Health Impacts- Sierra
Negative: May cause memory loss, adhd, headaches, and infertility
Being on the phone with it up to your face for 50 minutes alters your cerebral glucose metabolism
Long exposures to microwaves may cause cataracts in your eyes. This is a clouding of the lense keeping you from seeing clearly.
Positives: It cooks food well lowering your chance of getting food borne illness
Microwaves can reduce the amount of vitamins and minerals lost while cooking.
Interesting article : What is Microwave Radiation?-Anna
Microwaves are a form of "electromagnetic" radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation ranges from the energetic x-rays to the less energetic radio frequency waves used in broadcasting. Microwaves fall into the radio frequency band of electromagnetic radiation. Microwaves should not be confused with x-rays, which are more powerful.
Microwaves have three characteristics that allow them to be used in cooking: they are reflected by metal; they pass through glass, paper, plastic, and similar materials; and they are absorbed by foods. The standard also requires all ovens to have two independent interlock systems that stop the production of microwaves the moment the latch is released or the door opened. In addition, a monitoring system stops oven operation in case one or both of the interlock systems fail. The noise that many ovens continue to make after the door is open is usually the fan. The noise does not mean that microwaves are being produced. There is no residual radiation remaining after microwave production has stopped. In this regard a microwave oven is much like an electric light that stops glowing when it is turned off. The Food and Drug Administration (FDA) has regulated the manufacture of microwave ovens since 1971. On the basis of current knowledge about microwave radiation, the Agency believes that ovens that meet the FDA standard and are used according to the manufacturer's instructions are safe for use.
Everyday Application- Arnulfo
Microwaves are not just used for cooking food, but for many other things as well. For example medicine, industry, science, consumer goods, and communication.
Medicine -In some cases microwaves can be used to treat health problems better than drugs. Microwaves are primarily used in medical cases as an alternative to surgery. For example an enlarged prostate. Instead of surgically removing the problematic organ, doctors can use microwaves to heat op the enlarging tissue of the prostate and in turn decreasing the size of the enlarged prostate.
Industry- Microwaves in this field are primarily used for clean up. They can be used to decrease air pollutants, sanitize hospital waste, enhance dry cleaning solvents, and clean up polluted soil.
Science- Scientists use microwaves to make a special conductor made of copper called chalcopyrite. Microwaves can add in the process of separating chemical compounds, thus allowing scientist to individually study each component of the compound.
- Communication- Microwaves are also in cellular phones, telephones, telegraphs, television, and satellites. They are useful in communication because they easily penetrate the earth's atmosphere. This comes in handy primarily for space-vehicle communication.
mobile phones use microwaves to connect to satellites and make calls.
microwaves are mostly used to cook food quickly, even though it always leaves the middle of my raviolis cold.
Satellites use microwaves to communicate with mobile phones and other satellites.
