What do microwaves do to humans

Are microwave containers risky? Does microwave radiation make foods radioactive? But is this true? What is radiation? Have you ever thought about what radiation actually is? Have you ever had an x-ray? Ever used a sunbed? Also radiation. Your mobile phone gives off radiation, as do computers, heaters, and radios. Firstly, it is important to understand how a microwave works. How do microwaves work?

What does this mean? So, is microwave radiation harmful? But is there any good evidence to support this theory? What have we learned? They just heat them!

We will not be writing about the taste of dishes, because that is a matter of preference, but will instead focus on how microwaves work and how they heat dishes. As the name of the device suggests, microwaves heat meals using electromagnetic radiation with a wavelength of about 12 cm.

They start to oscillate rotational oscillation absorbing the energy of the absorbed microwaves. However, these vibrations are strongly suppressed by other substances chemicals surrounding the water molecules contained in the meal that is being heated.

As a result of this mechanical interaction resembling the behaviour of a mixer in a dough bowl , the previously absorbed energy is transferred back to the meal, with which the microwave radiation does not interact directly, causing it to heat up. Also, the warming of the container is a secondary effect, as microwave containers do not absorb radiation of such frequencies.

Microwave radiation creates a standing wave inside the oven, magnetron waves emanate from the opposite side of the oven. This means that some places in the dish will be heated significantly where the arrows of the standing wave, i. To avoid such uneven heating of dishes, they are placed on rotating stands or an additional rotating reflector is used and changes the distribution of intensity within the oven. The phenomenon of microwave interactions with food water was accidentally discovered by the American Percy Spencer [7] while he was working on the construction of radar equipment.

When experimenting with a magnetron, which is the source of microwaves also in the home appliance, he felt that the chocolate bar in his trousers started melting.

On the other hand, an egg exposed to microwaves exploded. These troublesome events made it possible for him to launch the first microwave oven in The first devices were water-cooled which meant that their use was restricted to bars and restaurants only. There are a lot of opinions about the harmfulness of food that is prepared using microwave ovens as well as their negative impact on people nearby. However, research [8] has shown that no chemical changes changes in molecular structure occurred as a result of the microwaves passing through the food.

Also, microwaves do not have a significant impact on the health and well-being of their users. The properties of the cage are not negated even if a glass plastic door is used through which we can observe the dishes inside. This is because the door is covered with a metal mesh that is considerably smaller than the microwave wavelength, which prevents the waves from being emitted outside of the oven. Opening the door automatically turns the device off. Prog Biophys Mol Biol.
