Microwaving energy has been used in this
country to cook and heat since early
experiments with RADAR. Microwaves
themselves are in fact present in the
atmosphere all the time - both naturally
and from manmade sources. Manmade
microwaves include radar, radio and
television waves, telecommunication links
and car phones. If you follow our basic
recommendations and keep your oven
clean, then it will be completely safe.
Many years ago it was discovered that
one of the effects of microwaves is to
make water molecules VIBRATE very
quickly.
Because all foods contain water to a
greater or lesser extent, they can quickly
be heated by the friction caused by this
vibration.
Your microwave oven converts electricity
into microwaves in the magnetron.
Microwaves are REFLECTED off metal,
so they bounce off the walls and the
metal door screen, back onto the food.
They contain no heat themselves and
pass through the cooking container i.e.
are transmitted, to be ABSORBED by the
water molecules, as well as sugar and fat
particles in the food.
