非热效应In December 2004 a pan-European study showed compelling evidence of DNA damage of cells when exposed between 0.3 to 2 watts/kg. This overlaps with the level of radiation typically emitted by digital cell phones of around 0.2 to 1 watt/kg. There were indications, but not rigorous evidence of other cell changes, including damage to chromosomes, alterations in the activity of certain genes and a boosted rate of cell division. [2] The results of this study run contrary to many similar studies that were conducted before and showed no increase in DNA damage. [3]The communications protocols used by mobile phones often result in low-frequency pulsing of the carrier signal. These low frequencies are similar to those that exist in the electrical oscillations of the human body, specifically the alpha and delta brain waves. Non-linear interactions could theoretically result when resonances are created when the brain is subjected to mobile phone radiation, in a manner similar to that observed when light strobing induces photosensitive epilepsy in susceptible individuals. No experimental results have indicated this theoretical possibility, however. These and other non-thermal effects are summarized in (Hyland, 2000). |
