The radioactive elements uranium and plutonium are used in the generation of electricity in nuclear power plants. Small radiactive sources of particles are used in many home smoke detectors. These elements are also used in the production of nuclear weapons.

Which radioactive elements can be used in medicine?

ISOTOPS COMMONLY USED IN MEDICINE: There are about 20 radioactive isotopes used in medicine. Each isotope has its own use in this field. Some of them are: Chromium-51, cobalt 60, Erbium 169, Iodine-125, Iridium-192, Sodium-24, Xenon-133, Selenium-75, Strontium-89, Phosphorus-32 etc.

Which of the following elements are radioactive?

Alpha Radiation For example, uranium and thorium are two radioactive elements found naturally in the Earths crust. Over billions of years, these two elements slowly change form and produce decay products such as radium and radon. During this process, energy is released. One form of this energy is alpha radiation.

What is the most useful radioactive element?

Polonium Polonium. Because it is a naturally-occurring element that releases a huge amount of energy, many sources cite polonium as the most radioactive element.

Which of the following element is radioactive in nature?

Explanation: Thorium is one of only two significantly radioactive elements that still occur naturally in large quantities as a primordial element (the other being uranium). Thorium is weakly radioactive: all of its known isotopes are unstable.

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.

How radioactivity is used in hospitals?

For therapy, radioactive materials are used to kill cancerous tissue, shrink a tumor or reduce pain. Therapeutic nuclear medicine uses high doses of radiation from materials that are injected into or ingested by the patient. For example, radioactive iodine can destroy or shrink a diseased thyroid.

Which element is named on the name of Earth?

Tellurium Tellurium is named after the Latin word tellus, meaning earth.

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.

Is radiation good or bad?

Although it can be destructive, radioactivity can also be beneficial, especially when it comes to medical tests and certain medical treatments. Not only can radiation find tumors within the body, it can also destroy them or slow their growth.

How is radioactivity used today?

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 are 5 sources of man made radiation?
