In the current scenario the radiofrequency radiation (RFR) emitted from wireless equipment viz. mobile phone towers, mobile phones, computers, laptops, microwave ovens, high voltage electric lines etc. has been increased continuously and expose the living beings. The human cells are affected by electromagnetic fields (EMF) and with the development of the fifth generation (5G) of mobile communication technologies and frequency are far increasing; the human skin becomes the first main biological tissue of the human body. In this paper Author’s evaluated SAR for skeletal muscles in human body at 2.4 GHz Radiofrequency (RF) and discuss its harmful effects.Those peoples are living nearby mobile phones towersare exposed directly by EMRand regarding their health issues due to Non-ionizing electromagnetic radiation, The Specific Absorption Rate (SAR) within human body skeletal muscle is calculated through mathematical model and results were compare with standard permitted values of SAR given by many National and International agencies like International Commission non- ionizing radiation Committee (ICNIRC), National Council on Radiation Protection and Measurement (NCRP), World Health Organization (WHO), Federal Communication Commission (FCC) and Department of Telecommunications (DOT) etc.
