uses radioactive isotopes

All isotopes of a substance have the same chemical properties and behave in an identical manner. The advantage of a radioisotope is that its position can be detected very easily by the radiation which it emits. It has wide applications in various fields lik..

Radioactive elements are those, which emit invisible radiations of their own accord. This is called radioactivity. Some typical examples of radioactive elements are uranium, thorium, plutonium, polonium etc. Radiations emitted by radioactive elements consist..

All radioactive decays follow first order kinetics. Therefore, the half-life of a radioactive element is independent of the amount of sample. With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or in an artefact, the age of the..

Isotopes are the different forms of the same element, which have the same atomic number but different mass numbers. The isotopes of hydrogen are protium, deuterium and tritium with mass number 1, 2 and 3 respectively. The relative abundance of three isotopes in nature..

Radioactive Waste - Waste products from nuclear power stations etc. are becoming a serious problem. They should be put where the radiation can do no harm. Unfortunately, there is no way of stopping a radioactive nucleus from emitting radiation. Nuclear energy has some advantages..

Tungsten carbide (WC) is used for making cutting drilling tools. Silicon carbide (SiC) is used as an abrasive and refractory material. SiC is also called carborundum. Boron carbide (B 4 C) is harder than silicon carbide, and is used as an abrasive and as a shield again..

(i) Most of the sulphur produced is used for the manufacture of sulphuric acid and other industrially important sulphur compounds. (ii) Sulphur is used to prepare large number of medicines (Sulpha drugs) and can be used as ointment for curing skin diseases. (iii) It is..

Radioisotopes are frequently used as tracers or tagged atoms in various fields. In tracer technique, a radioactive isotope is added to the reactants and its movement is studied by measuring radioactivity in different par..
