Quick answer: What Is Radiation In Simple Words?

What is the definition of radiation for kids?

Radiation is energy that moves from one place to another.

Light, sound, heat, and X-rays are examples of radiation.

The different kinds of radiation fall into a few general categories: electromagnetic radiation, mechanical radiation, nuclear radiation, and cosmic rays..

What are 4 examples of radiation?

Here are some examples of different types of radiation:ultraviolet light from the sun.heat from a stove burner.visible light from a candle.x-rays from an x-ray machine.alpha particles emitted from the radioactive decay of uranium.sound waves from your stereo.microwaves from a microwave oven.More items…•

What are the 2 types of radiation?

This includes:electromagnetic 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 are the natural sources of radiation?

The Earth itself is a source of terrestrial radiation. Radioactive materials (including uranium, thorium, and radium) exist naturally in soil and rock. Essentially all air contains radon , which is responsible for most of the dose that Americans receive each year from natural background sources.

Who discovered the radiation?

Henri BecquerelThough it was Henri Becquerel that discovered radioactivity, it was Marie Curie who coined the term. Using a device invented by her husband and his brother, that measured extremely low electrical currents, Curie was able to note that uranium electrified the air around it.

What is radiation easy definition?

Radiation is the process of sending off energy in the form of light, heat, x-rays or nuclear particles. An example of radiation are the energy waves off of a nuclear bomb.

What is another word for radiation?


What is the most dangerous type of radiation?

Gamma raysGamma rays are often considered the most dangerous type of radiation to living matter. Unlike alpha and beta particles, which are charged particles, gamma rays are instead forms of energy.

Is a fire an example of radiation?

Heat passes through the empty space until it reaches your hand. That’s radiation! A fire is another example of radiation. Even YOU are an example.

What is radiation caused by?

Radiation is the energy released from atoms as either a wave or a tiny particle of matter. Radiation sickness is caused by exposure to a high dose of radiation, such as a high dose of radiation received during an industrial accident.

Here are some words that are associated with radiation: energy, irradiation, radioactivity, neutron, cosmic ray, alpha particle, nuclear fission, particles, ionizing radiation, radioactive, radiotherapy, electromagnetic radiation, electromagnetic spectrum, physics, nuclear fusion, gamma ray, radon, positron, cancer, …

Which is the best example of radiation?

A good example would be heating a tin can of water using a Bunsen burner. Initially the flame produces radiation which heats the tin can. The tin can then transfers heat to the water through conduction. The hot water then rises to the top, in the convection process.

Why is radiation so dangerous?

Radiation damages the cells that make up the human body. Low levels of radiation are not dangerous, but medium levels can lead to sickness, headaches, vomiting and a fever. High levels can kill you by causing damage to your internal organs. … Exposure to radiation over a long time can cause cancer.

What are the 3 types of radiation?

The three most common types of radiation are alpha particles, beta particles, and gamma rays.

What are the 7 types of radiation?

The different types of electromagnetic radiation shown in the electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet radiation, X-rays, and gamma rays.

What is radiation and examples?

Examples of Radiation Radiation includes emanation of any portion of the electromagnetic spectrum, plus it includes the release of particles. 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.

How does radiation affect a child?

When given equal radiation doses, the risks for children and adolescents are greater than for adults. Children grow quickly, and their cells are more sensitive to radiation. … As adults age, radiation exposure becomes less of a concern. The body tissues of older patients are less sensitive to the effects of radiation.

Is gravity a form of radiation?

Gravitational Radiation. Gravitational Radiation is to gravity what light is to electromagnetism. It is produced when massive bodies accelerate.
