Cell Phones

The draft NTP Technical Reports on rats and mice were reviewed by an external expert panel in March 2018. Meeting materials, including panel actions, are on the meeting webpage. The final NTP Technical Reports are expected in fall 2018.

Cell phones are currently used by 95 percent of American adults, according to a 2016 survey. While current scientific evidence has not conclusively linked cell phones with any health problems, NTP and other scientific organizations recognize that additional data are needed.

Therefore, NTP has conducted studies to help clarify any potential health hazards, including cancer risk, from exposure to cell phone radiofrequency radiation, and to better inform protection for public health.

The nomination for NTP to study cell phone radiofrequency radiation (RFR) was made by the U.S. Food and Drug Administration (FDA) because of the following:

    • Human exposure is widespread.
    • Current exposure guidelines are based largely on protection from acute injury from thermal effects.
    • Little is known about potential health effects of long-term exposure to cell phone radiofrequency radiation.
    • Currently available human studies have found limited evidence of an increased risk of cancer from cell phone use.
