Radiofrequency radiation (RFR) was classified as a “possible” human carcinogen in 2011, which caused great public concern. A carcinogenicity study by the National Toxicology Program (NTP) found Code Division Multiple Access—and Global System for Mobile Communications—modulated mobile phone RFR to be carcinogenic to the brain and heart of male rats. As part of an investigation of mobile phone carcinogenesis, and to verify the NTP study results, a 5‐year collaborative animal project was started in Korea and Japan in 2019. An international animal study of this type has two prerequisites: use of the same study protocol and the same RF‐exposure system. This article discusses our experience in the design of this global study on radiofrequency electromagnetic fields (RF‐EMFs).© 2022 The Authors.
