Original sentence: " It is important to note that the sham was also emitting RF radiation at a lower level, and that the reaction of participants to the sham exposure may also be related to EMFs.A common position presented regarding these effects is that, since they are not well understood, a precautionary principle approach would suggest minimizing exposure whenever possible.Because the extent of Non-thermal effects is not fully established, they may be beneficial or harmful.However, it should be recognized that the claims of biological hazards from low-energy electromagnetic radios (e.However, the 2006 Rubin study concluded that "No evidence was found to indicate that people with self reported sensitivity to mobile phone signals are able to detect such signals or that they react to them with increased symptom severity.It does not seem to be a congenital condition and theories have been put forth that some form of external trigger such as previous chemical exposure may bring about this electrical sensitivity (ES).Some studies have even suggested that a small percentage of the population may be electromagnetically sensitive and can physically react to very low level fields even in double-blind experiments, such as participants withdrawing from background levels in the 2006 Rubin study.The theoretical mechanism of action of non-thermal electromagnetic fields is not fully understood, but there are some established biological effects for ELF.There is also a body of evidence which supports the existence of complex biological effects of weaker non-thermal electromagnetic fields (see Bioelectromagnetics), including weak ELF magnetic fields and modulated RF and microwave fields.from mobile phones) are considered controversial
Edited sentence: However, over 30 provocation studies have found no truth in the claims that some people can detect electromagnetic fields, and the scientific consensus is that there are no non-thermal biological effects of low powered devices.The 2006 Rubin study concluded that "No evidence was found to indicate that people with self reported sensitivity to mobile phone signals are able to detect such signals or that they react to them with increased symptom severity.There is also a body of anecdotal evidence which supports the existence of complex biological effects of weaker non-thermal electromagnetic fields, including weak ELF magnetic fields and modulated RF and microwave fields
