ELF Survey Meter and its Application in Investigation of Electric and Magnetic Safety for Uranium Mines

In this paper it has been presented the ELF Survey Meter and its application for investigation of presence of electric and magnetic fields strength in uranium conversion mines, especially to investigate the effect of electric and magnetic sources on the operation of electrical controllers like PLC instruments, electrical drivers and actuators which are sensitive to presence of electrical and magnetic fields and also the effect of high voltage power lines on human body. It shows the importance of ELF survey meter using in most stages of the processes and related controllers in uranium mines to work precisely, not affected by electric and magnetic noises and guarantee the safety of person who works near the electrical sources or power lines.
