A coordinated Korea-Japan replication study found no meaningful link between long-term RF exposure and tumors in rats at safety-standard levels, contradicting the 2018 NTP results that sparked global concern.
"The tumor increase reported by the NTP was not replicated at exposure levels that form the basis of human protection standards."
— Professor Young-Hwan Ahn, Ajou University
"The objectivity of the pathological evaluation was secured through mutual verification by experts from both countries and an international third-party peer review."
