What are the 10 uses of radioactivity?
In light of the nuclear tragedy in Japan, here are my top 10 uses for radiation that are not making electricity or blowing stuff up.
- Security.
- Space Exploration.
- Measurement.
- Sterilization/Irradiation.
- Carbon Dating.
- Promoting Genetic Mutation.

- Smoke Detectors.
What are 3 uses of isotopes?
Radioactive isotopes find uses in agriculture, food industry, pest control, archeology and medicine. Radiocarbon dating, which measures the age of carbon-bearing items, uses a radioactive isotope known as carbon-14. In medicine, gamma rays emitted by radioactive elements are used to detect tumors inside the human body.
What are the uses of radioisotopes 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.
What are the uses of radioactive isotopes 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. Small concentrations of short-lived isotopes can be detected whilst no residues remain in the environment.
What are radioactive isotopes give two examples?
The radiations emitted are in the form of alpha particles, beta particles and gamma rays. Common examples of radioactive isotopes are Arsenic−74, Iodine−131 and Cobalt−60.
What are two uses of radioactivity?
Radioactivity has several practical applications, including tracers, medical applications, dating once-living objects, and the preservation of food.
What is radioactivity and its uses?
Radioisotopes have found extensive use in diagnosis and therapy, and this has given rise to a rapidly growing field called nuclear medicine. These radioactive isotopes have proven particularly effective as tracers in certain diagnostic procedures.
Where are radioactive isotopes used?
Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
What are radioactive isotopes give two examples of radioactive isotopes?
Common examples of radioactive isotopes are Arsenic−74, Iodine−131 and Cobalt−60. (i) Cobalt−60 is used in the treatment of cancer cells. When the high−energy gamma radiations emitted by cobalt−60 isotopes are directed at the cancerous tumours , the cells are burnt.
What are the four uses of isotopes?
Uses of isotopes – 1) Isotopes of iodine are used for therapy in the treatment of thyrotoxicosis, cancer, etc. 2) Uranium, Radium, atomic number 84 isotopes are employed in atomic reactors. 3) atomic number 27 isotopes are used for irradiation of food products.
What are radioactive isotopes give two uses?
What are the harmful effects of radioactive isotopes?
Alpha particles – heavy but do not go over 20 cm. So if you don’t have an isotope close to you – you are totally safe.
What properties of radioactive isotopes make them useful?
What properties of radioactive isotopes make them useful? Radioactive isotopes give off energy that can be used to generate electricity all the radiation the isotopes five off allows them to be used as tracers in diagnosing and treating disease. The atomic mass of iron is 55.847 amu.
What is the most dangerous radioactive isotope?
Alpha Radiation. Alpha radiation is a type of energy released when certain radioactive elements decay or break down.
What are some advantages of radioactive isotopes?
(1) An organic solvent constituting the bulk of the mass,
