The publication explains that microwaves are a nonionizing form of electromagnetic energy between radio waves and infrared waves. Most studies have shown no significant nutritional differences between microwave and conventional cooking methods. No documented radiation injuries have occurred from microwave ovens used according to manufacturer instructions, although pacemaker interference has been associated with proximity to operating ovens. The FDA established a radiation control standard requiring ovens manufactured after October 6, 1971 to limit emissions and have two safety interlocks. Ovens meeting the federal standard are considered safe for home use when operated according to instructions.

The mean daily irradiation value was 30.7 with a range of 6.5 to 97.1, and the measurement error was stated as + 30%. No significant differences in EEG findings were found between the exposed group and the control group. A significant coincidence was found between headache incidence and EEG abnormality percentage, particularly for migraine. The authors concluded that electromagnetic energy at the exposure dose did not damage the central nervous system and that EEG abnormalities should be assessed in relation to migraine incidence.

Researchers exposed fertilized chicken eggs to a 26-kHz, 160-gauss peak-to-peak alternating current field for 19 days while keeping control eggs under identical conditions without the field. The hatch rate was 64.5% for exposed eggs and 48.5% for controls. Statistical analysis yielded a Z-value of 1.79 with a probability of 0.0367, leading to rejection of the hypothesis that the field reduces hatching at the 5% significance level. No gross abnormalities were found in dead embryos, and all hatched chicks appeared normal during 36 hours of observation.

Researchers used a newly developed waveguide facility to pipe microwaves to mice to examine the potential for congenital abnormalities. The study observed effects including exencephaly (brain hernia), stunting of offspring, and bone marrow abnormalities.

Researchers used a Q-switched neodymium laser at 1.06 µm to determine retinal damage thresholds in 100 rhesus monkey eyes. Each eye was exposed to five pulse configurations: single pulse, 10 pps for 0.5 sec, 10 pps for 1 sec, 20 pps for 0.5 sec, and 20 pps for 1 sec. Probit analysis showed no significant difference between the single-pulse ED-50 and the peak-pulse ED-50s in any pulse train. For average pulse energy, the 20 pps 0.5 sec and 20 pps 1 sec ED-50s were significantly lower than the single-pulse ED-50.

Researchers exposed NMRI-Hahn mice to a constant electrostatic field of 24000 Volt/m, a Faraday cage, or normal lab conditions for 10 days and measured total activity, food intake, and water consumption. Total activity increased in the electrostatic field and decreased in the Faraday cage, with differences highly significant (p = < 0,001). Liver oxygen consumption was significantly higher in mice from the field chamber and lower in mice from the Faraday cage compared to controls. After 15 days exposure to fields of 40, 200, 1000, 5000, and 24000 V/m, plaque-forming cells in the spleen increased most at 1000–5000 V/m, while the Faraday cage reduced plaque counts below control levels. Rectal temperature rose from 37,5°C to 37,8°C in mice exposed to the field for 20 days.

The study evaluated the interaction of a 2450-MHz continuous wave microwave field with shielded and unshielded thermistors and thermocouples at a power level of 100 mW/cm?. Thermistors gave repeatable temperature profiles with no detectable interaction regardless of shielding or lead orientation. Unshielded thermocouples produced non-repeatable measurements with sudden temperature jumps and more variation when leads were parallel to the electric field. The authors concluded that thermistors were accurate detectors for temperature measurement while thermocouples produced erroneous information due to interaction with the microwave field.
