Radio Waves. Radio waves are the waves having the longest wavelength in the electromagnetic spectrum. These waves are a kind of electromagnetic radiation and have a frequency from high 300 GHz to low as 3 kHz though somewhere it is defined as above 3 GHz as microwaves. At 300 GHz, the wavelength is 1 mm and at 3 kHz is 100 km.

The Higher Frequency Range of Radio Waves. HF, VHF, and UHF are the radio waves uses FM radio, communicate TV sound, public radio service, cellphones, and GPS. These groups regularly use "frequency modulation" (FM) to encode, or dazzle, a sound, or information signal onto the transporter wave. FM brings about excellent sign quality over AM ...

The area to be treated is then marked out. This is to guide the device delivering the radio waves over the whole area, evenly without overlapping. This device head transmits heat energy giving you a pleasant warming sensation without causing any discomforts. After the treatment, a soothing gel or lotion is applied on the designated area of the ...

3 kHz to 3 THz: Used as the designation for RF “radio frequency” waves. 3 THz to 380 THz: This is the infrared. It lies just outside the visible range and is therefore invisible to the naked eye, but can be sensed as heat. 380 THz to 790 THz: This is the portion of the EM spectrum visible as ordinary light to humans.

MO: Periodically come up to 10m or so depth submersion and receive/transmit signals in the LF/VLF bands. If more data is required, they surface and use satellite telemetry, UHF/SHF. If at depth, a very slow keyed signal at ELF~ULF can penetrate deep. The signal would be little more than code for 'surface for message'.

The electromagnetic and radio waves in the current environment are 10 17 times that of 10 years ago; minimal contact is no longer possible. 24-hours exposure at this level is equivalent to exposure to 1,600 X-rays. Using a mobile phone for 30 minutes every day can increase the risk of brain cancer by 40%.

Ionizing radio waves have the potential to cause sickness, burns, or cancer. Non-ionizing Non-ionizing electromagnetic waves don’t carry enough energy in their photons to ionize or break the atoms and cells. Radio waves which are emitted by mobile phones have lower energy radiation which can’t cause damage to our cells.

Radiation in Medicine: X-Rays. An x-ray is an image created on photographic film or electronically on a digital system to diagnose illnesses and injuries. During this type of medical imaging procedure, an x-ray machine is used to take pictures of the inside of the body. The x-rays pass through various parts of the body to produce images of ...

Normally, only a small number of cancer cells are active at any one time making cancer very difficult to treat in this way. Holt discovered that by exposing the body to 434 MHz radio waves, all the cancer cells were activated for a short period (about 20 minutes) and could thus be destroyed by subsequent low level X-Ray radiation.

Yet, radio waves are safe in comparison. RF waves, at very high levels, can heat body tissues. However, the energy levels given off by a cell phone is not as high and is unable to raise body temperature. Can radio waves hurt you?
Astronomical objects make all the waves that have normally happened. Falsely shaped radio waves are utilized in radio correspondence, radar, computer systems, broadcasting, diverse route frameworks, and various applications of radio waves. Radio waves are typically created by radio transmitters and can be gotten by radio recipients.

Radio-Wave Cancer Therapy. Dr. John Holt (retired) has had some startling success with radio-wave therapy treatment over more than 30 years. Yet his work had been largely ignored by cancer research organisations in Australia and elsewhere as he was using a treatment method not approved by the Australian Medical Association.
As high frequency radio frequency radiation, i.e., microwave radiation, penetrates the body, the exposed molecules move about and collide with one another causing friction and, thus, heat. This is known as the thermal effect. If the radiation is powerful enough, the tissue or skin will be heated or burned.
It is known, however, that exposure to non-ionizing radio frequency radiation may produce serious biological effects. As high frequency radio frequency radiation, i.e., microwave radiation, penetrates the body, the exposed molecules move about and collide with one another causing friction and, thus, heat. This is known as the thermal effect.
This can lead to burns and tissue damage. Although RF radiation does not cause cancer by damaging DNA in cells the way ionizing radiation does, there has been concern that some forms of non-ionizing radiation might have biological effects that could result in cancer in some circumstances. How are people exposed to RF radiation?
Microwave (MW) radiation is typically considered a subset of RF radiation, with frequencies from 300 megahertz (MHz) to 300 GHz. The table below shows the bands of RF and sub-RF fields. RF energy is generated by the acceleration of charge in circuits.
