the machines used in homes, businesses, heavy industry facilities, factories, hospitals, offices and similar facilities, wherever there are electronic devices. Being in electromagnetic fields has dangerous consequences for human health. Safety of working environments is ensured by making electromagnetic field measurements.

The magnetic field occurs wherever there is an electric current. The higher the electric current, the higher the magnetic field. The electromagnetic field is a combination of electric and magnetic fields. The electric wave and the magnetic wave are exchanged together at the speed of light. Electromagnetic fields are defined by their frequencies and wavelengths. Frequency is the number of vibrations of a wave per second. Wave length is the distance traveled by the wave during vibration. Accordingly, if the frequency is high, the wavelength is short and the energy emitted in the magnetic field is high.

The short-term effects of the magnetic field on the human body are: stress, narrowing of the field of vision, tinnitus, feeling of fatigue, impaired concentration, headaches, transient hearing impairment and dizziness. In the long term, the magnetic field has the following effects on the human body: genetic impairment, death of brain cells, brain tumor, white blood cell cancer, heart disease, memory impairment, permanent hearing impairment, miscarriage, deterioration of blood cells.

Therefore, in terms of employee health and safety, it is necessary to measure the intensity of the electromagnetic field to which the employees are exposed and to take necessary measures according to the results.

Electromagnetic field measurements are also performed in accredited laboratories within the framework of indoor measurements. During these measurements, laboratories must comply with the standards of TS EN ISO / IEC 17025 General Requirements for the Competence of the Testing and Calibration Laboratories.

Laboratories also operate in accordance with current regulations and standards published by domestic and foreign organizations.
