Abstract

An electron microscopical study of snail neurons was undertaken to verify whether any ultrastructural alterations accompany microwave-induced electrophysiological changes observed in these neurons. Subesophageal ganglia from Helix aspersa snails were exposed to 2450 MHz microwave radiation in vitro at SAR 12.9 mW/g for 60 minutes. It was found that exposure at 21 degrees C causes minor changes in Golgi complexes and slight swelling of the endoplasmic reticulum.

Main findings

Subesophageal ganglia from Helix aspersa snails exposed in vitro to 2450 MHz microwave radiation (SAR 12.9 mW/g) for 60 minutes at 21°C showed minor changes in Golgi complexes and slight swelling of the endoplasmic reticulum.

Outcomes measured

  • Neuronal ultrastructure (electron microscopy)
  • Golgi complex changes
  • Endoplasmic reticulum swelling

Limitations

  • Sample size not reported in abstract
  • In vitro exposure of isolated ganglia; generalizability to whole organisms/humans unclear
  • Only ultrastructural endpoints described; no quantitative effect sizes reported in abstract
