EMF Exposure and SAR Analysis in the Cow Tissues

There is a tremendous increase in use of RF electronics in veterinary for tracking and health check of animals. The mechanisms of magnetic and electromagnetic effects in biological systems are known, effect of electromagnetics in biological tissues are generally studied in human tissues in the literature, and the mechanism was convincingly established for enzymatic adenosine triphosphate (ATP) and desoxynucleic acid (DNA) synthesis. In this study, the SAR effect of pH boluses used to monitor the rumen pH value of animals has been tried to be revealed. For this purpose, active RFID tags operating at 434 MHz have been placed in the rumen zone by adding a pH sensor and the rumen pH values have been monitored dynamically for two months. The SAR value generated by active RFID tag antennas with 1 mW output power has been modeled with the help of a simulation program. The resulting SAR effect appears to be well below the legal limit.
