Researchers conducted provocation tests on two patients who claimed to suffer skin problems from computer screen exposure. The study found high numbers of specific immune cells (mast cells and somatostatin-positive cells) in skin biopsies, with changes occurring after TV screen exposure. The authors suggest these cellular changes may explain symptoms like itching, pain, swelling and redness that some people experience around electronic displays.

Researchers exposed mice to 1.25 GHz microwave radiation and found the animals made involuntary movements even when heating was minimal (less than 0.1°C). This shows biological systems can detect and respond to microwave energy below levels that cause measurable heating.

Researchers documented severe eye damage in a 44-year-old man who was accidentally exposed to high-energy microwave radiation. The exposure caused lasting vision problems including abnormal color perception, reduced retinal function, and visual blurring that persisted for at least two years. This case demonstrates that microwave radiation can cause permanent damage to the delicate structures of the human eye.

Researchers exposed rats to microwave radiation (2450 MHz) for 45 minutes and measured changes in brain receptors that respond to anxiety and stress. A single exposure increased these stress-related receptors in the brain's cortex, but repeated exposures over 10 days showed the brain adapted to the radiation. The findings suggest that microwave radiation at levels similar to some wireless devices can trigger a stress response in the brain.

Nine telecommunications workers were accidentally exposed to 4.1 GHz radio-frequency radiation, with two receiving high doses of 4.6 mW/cm² for up to 90 minutes. Despite comprehensive medical examinations and nine months of follow-up, researchers found no harmful health effects except possibly hair loss.

This 1985 study measured the electrical environment around computer monitors (VDTs) to investigate reports of skin rashes and health complaints among operators. Researchers found that VDTs reduced beneficial negative ions in their immediate vicinity and created DC electric fields up to 5,000 volts per meter at close range, though these levels were comparable to common indoor electrical charges.

This 1982 government report documented radiation incidents involving visual display terminals (VDTs), the early computer monitors used in offices. The registry tracked health complaints including cataracts, eye strain, and headaches reported by workers using these devices. This represents one of the earliest systematic efforts to monitor occupational health effects from electronic display technology.
Om P. Gandhi · 1982
In 1982, the IEEE examined radiation emissions from video display terminals (VDTs) and concluded that all radiation levels fell well below safety standards. The organization attributed user health concerns to workplace stress rather than EMF exposure, dismissing radiation risks as misconceptions based on erroneous beliefs.
Brian Alley, Charles Wallach · 1982
This 1982 research examined health risks from prolonged use of cathode ray tube (CRT) video display terminals, focusing on ion depletion and electrostatic charge effects. The study explored whether CRT screens create unhealthy air conditions through negative ion reduction and static electricity buildup. This early computer health research helped establish workplace safety guidelines for office workers spending hours at computer screens.
Charles Wallach · 1982
This 1982 study examined health complaints from computer and TV screen operators, finding DC voltage gradients up to 50,000 volts per meter between users' faces and screens. Researchers linked common symptoms like headaches, eye irritation, and pregnancy complications to the screens' positive electrical charge disrupting natural air ions.

This 1982 conference paper examined the health effects of cathode ray tube (CRT) video displays, which were the dominant computer and television screens of that era. The research focused on electromagnetic emissions from these displays and their potential impact on human health, including sensory effects and microwave radiation exposure.
Charles Wallach · 1982
This 1982 study examined health effects from cathode ray tube (CRT) displays used in computers, televisions, and video games. Researchers found that CRT screens create electrical fields up to 50,000 volts per meter near users' faces and linked these displays to eye irritation, headaches, nausea, and pregnancy complications. The study suggested that positive electrical charges from CRT screens disrupt natural air ions, creating an unhealthy breathing environment for operators.

This 1981 study investigated mysterious facial rashes experienced by computer monitor operators. Researchers found that electric fields from old-style cathode ray tube displays dramatically increased the deposition of irritating particles onto users' skin. Under conditions where rashes occurred, particle exposure increased by at least 10 times normal levels.
