Study type: Medical/biological study (experimental study)

ELF non ionizing radiation changes the distribution of the inner chemical functional groups in human epithelial cell (HaCaT) culture med./bio.

Published in: Electromagn Biol Med 2006; 25 (4): 281-289

Aim of study (acc. to author)

This in vitro study was performed to investigate changes in morphology and phospholipid/protein distribution of sinusoidal extremely low frequency electromagnetic field exposed human keratinocytes.

Background/further details

The temperature was continuously measured and maintained at the range of 37 +/- 0.3°C.
