But do the microwaves stay in the oven, or do they radiate throughout the room? Should you be concerned?
Human Exposure to Microwave Radiation
If the human body is exposed to high levels of this radiation, the waves will be converted into heat, just as with food. The eyes and brain are most vulnerable to damage from this type of heat, because these organs can not cool themselves as efficiently as other organs. The cornea and lens of the eye do not have the blood vessels necessary to remove heat. The inner ear, too, has been known to sustain damage from microwave radiation, particularly as it is used in radar. Parts of the inner ear expand in response to the heat, causing clicking or buzzing sounds that interfere with normal hearing.
Some effects of excessive exposure are neurological rather than heat-related. These can include headaches, eye strain, and sleep disturbances. Since these problems are not due to microwave radiation’s effect of heat, they are probably due to exposure to an electromagnetic field.
Some experts note, however, that normally functioning microwave ovens do not emit the type or amount of radiation that is necessary for damage to the human body. Microwaves emit non-ionizing radiation, which means they do not have the ability to change materials by ionization.
Microwaves with faulty or worn out seals on their doors are the ones most likely to leak radiation. Your microwave seal may not be tight enough if there is build-up inside the microwave oven, if the seal is worn, or if the door does not close properly.
There are those who maintain that the windows of these ovens leak radiation. While this would be very low levels of the radiation, some experts claim that there are valid studies showing that low-level exposure is actually more damaging than high-level exposure.
Clearly some sort of electromagnetic field occurs around working these ovens. People with pacemakers have experienced interference from this radiation to the point that modern pacemakers are now made with an electromagnetic shield.
Some health care professionals advise their pregnant clients and patients to stay at least eight feet away from a running microwave, or to leave the room when it’s running.
