It has three long-lived radioactive isotopes but the most useful isotope has a short half-life that makes it useful for many medical tests. Radioactive Decay Questions and Answers.
List Of Elements By Stability Of Isotopes Wikiwand
Twenty-two isotopes of technetium are reported all of which are radioactive.
. The isotopes produced in the thorium fuel cycle are mostly not transuranic but some of them are still very dangerous such as 231 Pa which has a half-life of 32760 years and is a major contributor to the long-term radiotoxicity of spent nuclear fuel. The most stable isotope is astatine-210 which has a half-life of 81 hours. Get help with your Radioactive decay homework.
