Radioactive half-lives range from tiny fractions of a second to longer than the universe's age

Nearly 54 Orders Of Magnitude

Known radioactive half-lives cover an enormous range. Hydrogen-5 lasts about 8.6 × 10⁻²³ seconds, while tellurium-128 has a half-life longer than 2.25 × 10²⁴ years—a difference of nearly 54 orders of magnitude.
