The Japanese/Korean partial repeat of the U.S. National Toxicology Project’s (NTP) RF–animal cancer study has been hit by delays. The project is two years behind schedule, with results now not expected before the middle of next year.

“We hope we will present our data” next summer at the BioEM 2026 conference in Australia, Professor Katsumi Imaida of Kagawa University, the leader of the Japanese team, told Microwave News via email. The international NTP validation project —nicknamed “NTP Lite”— is in its “final stages,” he wrote.

The project was launched in 2019 to confirm or counter the $30+ million NTP animal study, which showed “clear evidence” that RF radiation can cause cancer in rats.

“NTP Lite”: Update from Japan

The Japanese group running a partial repeat of the NTP RF cancer study has not observed genotoxic effects among male rats exposed to 900 MHz CDMA radiation at 4 W/Kg, according to a paper to be presented tomorrow at the annual meeting of the Society of Toxicology in Salt Lake City, UT (SOT2024).

The analysis of the cancer data is ongoing and will not be reported.

Korean NTP Lite: Progress Report

A Korean RF genotoxicology study —part of a joint project with Japan— has been delayed due to the unexpected death of four of the RF–exposed rats early in the accompanying two-year cancer experiment, according to Young Hwan Ahn of Ajou University medical school.

Ahn presented a progress report on the Korean arm of the project in Geneva last week at a meeting of the WHO EMF Project’s International Advisory Committee. Microwave News has obtained a copy of Ahn’s PowerPoint presentation.

Public Shut Out of GlobalRF Health Briefing

An international briefing on RF health research, known as GLORE 2020, was held online, November 9-12, featuring updates on the second phase of the U.S. National Toxicology Program (NTP) project and the Japanese-Korean partial repeat. The WHO presented a status report on ten ongoing systematic reviews of RF health effects.

Government and industry representatives from Australia, Canada, France, Japan, Korea, New Zealand and the U.S. participated, as did an assortment of academics. The public was not invited.

Everything about GLORE 2020 is being kept secret.
