It is sometimes said that there is no research evidence that microwaves have biological effects apart from heating (thermal) effects. There are, however, experts who point to a great deal of evidence.

Professor Henry Lai, a biologist at Washington University who has carried out studies on mobile phones, is reported saying, “I think it is irresponsible to just set standards using a thermal standard. If you set it just based on a thermal effect you are neglecting a large amount of data.” 47

Dr. Neil Cherry of Lincoln University, New Zealand, wrote in 1999, “there is a wealth of laboratory evidence of cellular and animal changes at extremely low exposure levels to RF/MW [radiofrequency / microwave] radiation, accompanied by a massive body of epidemiological research which shows adverse health effects in human beings down to extremely low life-time mean exposure levels for chronic exposures.” 48

Professor Olle Johansson, of the Karolinska Institute in Sweden, has expressed deep concern about the spread of wi-fi, saying that there are “thousands” of articles in the scientific literature showing “adverse health effects.” “Do we not know enough already to say, ‘Stop!’?” he asks. 49
