Transuranium elements that have half-life more than 1000 year have to be determined using table 11-2 as the information source. Concept Introduction: Radioactive nuclides undergo disintegration by emission of radiation. All the radioactive nuclide do not undergo the decay at a same rate. Some decay rapidly and others decay very slowly. The nuclear stability can be quantitatively expressed by using the half-life. Radioactive decay happens naturally. This can also be done artificially in the laboratory by means of bombardment reaction. Bombardment reaction produces synthetic nuclides. These synthetic radionuclides are known as transuranium elements. This is because they occur after uranium. The atomic number of transuranium elements is from 93 to 118.
