View Original AbstractHuman skin cells showed no stress response to 48-hour cell phone radiation exposure at maximum safety limits, unlike clear damage from heat and UV controls.
Plain English Summary
French researchers exposed human skin cells to GSM cell phone signals at the maximum allowed exposure level for 48 hours, looking for signs of cellular stress like those caused by heat or UV radiation. They found no evidence that the radiofrequency radiation caused stress responses or cell death, unlike the positive control treatments that clearly damaged cells. This suggests that cell phone radiation at current safety limits may not directly harm skin cells in laboratory conditions.
Study Details
The evolution of mobile phone technology is toward an increase of the carrier frequency up to 2.45 GHz. Absorption of radiofrequency (RF) radiation becomes more superficial as the frequency increases. This increasingly superficial absorption of RF radiation by the skin, which is the first organ exposed to RF radiation, may lead to stress responses in skin cells. We thus investigated the expression of three heat-shock proteins (HSP70, HSC70, HSP27) using immunohistochemistry and induction of apoptosis by flow cytometry on human primary keratinocytes and fibroblasts.
A well-characterized exposure system, SXC 1800, built by the IT'IS foundation was used at 1800 MHz, ...
The results showed no effect of a 48-h GSM-1800 exposure at 2 W/kg on either keratinocytes or fibrob...
We thus conclude that the GSM-1800 signal does not act as a stress factor on human primary skin cells in vitro.
