how many types of radiation are there?
250253
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects.

UV radiation is a form of electromagnetic radiation that mainly comes from the sun. There are three types of UV rays: UVA, UVB and UVC rays. UVA rays are the weakest, but they cause skin cells to age faster. UVB rays are a little stronger, and can cause sunburns and skin cancer.

There are three types of radiation: alpha particles, beta particles and gamma rays. Beta particles can be blocked by a sheet of aluminum, but gamma rays require several inches of lead, concrete or steel to be stopped.

X-rays are high-frequency, and thus high-energy, electromagnetic radiation. They have wavelengths ranging from 0.01 to 10 nanometres, and thus frequencies from 3×1019 to 3×1016 Hz.
254016
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
85699
Radiation is an electromagnetic wave that has no charge and no mass. X-rays and gamma-rays can be characterized by frequency, wavelength, and energy.
874435
Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light. Each photon contains a certain amount of energy. The different types of radiation are defined by the the amount of energy found in the photons.

X-rays, gamma rays, and charged particles are types of radiation used for cancer treatment.

Some examples of radiation include sunlight, radio waves, x-rays, heat, alpha, beta, gamma ionizing radiation, and infrared, just to name a few. Not all of these types of radiation are harmful, in fact, in moderation, most radiation will not pose a health risk.

Of the three main types of radiation given off during radioactive decay, two are particles and one is energy; scientists call them alpha, beta and gamma after the first three letters of the Greek alphabet. Alpha and beta particles consist of matter, and gamma rays are bursts of energy.

Answer and Explanation: A flame emits both visible light and infrared radiation. There are seven different types of electromagnetic radiation, and they are gamma rays, x-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves.

2.  X-radiations (or x-rays) is a form of electromagnetic radiations. Most x-rays have a wavelength of 0.01-10 nanometeres, corresponding frequencies in the range of 30 petahertz(3X10¹⁶ Hz) to 30 exahertz(3*X10¹⁹Hz) and energies in the range of 100eV to 100 keV.

Though the sun emits all of the different kinds of electromagnetic radiation, 99% of its rays are in the form of visible light, ultraviolet rays, and infrared rays (also known as heat). Man-made lamps can also emit UV radiation, and are often used for experimental purposes.

From lowest energy to highest energy (red to blue) there are radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays. Each of them have their uses and, at the high energy end, they also have their dangers.
710396
Gamma radiation or gamma rays are high-energy photons that are emitted by radioactive decay of atomic nuclei. Gamma radiation is very high-energy form of ionizing radiation, with the shortest wavelength.
379256
The Electromagnetic spectrum consists of the follwing types of radiation: radio waves, microwaves, infrared, visible, ultraviolet, X-rays, gamma-rays. Gamma-rays have the most energy and are the most penetrating, while radio waves have the lowest energy and are the least penetrating.
