US mobile phone makers must show radiation level of radiation

Mobile phone makers in the United States have been ordered to disclose consumer information on radiation emissions, from next month.

Mobile phone makers in the United States have been ordered to disclose consumer information on radiation emissions, from next month.

The order, from the Cellular Telecommunications Industry Association (CTIA), comes weeks after the Federal Drug Administration allocated $1m (£670,000) for research on the possible long-term health hazards of mobile phones.

In May, British researchers said they saw no evidence of medical risks but conceded more research was needed.

US manufacturers will have to include a pamphlet inside their packaging stating the radiation levels, measured in "specific absorption rates" (SARs) and detailing the methods used to collect that data.

Because the CTIA is an industry body, most large manufacturers support the move.
