Model		435 MHz (PW) exposure to mice and analysis of cancer and pathology (2-year bioassay)
Details		C3H/HeJ (female) mice (n=200) were exposed to 435 MHz PW (horizontally polarized with a pulse width of 1.0 usec, a pulse rate of 1.0 kHz, and a power density of 1.0 mW/cm2) for 22 hr/day, 7 day/wk for 21 months at a whole body average SAR of 0.32 W/kg. The exposure system is described in detail in a report by Banks et al. (Bioeffects of Radiofrequency Radiation on Cell Growth and Differentiation, Vol. 1, Engineering Considerations, US Air Force Armstrong Laboratory, Technical Report AL-TR-1992-0106, Brooks Air Force Base, TX, (1992). Fifty individually caged mice were positioned around the circumference of 4 waveguide systems, and an additional 200 mice were positioned around the circumference of 4 identical nonenergized waveguides to serve as controls. There was no statistically significant change in mammary tumor development, and no statistically significant increase in the incidence of any other tumor type between the exposed and sham groups. The authors concluded that the 435-MHz RF radiation did not affect the incidence of mammary tumors, tumor growth rate, latency to tumor onset, or survival relative to sham-irradiated controls. The incidence of total tumor numbers was not compared between exposed and sham exposed.
