NTP Lite: The Japan-Korea Collaborative RF Exposure Toxicity Project [Health Matters]

This magazine article reviews the Japan-Korea "NTP Lite" RF animal toxicity collaboration and its relationship to prior NTP (2018) and Ramazzini Institute reports of RF-associated tumors in male rats. It notes NTP Lite used a single whole-body SAR of 4 W/kg and completed a two-year exposure phase in 2022, but final…

Toxicology and carcinogenesis studies in Sprague Dawley (Hsd:Sprague Dawley SD) rats exposed to whole-body radio frequency radiation at a frequency (900 MHz) and modulations (GSM and CDMA) used by cell phones

This National Toxicology Program technical report describes 900 MHz whole-body RFR exposures (GSM and CDMA) in male and female Sprague Dawley rats from in utero through up to 2 years. The report concludes clear evidence of carcinogenic activity in males for both modulations based on malignant schwannoma of the heart,…

NTP Technical Report on the Toxicology and Carcinogenesis Studies: GSM- and CDMA-modulated Cell Phone RFR, NTP TR 595

This NTP technical report describes long-term rat studies exposing animals to 900 MHz GSM and CDMA-modulated radiofrequency radiation at whole-body SAR levels of 0, 1.5, 3, and 6 W/kg, including exposure beginning before birth. The abstract reports NTP concluded there was "clear evidence" for malignant schwannoma of…
