Dr. Albert Krueger's 1973 research examined how air ion concentrations affect human health and comfort. The study found that ion-depleted indoor air may cause anxiety, discomfort, reduced efficiency, and increased respiratory infection risk. Positive ion excess was linked to the ill effects of notorious winds like the Sharav and Föhn.

This 1972 study proposed that UHF microwave radiation creates thermal gradients in the inner ear's balance organs (semicircular canals), triggering dizziness and eye movements that mimic motion sickness. The research estimated humans would experience these vestibular effects at 34 mW/cm² exposure levels, suggesting the inner ear is particularly sensitive to microwave heating.

Researchers exposed 100 rhesus monkey eyes to pulsed laser radiation at 1.06 micrometers to determine retinal damage thresholds. They tested single pulses versus multiple pulse trains at 10 and 20 pulses per second. No cumulative damage effect was found - multiple pulses caused no more retinal damage than single pulses of equivalent peak energy.
G. Fischer · 1973
Researchers in 1973 studied how artificial electrostatic fields affect animal physiology and found that positively charged constant fields increased liver activity, oxygen consumption, and immune system readiness. When animals were shielded from these fields in Faraday cages, the opposite effects occurred. The study suggests that natural atmospheric electrical fields may play an important role in maintaining health and metabolism.

This 1973 study tested whether 2450 MHz microwave radiation (the same frequency used in microwave ovens) could stimulate growth in mice. Researchers found no growth-stimulating effects from chronic exposure to this frequency. The study specifically refuted earlier claims that low-power microwave radiation could enhance biological growth.

This 1972 study examined how 2450 MHz microwave fields (the same frequency used in microwave ovens) interact with temperature measurement devices like thermocouples and thermistors. Researchers found that microwave radiation at 100 mW/cm² interfered with these measuring instruments, affecting their accuracy whether they were shielded or unshielded.

This 1973 review examined the major controversy surrounding microwave radiation health effects and safety standards. The study found significant philosophical differences between Western and Soviet approaches to microwave exposure limits. The author suggested that East-West cooperation could help resolve ongoing debates about microwave safety.
James L. Lords et al. · 1973
Researchers exposed isolated hearts from cold-blooded animals to 960 MHz microwave radiation and found it caused the hearts to beat slower (bradycardia), which is the opposite of what normally happens when hearts are heated. This unexpected effect only occurred at very specific power levels around 3 milliwatts absorbed by the heart tissue.

Researchers exposed bacteria (E. coli and Pseudomonas) to 2450 MHz microwave radiation at 60 mW/cm² for 12 hours to study effects on growth. They found no impact on bacterial reproduction rates beyond what could be explained by temperature changes. This suggests microwave radiation at this frequency may not directly disrupt cellular processes in these microorganisms.

Researchers tested how rats of different sizes absorbed radiofrequency energy (285-4000 MHz) when positioned in different orientations. They found that body position dramatically affects absorption, with vertical orientation absorbing 10 times more RF energy than horizontal positions. Larger animals showed peak absorption at lower frequencies, following predictable mathematical relationships based on body weight.
