In near-field exposure to a 2450 MHz resonant slot radiator, rabbits developed cataracts at incident apparent power densities of 180 mW/cm2. Monkeys had facial burns but no lens damage even at incident apparent power densities of 500 mW/cm2; computer thermal models were reported to substantiate these results.

Microwave exposure for 2–3 minutes at SARs of only a few mW/g changed the firing rate of some Aplysia pacemaker neurons. Two response types were reported: a slow response in all neurons reaching steady state in 1–3 minutes, and a rapid response in a few neurons occurring within 5 seconds of irradiation onset. Similar responses were observed at 1.5 and 2.45 GHz, and pulsed radiation induced rapid firing-rate changes more readily than continuous-wave radiation at the same SAR; responses were not readily explained by general heating based on convective heating comparisons.

CHO-K1 cells exposed to 2450 MHz microwaves at 25 W under elevated (uncontrolled) temperature conditions showed nuclear vacuoles, pycnotic and decondensed chromosomes, and a significant increase in chromosomal breakages per cell. Cells exposed at higher incident power (75–200 W) under hypothermic conditions (29°C) showed no significant increase in nuclear vacuoles or other chromosomal anomalies versus controls. The authors state that radiation-induced temperature elevation appears essential for the observed cytological effects.

Rabbit livers were irradiated with microwaves for about 3 minutes to utilize rapid protein coagulation for potential surgical resection of fragile parenchymatous organs. Malignant tumors induced in rats were exposed to microwave radiation for 2 minutes and effects on cancer cells were observed.

Microwave radiation affected cholinesterase activity only when the temperature increase was sufficient to denature the enzyme. No direct (non-thermal) effect is described in the abstract.

After 75 mW/cm2 for 10 minutes, lens opacities were observed in 2 of 7 exposed eyes at one month. After 100 mW/cm2 exposures, chromosomal breaks per cell were reported as 0.1562 (30 min), 0.0794 (20 min), 0.0819 (10 min), and 0.0488 (5 min), while no chromosomal breaks were observed in three sham-exposed animals. The percentage of abnormal cells and chromosomal breaks per cell were higher than controls for the 100 mW/cm2, 30-minute exposure and were statistically significant at the 5% level.

The paper describes an improved fluid-filled waveguide exposure chamber with a micropipette sample holder intended to help separate apparent nonthermal microwave effects from effects due to temperature rise and to allow more precise calibration of incident and absorbed energies. Compared with control, Chinese hamster somatic cells showed a lower growth rate and differences in morphology after 2450 MHz exposure for 20 minutes at 500 mW/cm2.

No increase in blood-brain barrier permeability was observed in rats after exposure to 1.2-1.3 GHz microwave radiation at various power densities unless the rats were made hyperthermic by a warm-air environment. Microwave radiation alone did not alter permeability for fluorescein, 14C-mannitol, or serotonin.
