Conflicting reports about the health risks of mobile phones appeared in the late 1990s

  • £7.4 million has now been invested in scientific research to investigate the effects of mobile phones
  • 2004: there are more than 40 million mobile phones in the UK and over 30,000 base stations
  • In 2000, the Stewart Report found no known health problems caused by mobile phones, but advised caution especially among the young, until more research was carried out. A further report in 2004 backed this up
  • Given the immense numbers of mobile users, even small adverse effects on health could have major public health implications
