This is copied from an open letter of UK medical doctors to take immediate action against the use of technology near children and pregnant women: We wish to highlight our concern over the safety of exposure to microwave radiation from wireless technology, particularly for vulnerable groups like children, pregnant women, the elderly and those with compromised health. There is growing concern that chronic (long-term) exposure to radiofrequency/microwave radiation from wireless technologies causes damage, particularly genetic damage, cognitive damage, cancer and decreased fertility.  There is now substantial evidence of a link between mobile phone use and brain cancer.  This was recognised by the International Agency for Research on Cancer (IARC)’s 30-strong panel of scientists, which in 2011 classed radiofrequency radiation as “possibly carcinogenic”.
Additionally, doctors are encountering a significant and growing number of people presenting with a range of acute (short-term) symptoms from wireless radiation, including headaches, palpitations, rashes, fatigue, sleep disturbance, allergies and memory and concentration problems. International medical agencies have recognised the evidence of harm (see appended list) but these rulings may take many years to be reflected in public health policy.
