This research contributed to the growing body of evidence that electromagnetic fields can produce measurable changes in human blood parameters.
Z. V. Gordon et al. · 1969
Soviet researchers exposed albino rats to millimeter wave radiation and found it weakened their nervous system function, altered blood pressure, and caused structural changes in their brains. This 1969 study was among the first to show that millimeter waves, which are absorbed primarily by surface tissues, can still affect deep internal organs. The findings suggest these frequencies may have different biological effects compared to longer wavelengths.
Christopher H. Dodge · 1969
This 1969 review by Christopher Dodge examined hundreds of Soviet and Eastern European studies on microwave radiation effects in humans, focusing on clinical studies and workplace exposure surveys. The review highlighted significant findings from communist bloc research that was largely unknown in the West. This work revealed decades of human research showing biological effects from radiofrequency radiation exposure.

Unknown authors · 1969
This 1969 journal publication examined non-ionizing radiation across multiple frequency ranges including radiofrequency, microwave, infrared, and visible light. The research represents early scientific investigation into the biological effects of electromagnetic fields that don't carry enough energy to ionize atoms. This foundational work helped establish the scientific framework for understanding EMF health effects that continues today.
Stephen Herrero · 1969
Researchers used radiofrequency current to create precise brain lesions in female rats' ventromedial hypothalamus, finding that RF lesions caused identical effects to direct current lesions. All 15 rats with RF-induced brain damage developed obesity, along with disrupted hormone cycles, reduced activity, and increased water consumption. This 1969 study demonstrates that radiofrequency energy can cause permanent, measurable brain damage in living tissue.

This 1969 journal article provided a comprehensive review of non-ionizing radiation across the electromagnetic spectrum, covering radio frequency, microwave, infrared, and visible light. The research examined the biological effects and safety considerations of these radiation types, which don't have enough energy to remove electrons from atoms. This early review helped establish foundational understanding of how different frequencies of electromagnetic energy interact with living systems.

B. I. KHODOROV, E. M. PEGANOV · 1969
Researchers tested how different metal ions (calcium, magnesium, barium, nickel, and lanthanum) affect nerve cell electrical responses in frog nerve fibers. They found that these positively charged particles are essential for normal nerve function, with some metals like lanthanum being much more effective than others at stabilizing nerve membranes.

Researchers in 1969 developed a microwave-based method to kill three common grain insects (flour beetles, granary weevils, and rusty grain beetles) while simultaneously drying wheat.

Researchers exposed isolated frog muscle tissue to a permanent magnetic field of 2200 Oersted and found that while the basic stimulation threshold remained unchanged, the variability in that threshold increased significantly. This suggests magnetic fields can create 'interference' effects in biological tissues even when they don't alter the primary response.
