The interactions of electromagnetic waves emitted by radiator with the biological tissues are studied. The photon of electromagnetic waves (EMW) are scattered by the different tissues inside the body and created the phonon. In this process, energy is transferred from one tissue to another and in every step; energy is absorbed by the tissues. In this manuscript, the penetrated electric field of selective tissues of human body and absorption of energy has been calculated and the calculated electric field and specific absorption rate (SAR) are compared with the International permissible limit given by some International Commission of Non-ionizing Radiation Protection (ICNIRP) and World Health Organization (WHO) etc. It is found that penetrated electric field inside the tissues represents that frequency 30-50 kHz are harmful for some tissues while specific absorption rate (SAR) represents that (30-70) kHz are harmful for cerebella spinal fluid, gall bladder bile, and body fluid etc. of the human beings. After analysis, it is concluded that people should keep away from the radiator.
