What are the four radioactive isotopes?

There are four types of radiation given off by radioactive atoms: Alpha particles. Beta particles. Gamma rays.
…
When uranium-238 decays it produces several isotopes of:

Thorium.
Radium.
Radon.
Bismuth.

What are isotopes Give two uses of isotopes?

1) Isotopes of iodine are used for radiotherapy in treatment of hyperthyroidism cancer etc. 2) Uranium Radium Polonium isotopes are used in atomic reactors. 3) Cobalt isotopes are used for irradiation of food products.

What are two isotopes of carbon?

Carbon occurs naturally in three isotopes: carbon 12 which has 6 neutrons (plus 6 protons equals 12) carbon 13 which has 7 neutrons and carbon 14 which has 8 neutrons. Every element has its own number of isotopes.

What are radioactive isotopes Class 9?

A radioactive isotope also known as a radioisotope radionuclide or radioactive nuclide is any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha beta and gamma rays.

What is meant by radioactivity give two example?

For example a light bulb may emit radiation in the forms of heat and light yet it is not radioactive. 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 are isotopes Give two uses of isotopes Class 9?

Application of Isotopes

1)An isotope Uranium is used as a fuel in nuclear reactor. 2)An isotope of cobalt is used in treatment of cancer. 3)An isotope of iodine is used in treatment of goitre.

How are radioisotopes used in agriculture?

Radioisotopes are used as a research tool to develop new strains of agricultural crops that are drought and disease resistant are of higher quality have shorter growing time and produce a higher yield. … Ionizing radiation is very useful for preservation of agricultural and food products.

What are the various uses of radioactivity in healthcare?

For example technetium-99m is used to diagnose bone heart or other organ problems. Radioactive iodine is used in imaging the thyroid gland. For therapy radioactive materials are used to kill cancerous tissue shrink a tumor or reduce pain. There are three main types of therapy in nuclear medicine.

How are isotopes used in earth science?

They are used to study different ecological biological chemical and geological systems and understand their dynamics and interactions. Environmental applications of these isotopes include tracing pollutant migration assessing and predicting climatic changes and planning for water management.

What is used for compound containing radioactive isotope?

When the atomic nucleus of an isotope is unstable compounds containing this isotope are radioactive. … The principle behind the use of radioactive tracers is that an atom in a chemical compound is replaced by another atom of the same chemical element.

What are isotopes write any 3 uses of isotopes?

some radioactive isotopes are used to measure atomic masses of elements and study their properties. it is used to produce nuclear energy in many places. it is used to determine the age of minerals.it can even determine the composition of minerals. example-we know carbon-14 can determine fossils age.

What are isotopes write one example and two application of isotopes?

1)An isotope Uranium is used as a fuel in nuclear reactor. 2)An isotope of cobalt is used in treatment of cancer. 3)An isotope of iodine is used in treatment of goitre.

What are two radioactive isotopes of oxygen?

There are several radioactive isotopes of oxygen but two examples would be oxygen-13 and oxygen-14.

Which isotope of carbon is radioactive?

carbon-14

carbon-14 the longest-lived radioactive isotope of carbon whose decay allows the accurate dating of archaeological artifacts. The carbon-14 nucleus has six protons and eight neutrons for an atomic mass of 14.

What are isotopes use carbon as an example?

Isotopes of an element share the same number of protons but have different numbers of neutrons. Let’s use carbon as an example. There are three isotopes of carbon found in nature – carbon-12 carbon-13 and carbon-14. All three have six protons but their neutron numbers – 6 7 and 8 respectively – all differ.

How are radioisotopes used in scientific research and medicine?

Radioisotopes are also used in medical treatment. For example cancers can be bombarded with radiation produced by radioisotopes to kill the cancer cells. Radioisotopes can also be used to sterilize medical instruments. They’re even used in drug research helping us discover new treatments for all kinds of diseases.

What is radioactive element with example?

For example uranium and thorium are two radioactive elements found naturally in the Earth’s 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 does radioactive mean in science?

As its name implies radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that for some reason is unstable it “wants” to give up some energy in order to shift to a more stable configuration.

What are the 3 types of radiation?

The three most common types of radiation are alpha particles beta particles and gamma rays.

What are the uses of isotopes Class 8?

Isotopes are the atoms in which the number of neutrons differs and the number of protons is the same. From the above definition of atomic mass and the atomic number we can conclude that isotopes are those elements having the same atomic number and different mass number.

How radioactive isotopes are used in food preservation?

Food irradiation is the process of exposing foodstuffs to gamma rays to kill bacteria that can cause food-borne disease and to increase shelf-life. … In addition to inhibiting spoilage irradiation can delay ripening of fruits and vegetables to give them greater shelf-life.

What is radiation used for?

Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells. Radiation therapy most often uses X-rays but protons or other types of energy also can be used. The term “radiation therapy” most often refers to external beam radiation therapy.

How do radioactive isotopes differ from isotopes?

Basic principles. Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. … Radioactive (unstable) isotopes have nuclei that spontaneously decay over time to form other isotopes.

How are radioactive materials essential in scientific research?

Radioactive materials are used to help some researchers create and test new medicines technologies and procedures that benefit plants animals and people. Research laboratories must follow strict rules to order store use and dispose of radioactive material.

What is radiation as used in geology?

Radiation is the emission of energy in the form of waves or particles that travels through space or impact materials with effects that depend on the energy of the emission. That allows classifying radiation in the electromagnetic spectrum as either ionizing or non-ionizing.

How is nuclear radiation used in industry?

Radioisotopes are used by manufacturers as tracers to monitor fluid flow and filtration detect leaks and gauge engine wear and corrosion of process equipment. … Radiotracers are also used in the oil and gas industry to help determine the extent of oil fields.
