What are the natural sources of radiation?
The composition of the earth’s crust is a major source of natural radiation.
The main contributors are natural deposits of uranium, potassium and thorium which, in the process of natural decay, release small amounts of ionizing radiation..
What is radiation used for in everyday life?
Radiation & Me Many uses of radiation help to ensure the high quality and safety of our daily lives. Smoke detectors to warn us of fire, x-ray machines to detect weapons or other devices in luggage and cargo, and certain types of imaging to look for diseases are all application of radiation for the benefit of society.
What are some examples of radioactivity?
One example of a radioactive substance is uranium. In nuclear power plants, uranium is used to produce electricity. When radioactive substances like uranium produce radiation, they also create a lot of heat.
What things use radiation?

What is radiation in your own words?
noun. 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 are the 3 types of radiation?
The three most common types of radiation are alpha particles, beta particles, and gamma rays.
What type of radiation is used in medicine?
Medical radiation. X-rays, gamma rays, and other forms of ionizing radiation are used to diagnose and treat some medical conditions. This can be in the form of radiation that penetrates from outside the body, or radioactive particles that are swallowed or inserted into the body.
What are benefits of radiation?
This allows the cancer cells to be killed or reduced in number whilst protecting the majority of other organs and tissues in the body. Radiation therapy contributes to 40% of all cancer cures world-wide as well as relieving symptoms, such as pain, and improving the quality of life for many others.

What is radiation in simple words?
Radiation. 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 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 4 uses of radiation?
Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity. In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.
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 is radiation used in hospitals?
MEDICINE. Hospitals use radiation in a wide range of ways. X-Ray, CT, and PET machines use X-ray (X-ray and CT) and Gamma radiation (PET) to produce detailed images of the human body, which provide valuable diagnostic information for doctors and their patients.
