FDA Sees No Radiation Risk in VDT Screens

No Effects Found

Eliot Marshall · 1981

Share:

The FDA's 1981 VDT screen safety assessment reflects early EMF regulation focused on thermal effects, not today's biological concerns.

Plain English Summary

Summary written for general audiences

In 1981, the FDA investigated radiation risks from video display terminals (VDT screens), examining concerns about microwave and x-ray emissions that might cause eye strain or cataracts. The agency concluded there was no radiation risk from these early computer screens. This study represents an early regulatory assessment of electromagnetic field exposure from workplace technology.

Study Details

Video display terminals do not produce levels of radiation known to be hazardous. The low-frequency waves they emit have never been shown in clinical or epidemiological studies to have any biological effect. While VDTs may cause non-radiation related health issues such as eye strain and headaches, there is no evidence of radiation-induced harm.

Quick Questions About This Study

Workers worried about microwave and x-ray emissions from video display terminals causing eye strain, cataracts, and other health effects from prolonged workplace exposure to these early computer screens.
No, the FDA concluded there was no radiation risk from video display terminals, determining that emission levels were too low to cause health effects based on 1981 safety standards.
VDT screens emitted primarily x-rays and some microwave radiation, while modern devices emit more complex radiofrequency signals at higher power levels with different exposure patterns and biological interactions.
Researchers examined eye strain, cataracts, and other vision problems among office workers using video display terminals for extended periods during the early computer workplace revolution.
It shows how regulatory agencies approached early workplace EMF concerns, using thermal-based safety standards that remain largely unchanged despite decades of biological research on non-thermal effects.
