CONSIDERATIONS AND CRITERIA FOR A RECOMMENDED STANDARD FOR OCCUPATIONAL EXPOSURE TO RADIOFREQUENCY AND MICROWAVE FIELDS
Authors not listed · 1978
NIOSH recognized RF/microwave workplace hazards requiring protection standards in 1978, decades before widespread consumer wireless adoption.
Plain English Summary
This 1978 NIOSH technical report established criteria and considerations for recommended standards protecting workers from radiofrequency and microwave field exposures. The document addressed occupational safety limits for RF/microwave radiation in workplace environments. This represents early government recognition that RF and microwave exposures required formal worker protection standards.
Why This Matters
What makes this 1978 NIOSH report particularly significant is its timing and source. The National Institute for Occupational Safety and Health was already recognizing that radiofrequency and microwave fields posed enough of a workplace hazard to warrant formal exposure standards. This wasn't industry self-regulation or academic speculation - this was the federal agency responsible for worker safety determining that RF/microwave protection was necessary.
The reality is that workplace RF exposures in 1978 were often orders of magnitude higher than what most people experience today from consumer devices. Yet NIOSH still felt compelled to establish protective standards. Today's ubiquitous wireless devices may operate at lower power levels, but they expose the general population - including children - to RF fields that concerned occupational safety experts decades ago. The science demonstrating biological effects has only grown stronger since then.

The recommended standard is frequency dependent, with the greatest concern in the 10-500 MHz range where maximum human absorption occurs. The standard should avoid exposure levels that cause net rise in body temperature (10 mW/sq cm). A cautious approach is recommended pending further research on nonthermal effects. Engineering controls, monitoring, and medical surveillance are essential components of the recommended standard.
