The Health Protection Agency ran a comprehensive review of the use of mobile phone technologies and other wireless devices, such as WiFi, as well as television and radio transmitters.
The HPA's independent Advisory Group on Non-ionising Radiation (AGNIR) concluded that there is "no convincing evidence that mobile phone technologies cause adverse effects on human health".
According to the report, there is also no indication that RF (radio frequency) field exposure below internationally agreed guideline levels (as applied in the UK) can cause health effects in adults or children.
The researchers further noted that a large number of studies have been published to date showing that the use of mobile phones does not cause brain tumours or any other type of cancer.
However, the report noted that mobile phone technology has only been in widespread public use for a relatively short period of time, and there is little information on the risks beyond a 15-year period.
Therefore, the research team said that it is important to continue to monitor the evidence, including the national brain tumour trends, to see if there are future signs of risk.
They added that there is "no substantial evidence" that long-term RF field exposure has adverse health effects, such as cardiovascular morbidity and reproductive function, but noted that research remains limited in the area.
Professor Anthony Swerdlow, the chairman of the group, said: "There are still limitations to the published research that preclude a definitive judgment, but the evidence overall has not demonstrated any adverse effects on human health from exposure to radio frequency fields below internationally accepted guideline levels."
Dr John Cooper, the director of the HPA's Centre for Radiation, Chemical and Environmental Hazards, added: "There has been considerable new scientific evidence published since the last AGNIR report in 2003, and this report further consolidates the evidence base on which the HPA issues its advice.
"The HPA's position on mobile phone technologies is in line with the AGNIR's findings. There is still no convincing scientific evidence that RF field exposures from mobile phones and other radio technologies affect human health at exposure levels below internationally agreed guidelines.
"However, as this is a relatively new technology, the HPA will continue to advise a precautionary approach and keep the science under close review."
The HPA also recommends that excessive use of mobile phones by children should be "discouraged", and the Specific Energy Absorption Rates (SAR) of mobile phones should be "clearly marked in the phone sales literature".
