microwave

 [mi´kro-wāv]
a wave typical of electromagnetic radiation between far infrared and radiowaves.

microwave

A 1–100 gigaHerz (109) wave on the electromagnetic spectrum with a wavelength of 1–1000 mm.

Public health
Exposure to microwaves is linked to domestic microwave ovens; leakage of infrared waves ranges from 1 milliWatt/cm2 at the time of sale of a microwave oven to 5 mW/cm2, measured at a distance of 2 inches. Older pacemakers tended to misfire when the wearer was exposed to early microwave ovens, which were also linked to an increase in cataracts.
 
Hazards
Mechanical—eggs and popcorn are particularly hazardous, as they can explode, and the microwaving of metallic objects can result in a fire hazard.
  
There is little data to suggest that microwave exposure is associated with increased morbidity.
