Half life of technetium
WebFrom the radionuclides used for medical applications (shown in Table 12.3), the metastable technetium-99m (Tc-99m) is the most commonly used with a share of about 80%, since it optimally meets the previously mentioned requirements, having a gamma energy of 141 keV and a half-life of 6 hours. Last but not least, it is a generator product. WebTechnetium (Tc) is one of the two elements in the first 82 that have no stable isotopes (in fact, it is the lowest-numbered element that is exclusively radioactive); the other such element is promethium. The most stable radioisotopes are 98 Tc (half-life of 4.2 Ma), 97 Tc (half-life: 2.6 Ma) and 99 Tc (half-life: 211.1 ka).
