Reducing the Electric Field in Coil Systems Used for Environmental Research

James D. Grissett · 1975

This 1975 technical study addressed a critical problem in EMF research: when scientists try to study magnetic field effects on living systems, the equipment generates unwanted electric fields that interfere with results. Researchers developed a method using multiple capacitor banks to cancel out these electric fields, allowing cleaner separation of magnetic versus electric field effects.

Protocol of inter-industry noise study

Ward WD, Gloria A · 1975

This 1975 protocol outlined a research plan to overcome major flaws in previous occupational noise exposure studies. The researchers identified three critical problems: getting accurate hearing tests without interference, finding workplaces with truly steady noise levels, and obtaining reliable exposure histories. The goal was to establish more reliable data for setting workplace noise standards.

Gonadic function in workmen with long-term exposure to microwaves

Lancranian I, Maicanescu M, Rafaila E, Klepsch I, Popescu HI · 1975

Researchers studied 31 men (average age 33) who worked around microwaves for an average of 8 years. They found that 70% experienced reduced sex drive and sexual problems, while 74% showed sperm abnormalities including poor sperm movement, low sperm count, and abnormal sperm shape. Hormone levels remained normal, suggesting the microwaves directly affected sperm production rather than hormone systems.
