Martin Lubin et al. · 1960
Researchers exposed rabbits and rats to repeated doses of 400 MHz whole-body radiation and found no detectable tissue damage in surviving animals. This 1960 study contrasted with higher frequency radiation (3,000 MHz) which readily caused cataracts, suggesting frequency matters for biological effects. The authors cautioned their findings don't rule out subtle damage they didn't test for.
Michaelson et al. · 1960
This 1960 study examined dogs that survived ionizing radiation exposure and later received microwave radiation at 2850 MHz. The research found that previously irradiated dogs showed increased susceptibility to microwave-induced hyperthermia (overheating), altered blood flow responses, and higher rates of localized burns. The findings suggest that prior radiation exposure can make organisms more vulnerable to electromagnetic field effects.

E. HENDLER, J. D. HARDY · 1960
Researchers exposed seven people's foreheads to controlled infrared and microwave heating while measuring skin temperature. They found that temperature sensations correlated with how fast skin temperature changed, not the absolute temperature itself. This suggests our temperature sensors respond to the rate of change rather than static heat levels.
