Researchers at the State University at Buffalo irradiated rats with single doses ranging from .05 to 1.5 roentgen and measured red cell precursor production. Doses of .15 roentgen and above caused a sudden increase in precursor numbers but at a lower rate than in nonirradiated rats. The marrow's ability to produce normal precursor numbers had not recovered at 5, 13, or 30 weeks after exposure.

Diathermy applies high-frequency electromagnetic energy to generate heat in body tissues. Surgical diathermy destroys tissues, while therapeutic diathermy warms them without damage. The effectiveness of therapeutic diathermy has been widely debated, and claims for it are often exaggerated or poorly supported by reliable clinical data.

Researchers exposed Japanese quail embryos to 2.45 GHz microwaves at 5 mW/cm2 or 20 mW/cm2 for the first 8 days of development. Neither exposure level caused changes in embryonic heart morphology or myocardial ultrastructure. Lactate dehydrogenase and glutamic-oxaloacetic transaminase activities did not differ from controls. Creatine phosphokinase activity was lower at 20 mW/cm2 compared to control, but unchanged at 5 mW/cm2.

Researchers measured internal electric field distributions in phantom human heads exposed to leakage radiation from 2450 MHz and 915 MHz microwave ovens. The phantom heads were made from actual adult and child skulls filled with dielectric materials matching the electrical properties of muscle or brain. For 5 mW/cm² leakage at 2450 MHz, the maximum equivalent dose rate was 9.6 W/kg in the adult phantom and 14.6 W/kg in the child phantom. For 5 mW/cm² leakage at 915 MHz, the maximum equivalent dose rate was 3.0 W/kg in the adult phantom and 5.3 W/kg in the child phantom.

The thesis aimed to improve protection for military personnel and the public from electromagnetic radiation hazards of military communications and radar systems across the 30 Hz to 300 Giga-hertz spectrum. The thesis detailed military involvement with EMR-emitting systems including submarine communications, radar, microwave food processing, and extremely low frequency communications. A comparison of protective measures across services identified areas where some services were not using measures employed by others.

Researchers trained unfettered Macaca mulatta monkeys to hold their heads in a pulsed microwave beam at 9.31 GHz and 150 mW/cm?. Twelve monkeys were irradiated individually without restraint or anesthesia during 30 to 40 sessions and then observed for one year.

Researchers treated ten patients with superficial metastatic tumors using microwave hyperthermia at 2450 MHz. Hyperthermia was delivered at 43°C for 45 minutes using a dielectrically loaded tapered or conformal wave guide applicator. Heat alone produced one complete response, one partial response, and one minor response among the 10 patients. Five lesions that did not respond to heat alone were then treated with hyperthermia plus radiation therapy, resulting in three complete responses and two partial responses.

Researchers used Sprague-Dawley male rats to study the tolerance of the blood-brain barrier to microwave irradiation at 2450 MHz. Horseradish peroxidase was administered 30 minutes before sacrifice to assess barrier disruption, and brains were analyzed after perfusion. In normothermic rats, the barrier was disrupted after 10 minutes at 45°C, 15 minutes at 42°C, and 60 minutes at 40°C; in hypothermic rats, disruption occurred after longer durations at the same temperatures.

Researchers exposed C3H mice to 148 MHz RF energy at 0.5 mW/cm2 for one hour a day, five days a week, for 10 weeks starting shortly after birth. They monitored body weight daily for ten weeks then weekly, drew blood at multiple ages for analysis, and performed necropsy with histopathology on randomly selected animals. No effects were found on blood cells, body mass, or lesion incidence, onset, prevalence, extent, or type compared to sham controls.
