How does radiation happen?
Radiation is energy that travels in the form of waves (electromagnetic radiation) or high-speed particles (particulate radiation).
Particulate radiation happens when an unstable (or radioactive) atom disintegrates.
Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves..
How was radiation discovered?
In 1896, Henri Becquerel found that rays emanating from certain minerals penetrated black paper and caused fogging of an unexposed photographic plate. His doctoral student Marie Curie discovered that only certain chemical elements gave off these rays of energy. She named this behavior radioactivity.
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.
Who found out radioactivity?
Henri BecquerelThe Discovery of Radioactivity. In 1896 Henri Becquerel was using naturally fluorescent minerals to study the properties of x-rays, which had been discovered in 1895 by Wilhelm Roentgen.
What are 5 examples of radiation?
Radiation Examplesultraviolet 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.electromagnetic radiation from your cell phone.More items…•
What is man made radiation?
Man-Made Radiation. … Radiation used in medical applications is the largest source of man-made radiation that people in the industrialized countries are exposed to. The majority of this exposure is from diagnostic X-rays , which are used by physicians to determine the extent of disease or physical injury.
What is the most radioactive country?
Japan1 Fukushima, Japan Is The Most Radioactive Place On Earth Even though it’s been nine years, it doesn’t mean the disaster is behind us. The Japanese government is actually thinking about dumping radioactive water in the Pacific.
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.
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 radiation hurt?
How does radiation harm the body? … As radioactive material decays, or breaks down, the energy released into the environment has two ways of harming a body that is exposed to it, Higley said. It can directly kill cells, or it can cause mutations to DNA. If those mutations are not repaired, the cell may turn cancerous.
Can radiation be passed from person to person?
Radiation cannot be spread from person to person. Small quantities of radioactive materials occur naturally in the air, drinking water, food and our own bodies. People also can come into contact with radiation through medical procedures, such as X-rays and some cancer treatments.
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.
What is the largest source of man made radiation?
By far, the most significant source of man-made radiation exposure to the public is from medical procedures, such as diagnostic X-rays, nuclear medicine, and radiation therapy.
Is radiation man made?
Radioactivity, a Natural or Man-Made Phenomenon. The decay of unstable atoms releases radiation, a phenomenon called radioactivity. As unstable atoms exist in all matter, we are surrounded by natural radiation. Radiation can also come from man-made sources, through military, medical or industrial applications.
How does radiation 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 does radiation feel like?
Initial symptoms include nausea, vomiting, headache and diarrhoea. These symptoms can start within minutes or days after the exposure. People who have been exposed to high doses can also have skin damage ranging from itching to burns, blisters and ulcers. They may also have temporary hair loss.
Who was the first person to die of radiation?

What are the 3 types of radiation?
The three most common types of radiation are alpha particles, beta particles, and gamma rays.
