 Microwave Myths 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. |
