Are Microwaves Safe?
Microwave ovens save time, money and energy in that they cook or heat up prepared meals in a fraction of the time it takes to cook food manually. Have you ever wondered about how they perform this feat and if the process is good for you? There is a lot of misinformation out there. Here you can find out the answers to those questions and more.
How Do Microwaves Work?
Microwave ovens release microwaves that pass through rf couplers in the oven and cause the water molecules within your food to vibrate. This vibration generates heat, which drastically speeds the heating time for food. This process generates radiofrequency radiation (RF). RF is basically the energy that is released from a source, which can vary depending on the level of frequency in which it lies on the electromagnetic spectrum.
What You Should Know About the Electromagnetic Spectrum
The higher something moves up in frequency along the electromagnetic spectrum, the more dangerous it becomes. At higher frequencies, the composition of the cell DNA is altered, which is what can cause cancer. Things like gamma rays and x-rays have higher frequencies and should be limited or avoided. This type of radiation is called ionizing radiation and it harms the DNA of the cell by chemically altering and removing an electron.
Where Are Microwaves on the Electromagnetic Spectrum
Microwaves are low on the electromagnetic spectrum. Microwaves cause the water molecules within cells to vibrate and heat up, but they aren’t high enough frequency to remove an electron or change the molecular composition of your food. Ovens are made to distribute microwaves only when the doors are shut and the unit is working. If you have an older microwave that is damaged, you may want to ensure you don’t have a leak, though.
Microwaves are safe to use and non-carcinogenic for people. They heat food safely and with low enough frequencies that cause no harm. So heat up those leftovers and eat guilt-free.
