The clinical use of Isotopes dates back in the 1930s, although they were widely used for research after World War II. Isotopes are different forms of a single element. Gamma sterilisation is used for medical supplies, some bulk commodities and, increasingly, for food preservation. Among elements with a known stable isotope, only tellurium and rhenium similarly occur with a stable … 5. contd. Give any two uses of isotopes. These are unstable isotopes of the elements which are undergoing nuclear transmutations by themselves and are emitting radiations. To date we use roughly 40 activation product radioisotopes and also 5 isotopes that are products of fission in reactors. Uses of Radioactive Isotopes - Medicine. Stable isotopes are non-radioactive forms of atoms. C 12 being the most abundant of the three isotopes and this element being the backbone of life on Earth, its uses are endless. Key Terms. 5. A number of medium-size cyclotrons producing major isotopes for medical applications are owned and operated by private sector enterprises for their exclusive uses. isotopes of magnesium: 24Mg, 25Mg, and 26Mg. For example, the element hydrogen exists in nature as the isotopes hydrogen, deuterium and tritium. The hydrogen isotope is the most abundant type on Earth and possesses zero neutrons per atom, whereas a deuterium atom contains one neutron, and a tritium atom has two. Radionuclides also have important uses. previous Industry uses radioisotopes in a variety of ways to improve productivity and gain information that cannot be obtained in any other way. This is because chlorine contains two different isotopes, chlorine-35 and chlorine-37. isotopes of lithium: 6Li and 7Li. β-rays can be used for material thicknesses up to about 1.5 mm of steel.
