Abstract

An International Collaborative Animal Study of the Carcinogenicity of Mobile Phone Radiofrequency Radiation: Considerations for Preparation of a Global Project Ahn YH, Imaida K, Kim YB, Han KH, Pack JK, Kim N, Jeon SB, Lee AK, Choi HD, Wang J, Kawabe M, Kim HS. An International Collaborative Animal Study of the Carcinogenicity of Mobile Phone Radiofrequency Radiation: Considerations for Preparation of a Global Project. Bioelectromagnetics. 2022 Apr 27. doi: 10.1002/bem.22407 Abstract 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). pubmed.ncbi.nlm.nih.gov

Main findings

The article describes considerations and experience in designing an international collaborative animal study to investigate mobile phone RF-EMF carcinogenicity and to verify prior NTP study results. It notes that the NTP study found CDMA- and GSM-modulated mobile phone RFR to be carcinogenic to the brain and heart of male rats, and emphasizes the need for a shared protocol and RF-exposure system for the global project.

Outcomes measured

  • carcinogenicity
  • brain cancer/tumors (male rats; referenced NTP findings)
  • heart cancer/tumors (male rats; referenced NTP findings)

Limitations

  • Appears to be a planning/considerations article rather than reporting new carcinogenicity results from the collaborative project
  • No exposure metrics (e.g., frequency, SAR) reported in the abstract
  • No sample size or outcome results for the Korea/Japan project reported in the abstract
