Pregnant CFLP mice were exposed to 2.45 GHz microwave radiation for 100 minutes each day throughout gestation in an anechoic chamber. Brain aminoacyl-tRNA synthetase activity decreased significantly after continuous-wave exposure but not after amplitude-modulated exposure. Liver enzyme activity increased after both continuous-wave and amplitude-modulated exposure, while body and organ weights were unaffected.

A solution of rat muscle actomyosin was exposed to 2375 MHz pulse-modulated microwave radiation with rectangular pulse modulation ranging from 50 to 300 pulses per second. The study found that actomyosin ATPase activity was dependent on both modulation frequency and microwave intensity. Specific modulation frequencies were found to change the ATPase activity of actomyosin.

The study aimed to investigate the effect of ultrahigh-frequency electromagnetic radiation on learning and memory processes. Low-intensity electromagnetic field (12.6 cm, 2375 MHz, power density 1 mW/cm2) produced retrograde amnesia in the rat passive avoidance test. No effect was registered of microwave irradiation on the open field behavior and the pain sensitivity.

Researchers studied whether exposure to low-intensity radiofrequency radiation after a lethal dose of gamma-radiation could modify the resulting injury in mice. The radiofrequency exposure lasted up to 23 hours at an intensity of 5 plus or minus 1.5 microwatts per square centimeter, covering frequency ranges of 2-8, 8-18, and 19-27 GHz with a swing frequency of 12-14 Hz. A clearly pronounced modification of acute radiation injury was obtained when the radiofrequency exposure was applied immediately after the gamma-radiation.

Researchers exposed rats to microwaves at 2375 MHz with a power density of 1 mW/cm2 and found that this induced retrograde amnesia. The study found roles for opioidergic, benzodiazepine, GABAergic, and cholinergic components in the memory-impairing effects of microwaves. Piracetam and oxiracetam each prevented the negative effects of microwaves on memory processes in the rats.

French researchers exposed mice to low-power pulsed microwaves (similar to radar frequencies) for 10 hours daily over five days to test effects on immune system function. They found that simple pulsed signals had little effect, but when the signals included additional amplitude modulation, the mice showed significant changes in antibody production - some frequencies strengthened immune responses while others weakened them.

Researchers studied chromosome damage in 38 radio-linemen exposed to radio-frequency radiation and 38 matched controls. They analyzed Two hundred metaphases per person, scored blind, and found the rate of aberrant cells was the same in both groups. There were no statistically significant differences in the types of chromosome aberrations.

Researchers exposed fourteen male Belgian white rabbits to microwave radiation at 5 mW/cm2, 2.1 GHz, three hours daily, six days a week for three months, while seven rabbits received sham exposure for the same duration. Significant suppression of T lymphocyte numbers was found in the microwave group at two months and during follow-up. Despite lower T lymphocyte counts in the blood, no significant variation was observed in tissue T lymphocyte counts, and a functional immune response test showed no impairment.

Researchers exposed actively growing cultures of C3H/10T1/2 cells for 24 hours to 2.45-GHz microwaves pulse-modulated at 120 Hz. The electromagnetic fields alone had no effect on cell survival or induction of neoplastic transformation. When combined with the tumor promoter TPA, the enhancement of transformation was highly significant and ranged up to a level equivalent to that produced by 1.5 Gy of X rays. The frequency of neoplastic transformation was dependent on the level of electromagnetic exposure and was additive with doses of X rays given as a cocarcinogen.

Two experiments tested whether frequency-specific hotspot formation in the body and tail of rats would have behavioral consequences. Rats were placed in a cage where occupying one side triggered microwave exposure and occupying the other side ended it. Reduced exposure to 360-MHz and 2450-MHz microwaves at 1, 2, 6 and 10 W/kg were significantly different from 700-MHz microwaves. A second experiment found the threshold for reduced exposure to 2450-MHz microwaves fell between whole-body SARs of 2.1 and 2.8 W/kg.

Purified plasmid DNA was exposed to microwave radiation at nonthermal levels in the frequency range from 2.00 to 8.75 GHz. The exposure produced single- and double-strand breaks detected by agarose gel electrophoresis. Microwave-induced DNA damage depended on the presence of small amounts of copper. The effect was dependent on both microwave power and exposure duration. Cuprous ions, but not cupric ions, mimicked the microwave effects on DNA.

The EPA proposed four alternative approaches to limit public exposure to radiofrequency radiation. Three options are regulatory and would set whole-body average SAR limits of 0.04, 0.08, and 0.4 W/kg for frequencies above 3 MHz. For frequencies below 3 MHz, the regulatory options would limit electric field intensity to 87, 275, and 614 V/m and magnetic field intensity to 0.23, 0.73, and -1.63 A/m respectively. The fourth option is nonregulatory and would use information and technical assistance programs instead of adopting Federal Guidance.

The article reports that West Germany published its first official human-exposure guidelines for electromagnetic fields, applicable to both workers and the general public. The German standard covers frequencies from 0.01 MHz to 3900 GHz, which is wider than the ANSI standard’s 0.1 MHz to 100 GHz range.

The review evaluates the World Health Organization's Environmental Health Criteria 16 document on radiofrequency and microwave fields from 100 kHz to 300 GHz. The reviewer finds the publication unbalanced because it accepts nonthermal interaction literature with cursory critique while neglecting refuting evidence. The review notes that the document's designations of high, medium, and low power densities are ambiguous and ignore the frequency dependence of bioeffects. It points out specific errors in Table 10 frequency designations and an incomplete discussion of chronic cataract studies that omitted rabbit and monkey data showing no ocular damage. The reviewer concludes the document does not meet the high scientific caliber and accuracy of usual WHO publications.

This 1980 FDA research by H. Bassen examined radio-frequency and microwave radiation exposure measurement and safety standards. The study focused on how these electromagnetic fields are absorbed by human tissue and established methods for assessing exposure levels. This represents early foundational work in understanding RF/microwave radiation effects on human health.
