The Effects of Electromagnetic Radiation on Human Body Fluids by Simulation Using Replacement Fluids at a Frequency of 900 Mhz

In line with technological developments, cell phones are not only used as a means of communication, but are also used for other activities. However, there is an indirect negative impact caused by the electromagnetic field radiation from this device. As well as disrupting the work system in the human body, including changes in heat energy in the tissues of the human body. Research on the effect of electromagnetic radiation on human body fluids has been carried out with simulations using replacement fluids at a frequency of 900 Mhz. Signal generators are used to simulate the emissivity of a cell phone with a transmit power of more than 3.4 times or 5.34 dB of the power emitted by a cell phone. The results of measurements and calculations in the study showed no significant effect on temperature increases or changes in body fluid color. The result of the calculation of the SAR (Specific Absorption Rate) value of the maximum emissivity signal produced is 109.46 dBµV - 0.3 V/m, for the conductivity and density of body fluids is 7.46 kg/m3, and shows that it is still below the threshold. the radiation limit permitted by the FCC is 1.6 W/kg, and ICNIRP 2.0 W/kg. It should be noted that the measurement results obtained are the results of measurements including environmental conditions where there is still wave interference from other sources (noise), as well as a relatively short measurement time.
