Reported exposure parameters did not exceed ICNIRP limits, but in some cases exceeded limits referenced from the BioInitiative Report.",

  "summary": "This paper compiles findings from 13 publications over 14 years from one institution, primarily focused on RF emissions from mobile phones (GSM900/GSM1800). It reports associations with changes in heart rate variability and autonomic nervous system activity, and mentions symptoms such as headaches, concentration loss, and burning sensations near the ear. Reported exposure parameters were within ICNIRP limits, though some measurements reportedly exceeded limits cited in the BioInitiative Report.",
