Radio Frequency and Microwave Radiation
Authors not listed · 1972
The 1972 guide summarizes microwave biological effects and provides ANSI recommended maximum exposure of 10 mW/cm².
Plain English Summary
The guide defines radio frequency and microwave bands from 10 MHz to 300 GHz and describes common sources such as radar, communication systems, medical diathermy, and microwave ovens. It explains that microwaves interact with tissue mainly by converting electromagnetic energy to heat, with penetration depth depending on wavelength. ANSI recommends a maximum power density of 10 mW/cm² for exposures of 0.1 hour or more. ACGIH sets a threshold limit value of 10 mW/cm² for continuous exposure and 25 mW/cm² for intermittent exposure.
Why This Matters
The guide notes that high-voltage electron tubes in microwave transmitters can produce x-rays as an unintended byproduct. Soviet investigators suggested microwaves may affect the central nervous system at molecular and cellular levels without significant heating.
Exposure Information
Specific exposure levels were not quantified in this study.
