What are the 7 types of electromagnetic radiation?
This range is known as the electromagnetic spectrum.
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency.
The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays..
What types of radiation are harmful?
Alpha particles are the most harmful internal hazard as compared with gamma rays and beta particles. Radioactive materials that emit alpha and beta particles are most harmful when swallowed, inhaled, absorbed, or injected. Gamma rays are the most harmful external hazard.
How do you identify radiation type?
To determine the type of radiation (alpha, beta or gamma), first determine the background count rate, then the source count rate with no absorber. Next, place a sheet of paper between the source and the monitor. If the counts are significantly reduced, the source emits alpha particles.
What are the 2 types of radiation?
There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.
What household items give off radiation?
10 surprising household items that emit radiationLow levels of radiation. … Cell phones, tablets, computers. … Smart meters. … Wi-Fi routers, Bluetooth transmitters. … Microwaves. … Cigarettes. … Television. … Antiques: Furniture, jewelry, silverware, etc.
What is the least dangerous radiation?
Ionizing radiation comes in three flavors: alpha particles, beta particles and gamma rays. Alpha particles are the least dangerous in terms of external exposure. Each particle contains a pair of neutrons and a pair of protons.
How many types of radiation are there?
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. The first is an alpha particle.
What type of radiation is light?
electromagnetic radiationRadio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. 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.
What is the most dangerous radiation?
Gamma raysGamma rays are the most harmful external hazard. Beta particles can partially penetrate skin, causing “beta burns”. Alpha particles cannot penetrate intact skin. Gamma and x-rays can pass through a person damaging cells in their path.
What is radiation examples?
Examples of Radiation Examples include: A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles. Uranium-238 decaying into Thorium-234 emits radiation in the form of alpha particles.
What materials can block radiation?
Non-lead shielding materials are manufactured with additives and binders mixed with attenuating heavy metals that fall into the same category of materials as lead that also absorb or block radiation. These metals may include tin (Sn), antimony (Sb), tungsten (W) bismuth (Bi) or other elements.
What are the 3 main types of radiation?
The three most common types of radiation are alpha particles, beta particles, and gamma rays.
What are the 5 types of radiation?
Radiationelectromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)particle radiation, such as alpha radiation (α), beta radiation (β), and neutron radiation (particles of non-zero rest energy)More items…
What is radiation in simple words?
The energy radiated or transmitted in the form of rays, waves, or particles. A stream of particles or electromagnetic waves that is emitted by the atoms and molecules of a radioactive substance as a result of nuclear decay.
What is the most common type of radiation?
There are many types of radiation and radioactive emissions. The information we are providing discusses only the four most common types: alpha particles, beta particles, gamma rays, and x rays.
Which type of radiation has a +2 charge?
Alpha DecayAlpha Decay This type of radiation has a positive charge (due to the presence of two protons). An alpha particle is sometimes represented using the chemical symbol He2+, because it has the same structure as a helium atom missing its two electrons—hence the overall charge of +2.
Which is the most Ionising radiation?
Gamma radiationBeta radiation is more penetrating than alpha radiation. It can pass through the skin, but it is absorbed by a few centimetres of body tissue or a few millimetres of aluminium. Gamma radiation is the most penetrating of the three radiations.
What is the shortest wavelength of radiation?
violetRed has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Ultraviolet (UV) light—is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 .
