List of radioactive nuclides by half-life

This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10โˆ’19 and 10โˆ’10 seconds.[1]
