  "summary": "This plant study exposed dry chickpea seeds to RF sources (900 MHz GSM phone and 3.31 GHz laptop) for 24 or 48 hours and assessed genotoxicity using a chromosomal aberration assay. The authors report reduced germination, decreased mitotic index, increased abnormality index, and nuclear/cellular abnormalities including micronuclei. They interpret fragmentation and “ghost cells” after 48 hours as suggesting possible carcinogenic potential and recommend limiting unnecessary device use.",
  "key_points": [
    "RF exposure was applied using a GSM cell phone (900 MHz) and a laptop (3.31 GHz) for 24 and 48 hours.",
    "Untreated seeds served as negative controls and gamma rays (250 Gray) as a positive control.",
    "All RF treatments reportedly inhibited seed germination compared with controls, with the 48-hour laptop exposure described as most negative.",
    "Mitotic index decreased and abnormality index increased with longer exposure duration and higher frequency.",
    "Chromosomal aberrations such as micronuclei, bi-nuclei, multi-nuclei, and scattered nuclei were reported after RF exposure.",
    "Cell and nuclear membrane damage, fragmentation, and “ghost cells” were reported mainly at 48-hour exposures.",
    "The authors conclude RF was genotoxic in this assay and suggest possible carcinogenicity based on observed cellular changes."
