NIOSH conducted a 1978 workplace survey at a Connecticut company to measure RF radiation from industrial heat sealers and identify workers for potential health studies. They found that 10 of 11 heat sealers produced electric field levels exceeding 200 V/M, well above typical background levels. This survey was part of early efforts to understand occupational RF exposure risks before widespread wireless technology adoption.

Researchers exposed muscle tissue from chicks to a 0.7 tesla magnetic field for up to 60 minutes, then measured calcium transport in cellular structures. They found that longer magnetic field exposure increased both the rate and total amount of calcium uptake by the muscle cells. This suggests magnetic fields can alter fundamental cellular processes that control muscle contraction.

Researchers trained 12 monkeys to expose their faces and eyes to 9.31 GHz microwave radiation at 150 mW/cm² for 30-40 sessions, then monitored them for one year. No eye damage or cataracts developed from this high-frequency microwave exposure. This study examined whether microwave radiation at frequencies used in some radar and communication systems could cause eye injury.

This 1979 review by H.P. Schwan traces the history of microwave and radiowave biological effects research from the 1930s onward.
