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.

What is radiation and why is it important?
Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells.
What is an example of useful radiation?
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.
Is radiation good for body?
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.
How is radiation useful in medicine?
Nuclear medicine procedures help detect and treat diseases by using a small amount of radioactive material, called a radiopharmaceutical. Some radiopharmaceuticals are used with imaging equipment to detect diseases. ... Radiopharmaceuticals are also used to treat disease by shrinking tumors and killing cancerous cells.
Why is radiation useful to US Class 7?
All hot bodies emit heat by the process of radiation. Radiation of heat does not require a medium. Sunlight comes to the earth because of radiation as there is no medium present between the atmosphere of the earth and the sun. ... We get warmth from the room heater because of radiation.
How is radiation used in our everyday lives?
Every day, we use Ionizing radiation to help us live healthy lives. Ionizing radiation is found in smoke detectors, used to disinfect medical instruments and blood, and to perform many other tasks in our daily lives. It is also a byproduct of nuclear power generation.
What is the meaning and uses of radiation?
: a type of dangerous and powerful energy that is produced by radioactive substances and nuclear reactions. : the use of controlled amounts of radiation for the treatment of diseases (such as cancer) : energy that comes from a source in the form of waves or rays you cannot see.
What is an important source of radiation?
Exposure from terrestrial 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 are 5 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.
What do radiation means?
Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.
Why is radiation useful to US short answer?
Answer: 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 device in luggage and cargo, and certain types of imaging to look for diseases are all application of radiation for the benefit of society.
What is radiation in simple words?
Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. Light, radio, and microwaves are types of radiation that are called nonionizing. ... Gamma radiation and x rays are examples of electromagnetic radiation.
What are three facts about radiation?
People emit more radiation than their cell phones do. Most of the radiation people are exposed to daily is not harmful because it is non-ionizing. Inside the Chernobyl reactors grows a type of fungus that actually thrives on radiation. A toy released in the 1950s had uranium samples in it.
What is radiation explain with example?
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. ... The shooting forth of anything from a point or surface, like the diverging rays of light; as, the radiation of heat.
