This study was performed in the framework of the Cooperative Research and Development Agreement (CRADA) between the Cellular Telecommunications and Internet Association (CTIA) and the US FDA.

Human peripheral blood lymphocytes were exposed for 24 hours to RFR at 900 MHz frequency at four SARS (0, 1, 5, and 10 W/Kg). The cytokinesis-block assay was used to evaluate cell proliferation and micronuclei frequency. The exposed cells were compared with sham controls and with positive controls exposed to mitomycin C. Two research groups performed the same study and results were assessed independently by two observers, one from each laboratory.

There was no evidence of genotoxic or cytotoxic effects from the RFR exposure. This was true in the individual laboratories and when the slides were cross-checked by the two observers.
