This
Is A Hammer

Q: My friend told
me that if I cook food in the microwave (oven),
it will be radioactive when I take it out. He
also said standing near the microwave will cook
my insides, and people with pacemakers cant
come into my kitchen because the microwave would
make the pacemakers stop. Some of my friends have
pacemakers and use microwaves. Should I tell them
to stop using them? Grace G. in Missouri
A: Your friend is
giving you some rather sensational and untrue
information. A microwave in good condition
presents no significant danger to you or your
friends, pacemaker or not.
Note that I said
"in good condition." If the microwave
oven is damaged, if any of the interior or
exterior parts are not in place, if the rubber
door seals are deteriorated or warped or the door
doesnt close properly then do not
use it. Replace the microwave oven.
Your friends
fears about the food becoming
"radioactive" are also unfounded.
Microwave ovens work by generating radio waves
(just like a radar or X-ray). These waves pass
through the food and excite the water molecules
within. The water molecules, suddenly moving much
faster than normal, generate friction, friction
generates heat and, voila, you have hot food. The
radio waves themselves do not stay in the food.
In addition, the radiation generated by a
microwave oven is much, much less than that
generated by an X-ray at the dentists
office.
Many years ago,
pacemaker wearers were told not to stand too
close to microwave ovens because researchers were
concerned that, should stray radio waves be
emitted from the ovens during use, the radio
frequency would scramble the frequency of the
pacemaker. However, pacemakers themselves have
been shielded to prevent any kind of interference
not just from microwaves.
If youre
still concerned about radiation from the
microwave oven, follow these steps. Check the
oven for damage or a bad door seal, or replace it
with a newer model. When the oven is in
operation, stand at least 2 feet away.
A more significant
danger from microwave ovens is steam burns, which
occur most often when a covered dish is heated.
When the user opens the cover of the dish, steam
can escape rapidly, causing a painful burn.
Manufacturers recommend that covered dishes be
vented by punching a hole in the plastic wrap or
leaving the lid cracked during cooking.
