sparks in microwave Aluminum foil nor any other type of metal should ever be used in a microwave oven. The radio frequency energy that the magnetron generates will not penetrate the metal and WILL cause sparks where it bleeds off the metal surface. This is detrimental to the life of the magnetron.
The term nukes is totally in error. There is NO nuclear radiation associated with a microwave oven. It is the same type of energy that your cell phone, cordless phone, CB radio, the local radio, tv station and radar and all other types of radio devices emit. The only differences between a microwave oven and these other types of devices is the frequency of the energy and the power it is emitted at. |
