What is FDA’s role concerning the safety of wireless phones?
Under the law, FDA does not review the safety of radiation–emitting consumer products
such as wireless phones before they can be sold, as it does with new drugs or medical
devices. However, the agency has authority to take action if wireless phones are shown
to emit radio frequency energy (RF) at a level that is hazardous to the user. In such a case,
FDA could require the manufacturers of wireless phones to notify users of the health
hazard and to repair, replace or recall the phones so that the hazard no longer exists.

• Cooperateinprovidingusersofwirelessphoneswiththebestpossibleinformation
on possible effects of wireless phone use on human health.
FDA belongs to an interagency working group of the federal agencies that have
responsibility for different aspects of RF safety to ensure coordinated efforts at the
federallevel.Thefollowingagenciesbelongtothisworkinggroup:
• NationalInstituteforOccupationalSafetyandHealth
• EnvironmentalProtectionAgency
• FederalCommunicationsCommission
• OccupationalSafetyandHealthAdministration
• NationalTelecommunicationsandInformationAdministration
