Question: What Is Radiation Explain?

What is radiation and where does it come from?

Most of it forms naturally from minerals.

These radioactive minerals are in the ground, soil, water, and even our bodies.

Background radiation can also come from outer space and the sun.

Other sources are man-made, such as x-rays, radiation therapy to treat cancer, and electrical power lines..

How can you protect yourself from radiation?

Staying inside will reduce your exposure to radiation.Close windows and doors.Take a shower or wipe exposed parts of your body with a damp cloth.Drink bottled water and eat food in sealed containers.

What is the biggest source of radiation?

The biggest source of natural background radiation is airborne radon, a radioactive gas that emanates from the ground. Radon and its isotopes, parent radionuclides, and decay products all contribute to an average inhaled dose of 1.26 mSv/a (millisievert per year).

How can you prevent cell phone radiation?

How to reduce exposure to cell phone radiationUse hands-free and text messages wherever possible. … Carry and keep your smartphone away from your body. … Avoid using your phone when it has a low signal. … Don’t sleep with your phone. … Be careful when streaming. … Don’t use “shielding” products.

How does radioactivity kill?

Ionizing radiation—the kind that minerals, atom bombs and nuclear reactors emit—does one main thing to the human body: it weakens and breaks up DNA, either damaging cells enough to kill them or causing them to mutate in ways that may eventually lead to cancer.

What is radioactivity and types?

Humans use radioactivity all the time, from medicine to food production. … There are different types of radioactivity depending on what particles or energy are released during the reaction. The three types are: alpha particles, beta particles, and gamma rays.

What is radiation in simple words?

From Wikipedia, the free encyclopedia. In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation such as radio waves, visible light, and x-rays.

What is radioactivity simple explanation?

Radioactivity is the spontaneous emission of radiation in the form of particles or high energy photons resulting from a nuclear reaction. … A substance that contains unstable atomic nuclei is considered to be radioactive. Radioactive decay is a random or stochastic process that occurs at the level of individual atoms.

What is radiation made up of?

Radiation is energy given off by matter in the form of rays or high-speed particles. All matter is composed of atoms. Atoms are made up of various parts; the nucleus contains minute particles called protons and neutrons, and the atom’s outer shell contains other particles called electrons.

Is radiotherapy worse than chemotherapy?

Radiation therapy involves giving high doses of radiation beams directly into a tumor. The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.

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 is radiation and how it works?

Radiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die. Nearby normal cells can also be affected by radiation, but most recover and go back to working the way they should.

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 is radiation done?

Radiation therapy can be given in 3 ways: External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. … Internal radiation: Internal radiation is also called brachytherapy.
