They also report an \"abnormal jump\" for breast fat (classified as epithelial) being highly affected in their simulation. The paper concludes that 5G could increase EMF exposure due to stronger beam directionality and smaller cell size.",

  "summary": "This conference paper reports MATLAB simulations estimating SAR and power density across more than 40 tissue types at stated frequencies from 20 to 100 GHz. The authors report that nerve tissues had the highest calculated exposure among the tissue groups, while muscle tissues were the least affected. They conclude that 5G could increase EMF exposure due to beam directionality and smaller cell size, but the abstract does not report health outcomes or measured human data.",
  "key_points": [
    "The work is a computational simulation using MATLAB rather than an experimental or epidemiological study.",
    "SAR and power density are calculated for >40 tissue types across stated 20–100 GHz frequencies.",
    "Nerve tissues are reported as the most affected tissue group in the simulation results.",
    "Muscle tissues are reported as the least affected tissue group.",
    "Connective and epithelial tissues are reported to be affected in a similar range.",
    "Breast fat is noted as an outlier with high reported effect in the simulation.",
    "The paper frames 5G as potentially increasing exposure due to beam directionality and smaller cell size."
