A radioactive isotope of an element A radioisotope can be produced by placing material in a nuclear reactor and bombarding it with neutrons Radioisotopes are being used today as tracers in many areas of science and industry and are at present the most important peacetime contribution of nuclear energy
An unstable isotope of an element that eventually will undergo radioactive decay (i e , disintegration) Radioisotopes with special properties are produced routinely for use in medical treatment and diagnosis, industrial tracers, and for general research
A radioisotope is an isotope that has an unstable nucleus The nucleus emits a nuclear radiation to attain stability by a process called radioactive decay
A radioactive isotope An unstable isotope of an element that decays or disintegrates spontaneously, emitting radiation More that 1300 natural and artificial radioisotopes have been identified
An isotope which is radioactive Most natural isotopes lighter than lead are not radioactive Two important natural radioisotopes are carbon-14 and potassium-40
