Splet17. jan. 2024 · Short Half-lives = Non-existent Elements? With certain elements having very short half-lives, it’s fair to believe that certain elements’ atoms will experience radioactive decay at such a fast rate that they rapidly cease to exist. Splet18. sep. 2024 · In general there is an inverse relation between the half-life and the intensity of radioactivity of an isotope. Isotopes with a long half-life decay very slowly, and so produce fewer radioactive decays per second; their intensity is less. Istopes with shorter half-lives are more intense. drive to hard rock casino

SpletShorter half life means more decays/unit time for a given amount of sample. This means it will decay away sooner. Yes, that means for a given amount of time you will have more disintegrations in the shorter half-life sample. You could call this ‘more radioactive.’ This is only part of the equation though.
