The proportion of global mobile phone users has exceeded 60%. Meanwhile, the implantation rate of cardiac pacemakers is increasing year by year. As a result, cardiac pacemakers will inevitably be exposed to the electromagnetic environment generated by mobile phone antennas. This paper aims to evaluate the bioelectromagnetic effects from antennas radiation on the patients wearing pacemakers to determine their potential role in human health. This study uses the COMSOL Multiphysics software to analyze the E, H, specific absorption rate (SAR) distribution, and temperature-change patterns of the patient’s chest and heart over 30 min. The results show that the maximum E and H of the chest are 9.3 V/m and 0.06 A/m, and the maximum E and H of the heart are 2.67 V/m and 0.036 A/m. The SARmax value of the chest is 0.00365 W/kg, the SARmax value of the heart is 0.00212 W/kg, the maximum temperature rise of the chest is 0.00005 ℃, and the maximum temperature rise of the heart is 0.000037 ℃. The results show that the radiation level are below the limit value of ICNIRP, and will not endanger the health of people with pacemakers.

摘要

The proportion of global mobile phone users has exceeded 60%. Meanwhile, the implantation rate of cardiac pacemakers is increasing year by year. As a result, cardiac pacemakers will inevitably be exposed to the electromagnetic environment generated by mobile phone antennas. This paper aims to evaluate the bioelectromagnetic effects from antennas radiation on the patients wearing pacemakers to determine their potential role in human health. This study uses the COMSOL Multiphysics software to analyze the E, H, specific absorption rate (SAR) distribution, and temperature-change patterns of the patient’s chest and heart over 30 min. The results show that the maximum E and H of the chest are 9.3 V/m and 0.06 A/m, and the maximum E and H of the heart are 2.67 V/m and 0.036 A/m. The SARmax value of the chest is 0.00365 W/kg, the SARmax value of the heart is 0.00212 W/kg, the maximum temperature rise of the chest is 0.00005 ℃, and the maximum temperature rise of the heart is 0.000037 ℃. The results show that the radiation level are below the limit value of ICNIRP, and will not endanger the health of people with pacemakers.
