3、for example) and with no negative effects.To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管 ). He found that a person willstart to feel warmth at about 20 milliwatts per square centimeter (mw. / sq. cm. ) ; a satisfactory
4、feeling of warmth occurs between 35 and 50mw. / sq. cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw. / sq. cm. And a frozen meat pie in yourmicrowave oven receives about1000 mw. / sq. cm.In houses of the future, each room could be provided with its own magnetron,
5、 says Buffler.When you stepped into the living room, for example, a motion detector (运动感应器 )would turn on the magnetron, fillingthe roomwithlow-powermicrowaves.Inthe same waythat a microwave oven heats up a hamburger, but not the plate its on, you would feel warmth from the microwaves without changi
