What Do You Know About the Electromagnetic Radiation Spectrum?

Radiation is something most people have heard of, usually in the context of the dangers it can cause. Many associate radiation with the sun, which can cause minor sunburn or even increase your chances of skin cancer.

However, radiation actually takes many forms, not all of which are dangerous. Among the different types of electromagnetic waves, radiation is a form of energy that can be found all around us. The human body itself emits a form of radiation, which is emitted constantly as ambient heat, also known as body heat.

The Electromagnetic Radiation Spectrum Has Seven Types

So, what is the electromagnetic radiation spectrum, also known as the electromagnetic spectrum? The electromagnetic radiation spectrum is the range of all types of radiation, which are waves of energy that travel through space at the speed of light. This spectrum encompasses a wide variety of radiation types, each with different wavelengths and frequencies. To understand its role in therapy, let’s consider the seven types of radiation.

• Radio Waves: This part of the spectrum has the longest wavelengths and lowest frequencies. They are used for communication, such as broadcasting radio and television signals, as well as in radar and satellite transmissions.
• Microwaves: With shorter wavelengths than radio waves, microwaves are used in cooking (microwave ovens), as well as in certain communication technologies and radar.
• Infrared Radiation: Infrared waves are primarily associated with heat. They are used in thermal imaging, remote controls, and some communication devices.
• Visible Light: This visible part of the spectrum is visible to the human eye. It includes all the colors we see, from red (longest wavelength) to violet (shortest wavelength).
• Ultraviolet (UV) Radiation: UV radiation has shorter wavelengths than visible parts of light and is responsible for causing sunburns. It is used in sterilization and fluorescent lighting.
• X-Rays: These have even shorter wavelengths and are used in medical imaging to view the inside of the body, as well as in security scanners.
• Gamma Rays: With the shortest wavelengths and highest frequencies, gamma rays are produced by radioactive atoms and in nuclear reactions. They are used in cancer treatment and are also emitted by cosmic phenomena.

Each Type of Radiation is Broken Down Into Frequency, Wavelength, and Energy

• Frequency is measured in cycles per second or Hertz.
• Wavelength is measured in meters.
• Energy is measured in electron volts.

Now that you know what the electromagnetic spectrum is, you should be able to understand the primary difference between the opposite spectrums of electromagnetic radiation. This is measured by wavelength, frequency, and the amount of energy given off. The wavelength of radiation given off by radio waves is longer, while the wavelength given off by gamma rays is much shorter.

The frequency of radiation given off by radio waves is lower, while the frequency given off by gamma rays is much higher. The energy given off by radio waves is lower, while the energy given off by gamma rays is much higher.

Why Do Some Parts of the Electromagnetic Radiation Spectrum Give Off Light?

When looking at the electromagnetic radiation spectrum, it is important to note that some areas of the spectrum give off radiation in the form of light, also known as photons. These photons, which are a stream of mass-less particles, travel in a wave-like pattern at the speed of light. Photons are not in radio waves or microwaves, but they are found in infrared light through gamma rays.

The various types of electromagnetic waves range from radio waves, which produce the lowest energy and longest wavelength, to gamma rays, which have the highest energy and shortest wavelength. Visible light, which is what the human body can see freely, lies in the middle of the electromagnetic spectrum. Radio waves are made up of the lowest amount of energy, while gamma rays are made up of the highest amount of energy.

Three Types of Infrared (IR) Radiation

Infrared spans a broad temperature range and exhibits diverse heat characteristics across frequencies. For this reason, it is categorized into three types of electromagnetic waves based on its distinct physical properties:

• Near-infrared radiation (NIR): NIR spans 700nm to 1,300nm (0.7 to 1.3 microns) with a frequency of approximately 215 THz to 400 THz.
• Mid-infrared radiation (MIR): This band spans 1,300 nm to 3,000 nm (1.3 to 3 microns), with frequencies from 20 THz to 215 THz.
• Far infrared radiation (FIR): Akin to microwaves, FIR spans 3,000 nm to 1 mm (3 to 1,000 microns), with frequencies from 0.3 THz to 20 THz.

Among the infrared radiation types, only NIR transfers in the form of heat energy, while FIR transfers in the form of photons, not heat, which is what makes FIR unique, differentiating itself from conventional NIR technology that relies on heat energy. The thermoreceptors within human skin cells read FIR as radiant heat.

Far Infrared vs. Infrared

The term infrared radiation refers to all three types of infrared radiation, while far infrared radiation is a subset form of infrared radiation, which is most commonly used for biological effects.

Far-infrared therapy harnesses far-infrared radiation, a segment of the electromagnetic spectrum. Although invisible to the human eye, infrared light can be felt as heat. “Far” denotes its position on the light spectrum.

These light waves can have a warming effect on your body, without heating the surrounding air. They can penetrate the deeper layers of body tissue, making them the preferred choice for therapeutic applications.

Thanks to the advancements in science and technology, it is possible to utilize this radiation as a form of treatment for certain medical conditions and ailments. The radiation is used to stimulate cells and tissues because it is safe and effective for use on human (and animal) cells and tissues. Unlike higher forms of radiation, far infrared photons don’t permanently alter or damage the cells. That is why the therapeutic uses of FIR radiation are becoming more promising in the medical community.

Non-ionizing vs. Ionizing Types of Radiation

As mentioned, the spectrum of electromagnetic radiation is made up of different degrees of radiation, and some of that radiation can result in biological changes if overexposed to them.

• Non-ionizing forms of radiation consist of non-thermal, thermal, and some of the optical spectrum within the electromagnetic spectrum.
• The lower the energy is, the less dangerous it becomes to the body.
• For example, radiation within the optical view of the spectrum, like a heat lamp, can be therapeutic. While a tanning bed can also be therapeutic, overexposure can become dangerous.
• With a heat lamp giving off infrared radiation, the human eye can see the energy in the form of light and feel it in the form of heat. The wavelength only penetrates into the topmost layer of the body and excites the electrons. This is referred to as non-ionizing.
• Meanwhile, a tanning bed can offer similar therapeutic benefits, although the energy is higher. This can make it more dangerous and is known as ionizing.
• A tanning bed uses ultraviolet radiation to mimic that of the sun. If overexposed to this form of radiation, the body will become damaged or burned.
• Ultraviolet rays through gamma rays cannot be seen by the human eye, but they can damage DNA and other cells within the body. This end of the electromagnetic spectrum is the most common form of radiation.
• Most of us are taught to fear it as too much sun can damage our cells, resulting in skin cancer.
• Similarly, the higher the amount of radiation from a medical scan (x-ray to PET scan or MRI), the more dangerous it can be for the cells of the body.
