Analyzing the SAR in Human Head Tissues under Different Exposure Scenarios

This paper deals with the assessment of induced specific absorption rate (SAR) in various human models under different exposure scenarios, including both laboratory measurements and simulations. Firstly, SAR values were measured a standardized using phantom for two radiofrequency electromagnetic field (RF-EMF) sources at 900 MHz 1800 MHz. These served as reference calculations conducted on anthropomorphic mannequin (SAM) computer simulation technology (CST) program, thus enabling determination antenna location excitation signal levels further evaluation. Subsequently, simulations carried out CST to evaluate average head tissues such brain, muscles, fat. Realistic computational also used alongside SAM explore influence gender, age, tissue type SAR. Various power representing low, moderate, high RF-EMF applied compare against basic restrictions levels. The results indicate significantly higher calculated compared ratio highest is approximately 1.70 baby, 2.59 child, 2.84 adult female male. While fat, muscle, are comparable brain’s value stands from other tissues. In contrast difference between more pronounced lowest obtained brain all models, while has value. maximum change be 4.44 male reveal that, although below general public local exposure, some exceeded International Commission Non-Ionizing Radiation Protection’s restriction certain levels, particularly analysis derived this study significant understanding impact wireless technologies health, establishing safety standards, guiding advancement, conducting risk assessments, increasing awareness.
