The measurements of magnetic field were performed with the aid of TRIAXIAL ELF Magnetic Field Meter. The level of magnetic field were found in the range 1 to 197 with mean value of 51.6 ± 44.2 mG.The survey of magnetic field measurements revealed that the level of radiation dose found to be far below than the international standard dose limit for the public exposure set by the International Commission on Non-Ionizing Radiation Protection ICNIRP 830 mG.
