Glioma in rat brain (credit: Samuel Samnick et al./European Journal of Nuclear Medicine)
A series of studies over two years with rodents exposed to radio frequency radiation (RFR) found low incidences of malignant gliomas (tumors of glial support cells) in the brain and schwannoma tumors in the heart.*
The studies were performed under the auspices of the U.S. National Toxicology Program (NTP).
