To understand Radio Frequency Microwaves first we must understand what microwaves are and how is RF related to it. Microwaves are generated from electrical and magnetism reactions and as a result generating certain radiation and waves known as the microwaves. The frequency at which these waves operate is between 300MHz to 300GHz and in this range, it includes both bands of Ultra High Frequency and Extremely High Frequency.
The wavelengths
They have the wavelength in the range of 1mm up to 1m. The microwaves are relatively small as compared to the previous technology waves. They travel in a straight line therefore they can’t penetrate through different materials or objects standing in their path. They cover up to 40 miles or 64 km only in a straight path.
The General Radio Frequency ranges from around 20kHz to 300GHz. RF microwaves are the ones that are included in the microwave spectrum which is around 300MHz to 300GHz and since they are in the category of microwaves the lower frequencies than 300MHz are excepted. They usually occur in the lower limits of the infrared frequencies.
Various industries use this technology such as in the medical field the use of RF treatment goes over to about 75 years and they use this to perform invasive surgeries and treat medical conditions like sleep apnea and cancer. They are also used in MRI to make the images of the human body and used to reduce fat from it by using lipolysis.
RF Microwave uses
Nowadays in communication, this technology is widely used such as in mobiles we have Bluetooth and GPS receiver. They are used inside television and computer in the form of various IC, CMOS and RF chips. Aside from these the uses of RF Microwaves are extending daily and now they are being used in our daily routines.
The effects of RF Waves on the human body
As they are being vastly used because of their wireless properties still they impose some effects on the human body due to the radiation they emit. These radiations result in putting biological effects on the human body. It causes the heating of tissues inside a human body due to the thermal effects produced by RF radiations. These effects normally occur when exposing to high frequencies of these waves because the body can’t resist those high levels of radiation. Body parts that are most vulnerable to these radiations are eyes and testes because the flow of blood in them is minimum than the other parts of the body.
Many standards are being introduced for the safety of workers and employees under the radiation hazards of these waves. Some of the companies introducing such standards are the Environmental Protection Agency, World Health Organization and FDA. They have started new research programs and other health safety projects like the National Toxicology Program and RF Biological effects program. These programs set up the standards and do research related to the harmful effects they have on human health and how to minimalize them.
